Just an idea; like you said, titanium while relatively hard, it's not that hard compared to hardened steel, but what you could try to improve edge retention when slamming into stuff is carbidizing the edges of the blades. It's basically welding a thin layer of tungsten-carbide onto one side of the edge to give it a much harder surface. I know that some knifemakers do that when/if they make titanium blades.
@@alyero6341 Why? Titanium nitrade coating is way too thin to protect against impact damage; it's only to protect against wear of friction. Also, I don't think it would be anywhere near as easy to diy and if you are already at the point of "I want to pay a company to put protective coating on this", then DLC would be the better option anyways. But in this case you would want a layer that is hard to easily punch through other materials, while also having enough structural integrity to spread out the energy of impact to a wider area so the Titanium can then absorb it without deforming. It would be a thin layer, but not microscopic like a coating. At least that's the theory ;)
As an American beetleweight and antweight builder, the ultimate design that I have been working at is an overhead bar spinner that uses shuffle pods instead of wheels. This gives the bot a 25% weight bonus, allowing for a more powerful weapon motor and a heavier bar. Additionally, this would be made out of a central TPU chassis for maximum damage absorption with aluminum top and bottom armor for rigidity. Oh and by the way, that weapon blade being given away would come in quite handy for my first fairyweight build! 😉 Thanks for all the entertaining content and hard work!
I would build a hexagon shaped robot with 6 spinning blades on each corner, and make the wheels stick out on both ways so it can drive upside-down. Pretty redicoulos but i think its beautifull
As a high schooler I do vex robotics and the zip tie idea looks fantastic. Last year the competition used discs that had to be shot out so we use zip ties to prevent the discs from flipping backwards.
Im not sure how much torque you would need, but maybe twisting some string making an actuator could work with a small cellphone vibration motor. It should be substantially less weight and should be enough force to flip the bot
If I were to build a battle bot I would name it "Viceroy" due to it's dual mandible design intended to crush its opponents' frames. Think stag beetle mandible shape. Though maybe one mandible would be better because all the power goes to one arm instead of being split between two. In this case think hercules beetle mandible shape. The only real problem I can see is the holding/grappling rules restricting the crush timing to a minimum.
Hey Angus! I been a big fan of battlebots since first seeing the ABC reboot as a kid. I like to think it’s a big reason I developed enough of an interest in pursuing engineering as a career and I’m happy to say I’m now going into my sophomore year of college as a mechanical engineer. It’s been great seeing combat robotics evolve so much over the past years and seeing the success of robots such as Tantrum, Sawblaze, and Huge. I’d say if I were designing an all out dream robot it would be a cross between Tantrum and Whiplash. All of the control of a lifter, and the ability to set precise attacks. Throw in the drivetrain of Claw Viper and it would be an absolute powerhouse!
My plan is to make a little hub on wheels that could drive around, surrounded by a big horizontal belt drive. Just a big round spinning neoprene belt orbiting around a little drive robot. In my mind it would win by chucking the opposing robot at walls on contact. Admittedly, it's probably not a very consistent win condition, but at least it's dramatic. I've also long suspected that giving the hub robot enough traction to counter the force of the whirling belt would be a bit of a pain, though.
Hey Angus! It was great to see pancake live and looking forward to more exciting antweight stuff. After my bot got destroyed, i plan to redesign and build a new modular both that can swap to differemt weapon types making it able to compete in both non destructive and destructive categories next event!
I have been working on a 3lb robot that kinda looks like axe backwards. But I used a aluminum tube as the drum with a titanium bar on one side of it and all of the eltronics are inside the drum with the wheels on the outside. It works like a robot called noob tube but I put a rap around wedge that goes around one side so it can be somewhat defensive too. But this design is cool because around 3/4 of the weight is in the weapon.
I would probably just do Typhoon 2 with some kind of self-righting mechanism as my ultimate battle bot. The armor also being the weapon is a genius way to cut weight down to the point where they were able to power the thing with a small engine rather than the standard batteries, and the power that weapon had as a result is beyond terrifying. When your armor spins, every blow is glancing!
My dream combat robot, I'm actually in the process of designing. It is a double drum with both drums in the front. They would be supported in the middle with a pair of forks like Scorpios, but back to back as to push the opponent to the outside. The drums would be fully reversible, and the bot designed to drive up side down. This way, no self righting would be required. The drums would be independently controlled so the gyroscopic action can be negated or utilized for steering. This would probably end up a paper tank like minotaur.
Building a flipper that uses bent carbon fiber as a lightweight high strength spring would be cool, styled like some kind of jumping bug as it will probably go flying with how much energy carbon fiber can store.
@@BeefIngot replacing key parts on battlebots every battle is nothing unheard of apparently on some spinners blades rarely rast more than one or two battles armor plates have to freqnetly go thourgh major repairs and complete replacement
My wife wanted to make something like that only the flipper move in through both sides of the bots body. That way the robot itself could jump and flip over the robot. It would also get it one hell of a pushing force
All I know about carbon fiber that it's the worst material for springs. If you know of such applications I would be very curious to learn about a process to make it work. Kevlar would possibly be much better but It still will require some special binder as standart composites will be stiff as hell.
A flat robot using mechano wheels, with a different weapon on each side. For example, a ramp in one side, a vertical spinner on another, a spike hammer, and flipper arm on the two other sides. The mechano wheels would allow you to move in any direction so you can choose which weapon to attack with
That’s very cool that you were able to make a mini deathroll. I used to watch these competitions years ago and now that I started 3D printing, every time you do a video on them it makes me want to get into it more. The mini deathroll looks like it’ll be a menace.
The bully bot, I would make a robot that jumps and the glides/floats down ontop of the opposition and attacks them front the top, I'm thinking it jumps up a good 2-4.feet, expands wings to aim itself on top of the enemy and drops on it with a spiked feet, the top of it is hard and you can aim it sideways to jump into robots like a hammer. -praying to get the cool titanium thing 🤞🤣
The robot I always wanted was a specialized anti-horizontal spinner bot (I imagined this back when Tombstone was dominating everything): use squishy armor that would (hopefully) slow down and catch those crazy fast blades, but use their own force to ram a large spike on the side of my robot into the side of theirs. Possibly up the ante with a spring-powered punch system like they use on centerpunches. Since it uses the enemy's strength against it, I might call it Aikido. Wish I could be there across the bay at OpenSauce - tickets are all gone though. Good luck! I would love to see more robot combat content. I love battlebots but would like to see more between seasons.
As a big fan of the sport and a builder myself, I'ld like to see a ominous style omni directional undercutter (omnidirectional pancake?!), given that one of the main downsides of the omnidirectional wheels are the lack of pushing power that they have, and that is something that a horizontal don't need at all to be efective. Also the way that the wheel are positioned could give a fast rotation to the robot making it easy to attack the opponent's side. I don't know how well it would work but it seems to be something fun and chaotic to drive and watch.
Dream robot: Uhhh... Vacuum suction on the bottom, s.t.f. Inside of auxetic material, with auxetic material fused with polyacrylic acid and calcium acetate around it. With the vacuum and sponge like material going to be on it’s bottom to form legs, and pistons on the side with those deathroll saws on the sides(made of caulobacter cresentus glue dried up, and carbidizing the edges, and having a system to push it back up(piston) if it flips over.
I love the mini death roll. Always been a fan of battle bots. I've always found tombstone to be one of my favorites, but for a antweight I think your design is better for a hard hitter with less damage to the robot itself 😂
I don't want the weapon disc, but I'd like to say thanks for introducing me to combat robotics. It's one of my new favourite hobbies even if I suck. I recently upgraded my CR-10 so I could print nylon more easily for new chassis so my bots won't explode as much.
My dream battlebot resembles an upside-down traffic cone. It has a single track-ball wheel and uses gyrosensors and Segway-style control strategy to balance and move about on its one wheel. It can also telescope along its vertical axis, and expand quickly to hop. Its weapon is a downward-firing spike. It is a glorious combination of a OneWheel, pogo stick, and jackhammer. It is finicky, obscure, unique, and will deliver spectacular death-blows. You can include a righting mechanism if you're the sort of wimp who thinks high-performance aircraft should have ejection seats. An alternate version has wheels top and bottom and a hinge in the middle, allowing it to do flips and cartwheels.
Using the spining blade you made and using it vertically in the front (if the blade were balanced it could be used horizontally to counteract the gyro effect when turning and even use it as a self balancing feature making it harder to flip the bot as it would stay horizontal in the air). For locomotion just one power wheel in the back and a servo upfront that would touch the ground creating drag to steer the bot. With that much weight saving you could make a sturdy chassis to allow the bot to take a beating. Another option would be to have a massive capacitor and explode it when touching the other bot as a 1 shot weapon.
I love your combat robotics content! It makes me happy to see your stuff. I've been working on a US antweight hammer saw design for a while (yes before the BB finals lol), so far I've only run a wedge but I'm hoping to have the hammer saw design finished for the next local competition. Its gonna be tough to get into the right limit but I'm only 50-60g away so I think I can make it work.
I know triplecrown didn’t get too much battlebots screen time, but I really enjoyed seeing a swerve drive in a competition with usually pretty basic wheel layouts. So if I could design my dream robot, it would probably have a swerve drive (probably just two swerve pods instead of three) alongside a horizontal spinner on one side and a flipper on the other.
I would go for coaxial four wheel swerve (triple crown uses differential, and with that comes a very finicky drivetrain under high weight) with a vertical disk
As a fellow Aussie, I would love to make a battlebot called the Akubra, with a hat shaped top surrounded by weights on strings (like corks), that spins to act as the weapon. It will be self-righting because the bowl-shaped top and uneven weight distribution will put one side of the weapon in contact with the ground and the spinning will right it
A tip for heat inserted threads, I take the longest bolt available and thread it on the insert and heat it up, that way its easier to keep straight as it melts into place
Completely insane, this is the stuff that makes me exited for where this sport is going, as an upcoming builder myself, you're certainty an inspiration.
I want to make a heavy flywheel which drives a super grippy tyre on the top of a wedge bot through a special clutch. I had the realisation that the impact of a spinner with claws making contact breaks the attacker more often than the opponent. What breaks the opponent is throwing them really hard, and hard surfaces don't really hold onto the opponent very well. So the idea is getting under them so they're wedged up on top of a dragster tyre, then dumping the clutch to grip them like crazy and throw them as hard as any other spinner. Rather than a glancing blow, every time you can wait for the opponent to be fully resting on the tyre before throwing them. If you're upside down, you also get no resistance to spinning up the flywheel and the tyre can throw you hard enough to self-right.
Because for full-scales ones that extra few lbs won't make any difference. Machines are already 250 each, and many flippers are strong enough to lift a car.
My bot would be a ring spinner with wheels that pass through both sides. The ring would feature weapons on swingarms that use inertia to spread open and increase the reach while spinning. While at rest, an elastic band pulls the arms in. The ends of the arms feature a spike that will concentrate the forces into the opponent. I call this concept, Thornwhip
When I watched Battle Bots as a kid there was a bot called Hazard. It was just a trapezoid with flat walls, flat top / bottom, wheels and a flipper. Very simple and almost impossible to stop. I think I would want to try building it. Maybe I would add some triangular sloped armour on the sides for extra protection and to help prevent the off chance of landing on it's side.
Put traction grip pads under the front of the robot, so when the spinner engages the enemy and lifts the enemy, it pushes the front of your robot down and grips the floor. You need a little bit of spring at the front to hold the traction pad JUST above the floor and and a lot of traction pad area.
5:45 what a cool tool. I did my first insert the other day and wow was it horrible. I printed it with the recommended hole, but the insert ended up melting off center and leaving a big gap. Luckily it’s still strong enough, but next time maybe I’ll make a chamfer or something to guide it in place?
HI Maker's Muse do you have already videos talks about the Z-offset variations between filaments. I just find out, the Z-offset is very stable when I change filaments between ABS/PLA/PETG filaments for using 3.9mm as Z-offset, but as soon as I switched to use Wood filament (PLA based) I suddenly need to set it to 4.0mm to have good bed adherence. The same setting for other filaments will be too small and starts to observe elephant foots.
Seeing its my first time building one, i think i would start with a flat saw blade on a powerful motor and have some kind of special teeth bulit into it to destroy things with better. My first time again and its my first time to your channel. Love to win something but again i wish you luck in san fran. Best wishes all ahead full
So, one mechanical concept rules light weight battle bots. The ability to store up energy to unleash all at once, hitting far above the weight class would imply. This is why spinners are so common, because the ability to spin up the weapon to high RPM for a single blow allows even featherweights to hit like bullets. One idea I'd love to see is that idea taken to the extreme. A bot that uses elastic tension and a winch system to draw a metal spike back, then stab it into the enemy. like a crossbow that's made for melee. (No projectile, the bolt never actually leaves the weapon) I've seen this idea handled a different way in Robot Wars with Pain. That robot used a Co2 canister to fire a piston, but the weapon idea was the same. Stab the enemy at high speed.
Dream-bot concept: Swarm-bot - where the robot divides into multiple robots to attack as a pack. Most battlebot designs assume one opponent so will struggle against a swarm. E.g., 3 robots, the first, a vertical blade spinner, takes the attention of the opponent's weapon. Meanwhile the second, a lifter comes around the back to expose the drive wheels or some other vulnerability. The third, a pancake, sneaks under and destroys the drive wheels.
Deathroll with domed 360 degree bumpers to get under and flip your opponent then cut them to ribbons would be awesome! Bread is heavy. Could you use aluminum inserts with aluminum or titanium screws to save a bit more on weight and get in the bits you want? Or eliminate the inserts and go to self tapping screws?
I'd say micro toro or nightmare would be amazing. Toro with crazy powerful lifts! Nightmare with the huge wheel looking like a dinosaur would be too good!
@Maker's Muse, I thiunk I would make a Maximizer style bot that looks more like a scorpion with it's out-streched tail and the spining blade on the back. The front would be armored with the pincers made as large wedglets to get under half the opponent's body leading their side/wheels to the tail weapon.
I've always wanted to design a combat robot with an internal horizontal flywheel that is disconnected from the weapon by a clutch pack. This would allow the flywheel to build momentum even if pinned while hitting with power similar to a horizontal spinner. Rush the opponent, pin then or their weapon while internally spinning up my own, then delivery the death stroke. Good luck making that on an ant weight scale though!
I would do a stealth robot. Something that probally has never been done before. A robot with a good armor, but you cant see the weapon. It detects where your opponent is and then retracs a very sharp weapon using some very strong springs out of its body.
I am currently in the process of designing/building a robot that is a crusher (similar to Razer or Quantum), but the beak has a drill on it to deal more damage, and prevent the crushed robot from getting stuck to the beak. Thank you for all the videos and content! Your channel is awesome!
My ideal robot's main strategy would be to immobilize the competition. It would purposely have materials hanging off of it that would hopefully get tied up in the enemy robot. clog the wheels, the main weapon, and hopefully anything else that spins. Once its achieved this, it would have a pincher of some kind to squeeze the enemy, in hopes to pierce armor and delete electronics
Me personally, I would make a battlebot with a claw mechanism that SHOCKS other battlebots frying their components, and making them immobile! I think this a great idea and would be an outstanding competitor.
My ultimate design for a combat robot would be some sort of full body spinner with a full articulating walking system. I love the robot by the way, definitely one of the coolest at that weight class.
Hey Angus, just a quick question, do you still use G10 on you printers? i recently came across your vid about them again and was wondering how they are a year later.
I'd build a 4 way low profile wedge that high centers the other bot and jaws of life style cuts it in half via proximity sensor if auto control is allowed. I would cam the jaws for fast actuation transitioning to extreme torque. Alternatively, two low exposure, top, fixed blades coupled with a projecting saw that runs within a pair of barbed harpoons might look pretty impressive. Perhaps timed blades in an x-pattern, with a profile similar to your deathroll, which rotate away from your bot in a counter clockwise fashion would throw some serious force at the walls of the arena.
Some neat notes on Ti anodizing. There are constraints on what colors can be had. If you've seen motor oil on a puddle... Its those colors, because it's the same effect. White like comes in all sorts of wavelengths. Some of it reflects of the surface of the oil. Some goes thru the oil film, reflects off the water, and comes back. Now the tricky bit. Any given wavelength is now out of phase with it's twin because the light that went thru the oil twice traveled further (and slower) to make that trip. Wavelengths of some length will amplify their twins wave and other wavelengths will cancel. Which wavelengths receive which can be changed by varying the oil film thickness. The thickness of oil varies "in the wild" so you get that rainbow effect. The reason the available color set is somewhat limited is because it's white light that has had one color cancelled out of it. Or instead of oil, the Ti oxide plating layer thickness. The reason it's effected by voltage is the oxide layer itself higher resistance so at low voltage you plate on a thin layer and it self regulates to pretty much stopping the plating. You need higher current to plate more. You get higher current by upping the voltage. It is actually possible to get thicker plating layers at lower voltage. It just requires accepting that the time soars thru the roof.
That's wild! Thanks for the detailed explanation. If you go beyond a certain voltage and oxide thickness, do the colours cycle again? Or do they get duller?
@@MakersMuse They kinda cycle as thickness increases but it gets really messy in certain spots. For instance the "first" green is usually pretty ugly and it's easy to fall into the yellow right next to it. The "2nd" green up around 115v tends to be prettier. If you look at a color chart you can see why folks with an affordable benchtop power supply don't have a good answer to your question beyond that 😂
My idea for an ant weight b-bot: it would be called "the hider", the hider would be basically a box made of polycarbonate with vertical titanium sheets (up to a 0.7 cm long) connected on the top to nicely slide onto the engraved plastic for protection against horizontal spinning weapons (best in ant weight) and for easy repair. It would also have silicon rubber on the bottom edges. Why? Because it could ''hide'' by moving it's two wheels up so the robot would stand still. The hider would do that really quickly so it would have a better chance of not falling into the pit and getting itself more time to push the other opponent. The hider also wouldn't have a roof so a double-sided moving mechanism would work even if the robot is flipped. I hope to get this piece as I'm not able to make one myself but I also wish everyone else good luck.
I've been wanting to build a robot that has a welder built in, and just welds the other bot to itself, or to the ground. Imagine if you show up with a big tack welding hug, and the other robot just fuses to itself. No idea how to fit that in any weight class, but I think it would be hilarious.
Ultimate robot build would likely be an internally reinforced carbon fiber pyramid, with a high rpm titanium disc/blade protruding out of one face. If I had to name it I would call it Terror-hedron!
when was in highschool / middle school (im 35 now) i had so many bot designs and i could just go on for hours but with how the tech has evolved so much i doubt any of my ideas could even work today. i always loved full body spinners but a design i saw some one else do was a design i had as a kid that is completely useless again metal armor or full scale bot, but in smaller classes where plastic is mostly used it works better than it should. the design im talking about is an over head saw design that cuts from above and would slice right through most plastic, but its been done and its devastating
a tiny little butane torch and 3 little spinners going in alternating directions and thin titanium plates for protection. It would be pretty hard to pull off the torch, but I feel like it could work.
OMG, the sound of that spinning up is crazy. however, that gave me an idea of making a defense first bot that has essentially a arm clamp that has brillo pad curtains on the end of it to essentially clog up the opponents motorized device.
I've had a really cool idea for a battlebot for a while now. I call it Moray. It's essentially one of the kinds that uses a hydraulic press with a sharp point to puncture through the shell of a bot. The unique thing about my design though is that it has a secondary motorized jaw so that it can grab the opponent really quickly. I think it's a cool idea since puncture weapons are really effective if they can get a grip but they are limited by the speed of the jaw, that's what the secondary jaw is meant to help with. The general strategy would be to lock on with the fast motorized jaw and then cause damage with the hydraulic jaw. The name is a refference to eels which have a second jaw that bites it's prey when the outer jaw is holding on. Obviously this design would be intended for the huge bots seen on Battlebots.
I always wanted to build a robot like Minion, with a basic wedge design, a vertical dorsally mounted circular saw, a smaller trio of vertical circular saws on the back, and a self-righting arm that folded flush to the body. Basically, imagine the Aurora [possibly fictional] spy plane, and make it into a wedge and vertical circular saw type fighting robot.
I don't know how effective it would be, but I'm envisioning a self-righting chassis shape like a gömböc. Or a pill. A cylindrical spinning drum with the drive inside it would act as armor as well as weapon. Keep the center of mass low so it can drive with a wheel on either side of the drum that's wider than the drum, and cap it off with rounded shields. There would be no need for self-righting mechanisms as it would always land on its wheels ready to go
My 2 favourite bots have always been hypno disc and razer. The pure destruction of hypno disc led to some incredible moments and watching razer just bite down on anything it could grab and just bite right through it. Not sure how transmittable razer is, can't imagine any system even relatively close could be light. But hypno is just a horizontal flywheel with some special teeth. Been considering getting into combat bots but I'm already time starved as is, reckon it'll be a side project eventually though
A grabber that can gum up opponents spinning weapons, with a pile bunker drill that it can use to once the opponent has been grabbed would be my design.
My idea for a battle bot is a vertically split sphere with a central band that has a tail off of it with a spiked or mace like end. The two halves of the sphere are the wheels with separate motors in each. They can counter rotate creating a spinning happier throw type movement for the tail. The weighted central tray with battery and electronics could have a motor to engage gear teeth on the inside of the central ring allowing possibly over hand hammering. With the main body being a sphere and the internal main chassis being off set down from center it would inherently be automatically self righting. A little tread texture or knurling around the edge of the half spherical wheel/body forms your tires. That was just my idea of a phantasm sphere ankylosaur bot.
That lil thing is sick! If I were to make one.... A spinning top. Like a beyblade. If the opponent wants aggression points, they'll have to charge a solo spinning blade.
I was wondering if you would like to upload or link the files somewhere , as it seems really interesting and i would like to try and build an arm to flip it.
I look forward to seeing it at Open Sauce. The epoxying of the disc on to the motor shaft worries me. Have you tested it enough to make sure it doesn’t fail when the titanium disc hits when at full speed?
My ultimate battle bot design would be a bot with 2 blades in the front (one on top of each other) but spinning opposite directions. Then have the blades designed in a way so when they're spinning they make a screeching sound.

Just an idea; like you said, titanium while relatively hard, it's not that hard compared to hardened steel, but what you could try to improve edge retention when slamming into stuff is carbidizing the edges of the blades. It's basically welding a thin layer of tungsten-carbide onto one side of the edge to give it a much harder surface. I know that some knifemakers do that when/if they make titanium blades.
Never heard of this before, sounds like a great idea though.
Look closer at any tungsten carbide tipped drill bit and you'll see exactly this
This tbh
maybe titanium nitrade (golden coating on drill bits - super hard) could be an option?
@@alyero6341 Why? Titanium nitrade coating is way too thin to protect against impact damage; it's only to protect against wear of friction. Also, I don't think it would be anywhere near as easy to diy and if you are already at the point of "I want to pay a company to put protective coating on this", then DLC would be the better option anyways. But in this case you would want a layer that is hard to easily punch through other materials, while also having enough structural integrity to spread out the energy of impact to a wider area so the Titanium can then absorb it without deforming. It would be a thin layer, but not microscopic like a coating. At least that's the theory ;)

As an American beetleweight and antweight builder, the ultimate design that I have been working at is an overhead bar spinner that uses shuffle pods instead of wheels. This gives the bot a 25% weight bonus, allowing for a more powerful weapon motor and a heavier bar. Additionally, this would be made out of a central TPU chassis for maximum damage absorption with aluminum top and bottom armor for rigidity. Oh and by the way, that weapon blade being given away would come in quite handy for my first fairyweight build! 😉

If I were to build a battle bot I would name it "Viceroy" due to it's dual mandible design intended to crush its opponents' frames. Think stag beetle mandible shape.
Though maybe one mandible would be better because all the power goes to one arm instead of being split between two. In this case think hercules beetle mandible shape.
The only real problem I can see is the holding/grappling rules restricting the crush timing to a minimum.

I have been working on a 3lb robot that kinda looks like axe backwards. But I used a aluminum tube as the drum with a titanium bar on one side of it and all of the eltronics are inside the drum with the wheels on the outside. It works like a robot called noob tube but I put a rap around wedge that goes around one side so it can be somewhat defensive too. But this design is cool because around 3/4 of the weight is in the weapon.
2:55 Odd question, but where did you find the full production-CAD of Deathroll??
I would probably just do Typhoon 2 with some kind of self-righting mechanism as my ultimate battle bot. The armor also being the weapon is a genius way to cut weight down to the point where they were able to power the thing with a small engine rather than the standard batteries, and the power that weapon had as a result is beyond terrifying. When your armor spins, every blow is glancing!
My dream combat robot, I'm actually in the process of designing. It is a double drum with both drums in the front. They would be supported in the middle with a pair of forks like Scorpios, but back to back as to push the opponent to the outside. The drums would be fully reversible, and the bot designed to drive up side down. This way, no self righting would be required. The drums would be independently controlled so the gyroscopic action can be negated or utilized for steering. This would probably end up a paper tank like minotaur.
Building a flipper that uses bent carbon fiber as a lightweight high strength spring would be cool, styled like some kind of jumping bug as it will probably go flying with how much energy carbon fiber can store.
I feel like that carbon fiber would deteriorate within a match or 2 with the repeated stresses
@@BeefIngot Replace after every match, to get the most out of high performance material
@@BeefIngot replacing key parts on battlebots every battle is nothing unheard of
apparently on some spinners blades rarely rast more than one or two battles
armor plates have to freqnetly go thourgh major repairs and complete replacement
My wife wanted to make something like that only the flipper move in through both sides of the bots body. That way the robot itself could jump and flip over the robot. It would also get it one hell of a pushing force
All I know about carbon fiber that it's the worst material for springs. If you know of such applications I would be very curious to learn about a process to make it work. Kevlar would possibly be much better but It still will require some special binder as standart composites will be stiff as hell.
flamethrower that heats a chainsaw that turns very fast and the bod has a dragon theme and to reverse it has a rotating blade as a tail🐲🔥

A flat robot using mechano wheels, with a different weapon on each side. For example, a ramp in one side, a vertical spinner on another, a spike hammer, and flipper arm on the two other sides. The mechano wheels would allow you to move in any direction so you can choose which weapon to attack with
That’s very cool that you were able to make a mini deathroll. I used to watch these competitions years ago and now that I started 3D printing, every time you do a video on them it makes me want to get into it more. The mini deathroll looks like it’ll be a menace.
Do it brah
The bully bot, I would make a robot that jumps and the glides/floats down ontop of the opposition and attacks them front the top, I'm thinking it jumps up a good 2-4.feet, expands wings to aim itself on top of the enemy and drops on it with a spiked feet, the top of it is hard and you can aim it sideways to jump into robots like a hammer.
-praying to get the cool titanium thing 🤞🤣
The robot I always wanted was a specialized anti-horizontal spinner bot (I imagined this back when Tombstone was dominating everything): use squishy armor that would (hopefully) slow down and catch those crazy fast blades, but use their own force to ram a large spike on the side of my robot into the side of theirs. Possibly up the ante with a spring-powered punch system like they use on centerpunches. Since it uses the enemy's strength against it, I might call it Aikido. Wish I could be there across the bay at OpenSauce - tickets are all gone though. Good luck! I would love to see more robot combat content. I love battlebots but would like to see more between seasons.
In UK robot wars there was an anti horizontal spinner robot called gabriel that was just meant to not die (to try and counter carbide)
or you could just have a wedge
Has anyone else got a scam for telegram me saying that you won?
As a big fan of the sport and a builder myself, I'ld like to see a ominous style omni directional undercutter (omnidirectional pancake?!), given that one of the main downsides of the omnidirectional wheels are the lack of pushing power that they have, and that is something that a horizontal don't need at all to be efective. Also the way that the wheel are positioned could give a fast rotation to the robot making it easy to attack the opponent's side. I don't know how well it would work but it seems to be something fun and chaotic to drive and watch.
Could one manage a tactical nuke bot in less than 150 grams?
Dream robot:
Uhhh...
Vacuum suction on the bottom, s.t.f. Inside of auxetic material, with auxetic material fused with polyacrylic acid and calcium acetate around it. With the vacuum and sponge like material going to be on it’s bottom to form legs, and pistons on the side with those deathroll saws on the sides(made of caulobacter cresentus glue dried up, and carbidizing the edges, and having a system to push it back up(piston) if it flips over.
I love the mini death roll. Always been a fan of battle bots. I've always found tombstone to be one of my favorites, but for a antweight I think your design is better for a hard hitter with less damage to the robot itself 😂
A robot that could jump over opponents would be really cool tho I'm not to sure how well it would work in a actual fight
Great project! Mini Deathroll looks clean!
Fully agreed & glad to meet you here ☺
I really like Hazard, but it’s the spinning blades and winnings.
I don't want the weapon disc, but I'd like to say thanks for introducing me to combat robotics. It's one of my new favourite hobbies even if I suck. I recently upgraded my CR-10 so I could print nylon more easily for new chassis so my bots won't explode as much.
That's so cool! Doesn't matter how good your bot is as long as you're having fun building and competing.
@@MakersMuse it is a lot of fun. Currently designing my first beetleweight!
@@jb-br8bfyou need to make TH-cam videos about your bots. I also want to learn to make these bots at home but I'm completely rookie to electronics.
My dream battlebot resembles an upside-down traffic cone. It has a single track-ball wheel and uses gyrosensors and Segway-style control strategy to balance and move about on its one wheel. It can also telescope along its vertical axis, and expand quickly to hop. Its weapon is a downward-firing spike. It is a glorious combination of a OneWheel, pogo stick, and jackhammer. It is finicky, obscure, unique, and will deliver spectacular death-blows. You can include a righting mechanism if you're the sort of wimp who thinks high-performance aircraft should have ejection seats. An alternate version has wheels top and bottom and a hinge in the middle, allowing it to do flips and cartwheels.
Would love to do a super-capacitor bot that just blows the other bots up with a light touch 😂
😂 good luck sneaking that in!
Using the spining blade you made and using it vertically in the front (if the blade were balanced it could be used horizontally to counteract the gyro effect when turning and even use it as a self balancing feature making it harder to flip the bot as it would stay horizontal in the air).
For locomotion just one power wheel in the back and a servo upfront that would touch the ground creating drag to steer the bot.
With that much weight saving you could make a sturdy chassis to allow the bot to take a beating.
Another option would be to have a massive capacitor and explode it when touching the other bot as a 1 shot weapon.
I love your combat robotics content! It makes me happy to see your stuff. I've been working on a US antweight hammer saw design for a while (yes before the BB finals lol), so far I've only run a wedge but I'm hoping to have the hammer saw design finished for the next local competition. Its gonna be tough to get into the right limit but I'm only 50-60g away so I think I can make it work.
@makersmuse it looks like you have a phisher in the comments
@@lizrrdbreathI got similar message, definitely a scam
You blow my mind...........I love watching these competitions, and you do this in a smaller way. How fun......I mean seriously......wow!!!
I know triplecrown didn’t get too much battlebots screen time, but I really enjoyed seeing a swerve drive in a competition with usually pretty basic wheel layouts. So if I could design my dream robot, it would probably have a swerve drive (probably just two swerve pods instead of three) alongside a horizontal spinner on one side and a flipper on the other.
I would go for coaxial four wheel swerve (triple crown uses differential, and with that comes a very finicky drivetrain under high weight) with a vertical disk
Triple Crown wasn't completed by the time it "fought". I think the only thing working was its drive.
As a fellow Aussie, I would love to make a battlebot called the Akubra, with a hat shaped top surrounded by weights on strings (like corks), that spins to act as the weapon. It will be self-righting because the bowl-shaped top and uneven weight distribution will put one side of the weapon in contact with the ground and the spinning will right it
Please more 3d printing with combat robots 🔥❤
on the main channel!)
A tip for heat inserted threads, I take the longest bolt available and thread it on the insert and heat it up, that way its easier to keep straight as it melts into place
Completely insane, this is the stuff that makes me exited for where this sport is going, as an upcoming builder myself, you're certainty an inspiration.
If I were building something for ant weight I'd have to go with a horizontal spinner & make an homage to the original bully of Battle Bots, Tombstone.
Will you be at the FANTS antweight event in Brisbane next weekend? (15 July)
I want to make a heavy flywheel which drives a super grippy tyre on the top of a wedge bot through a special clutch. I had the realisation that the impact of a spinner with claws making contact breaks the attacker more often than the opponent. What breaks the opponent is throwing them really hard, and hard surfaces don't really hold onto the opponent very well. So the idea is getting under them so they're wedged up on top of a dragster tyre, then dumping the clutch to grip them like crazy and throw them as hard as any other spinner. Rather than a glancing blow, every time you can wait for the opponent to be fully resting on the tyre before throwing them. If you're upside down, you also get no resistance to spinning up the flywheel and the tyre can throw you hard enough to self-right.
what are the electronics for this?
Instead of self righting, why not add a suction fan to the bottom? you could easily have 10+ pounds of downward force and make it unflipable
Because for full-scales ones that extra few lbs won't make any difference. Machines are already 250 each, and many flippers are strong enough to lift a car.
My bot would be a ring spinner with wheels that pass through both sides. The ring would feature weapons on swingarms that use inertia to spread open and increase the reach while spinning. While at rest, an elastic band pulls the arms in. The ends of the arms feature a spike that will concentrate the forces into the opponent. I call this concept, Thornwhip
When I watched Battle Bots as a kid there was a bot called Hazard. It was just a trapezoid with flat walls, flat top / bottom, wheels and a flipper. Very simple and almost impossible to stop. I think I would want to try building it. Maybe I would add some triangular sloped armour on the sides for extra protection and to help prevent the off chance of landing on it's side.
Put traction grip pads under the front of the robot, so when the spinner engages the enemy and lifts the enemy, it pushes the front of your robot down and grips the floor. You need a little bit of spring at the front to hold the traction pad JUST above the floor and and a lot of traction pad area.
5:45 what a cool tool. I did my first insert the other day and wow was it horrible. I printed it with the recommended hole, but the insert ended up melting off center and leaving a big gap.
Luckily it’s still strong enough, but next time maybe I’ll make a chamfer or something to guide it in place?
HI Maker's Muse do you have already videos talks about the Z-offset variations between filaments. I just find out, the Z-offset is very stable when I change filaments between ABS/PLA/PETG filaments for using 3.9mm as Z-offset, but as soon as I switched to use Wood filament (PLA based) I suddenly need to set it to 4.0mm to have good bed adherence. The same setting for other filaments will be too small and starts to observe elephant foots.
Seeing its my first time building one, i think i would start with a flat saw blade on a powerful motor and have some kind of special teeth bulit into it to destroy things with better. My first time again and its my first time to your channel. Love to win something but again i wish you luck in san fran. Best wishes all ahead full
So, one mechanical concept rules light weight battle bots. The ability to store up energy to unleash all at once, hitting far above the weight class would imply.
This is why spinners are so common, because the ability to spin up the weapon to high RPM for a single blow allows even featherweights to hit like bullets.
One idea I'd love to see is that idea taken to the extreme. A bot that uses elastic tension and a winch system to draw a metal spike back, then stab it into the enemy. like a crossbow that's made for melee. (No projectile, the bolt never actually leaves the weapon)
I've seen this idea handled a different way in Robot Wars with Pain. That robot used a Co2 canister to fire a piston, but the weapon idea was the same. Stab the enemy at high speed.
Dream-bot concept: Swarm-bot - where the robot divides into multiple robots to attack as a pack. Most battlebot designs assume one opponent so will struggle against a swarm. E.g., 3 robots, the first, a vertical blade spinner, takes the attention of the opponent's weapon. Meanwhile the second, a lifter comes around the back to expose the drive wheels or some other vulnerability. The third, a pancake, sneaks under and destroys the drive wheels.
Deathroll with domed 360 degree bumpers to get under and flip your opponent then cut them to ribbons would be awesome!
Bread is heavy. Could you use aluminum inserts with aluminum or titanium screws to save a bit more on weight and get in the bits you want? Or eliminate the inserts and go to self tapping screws?
building deadly robota and wearing a daleks shirt LoL .. I like
This little bot is AMAZING!
you should make more and sell them, I would buy one
I'd say micro toro or nightmare would be amazing. Toro with crazy powerful lifts! Nightmare with the huge wheel looking like a dinosaur would be too good!
My dream battle robot combines sleek, humanoid aesthetics with advanced functionality, featuring a durable, agile frame, integrated weapons systems, versatile sensors, and seamless team coordination capabilities.
@Maker's Muse, I thiunk I would make a Maximizer style bot that looks more like a scorpion with it's out-streched tail and the spining blade on the back. The front would be armored with the pincers made as large wedglets to get under half the opponent's body leading their side/wheels to the tail weapon.
What motor did you use for this bot? I'm looking for a high torque motor for an ant weight bot
I've always wanted to design a combat robot with an internal horizontal flywheel that is disconnected from the weapon by a clutch pack. This would allow the flywheel to build momentum even if pinned while hitting with power similar to a horizontal spinner. Rush the opponent, pin then or their weapon while internally spinning up my own, then delivery the death stroke. Good luck making that on an ant weight scale though!
I would do a stealth robot. Something that probally has never been done before. A robot with a good armor, but you cant see the weapon. It detects where your opponent is and then retracs a very sharp weapon using some very strong springs out of its body.
I am currently in the process of designing/building a robot that is a crusher (similar to Razer or Quantum), but the beak has a drill on it to deal more damage, and prevent the crushed robot from getting stuck to the beak.
Thank you for all the videos and content! Your channel is awesome!
This is what I love about 3d printing. it gives anyone the ability to create their wildest dreams.
My ideal robot's main strategy would be to immobilize the competition. It would purposely have materials hanging off of it that would hopefully get tied up in the enemy robot. clog the wheels, the main weapon, and hopefully anything else that spins. Once its achieved this, it would have a pincher of some kind to squeeze the enemy, in hopes to pierce armor and delete electronics
Me personally, I would make a battlebot with a claw mechanism that SHOCKS other battlebots frying their components, and making them immobile! I think this a great idea and would be an outstanding competitor.
My ultimate design for a combat robot would be some sort of full body spinner with a full articulating walking system. I love the robot by the way, definitely one of the coolest at that weight class.
Hey Angus, just a quick question, do you still use G10 on you printers? i recently came across your vid about them again and was wondering how they are a year later.
I'd build a 4 way low profile wedge that high centers the other bot and jaws of life style cuts it in half via proximity sensor if auto control is allowed. I would cam the jaws for fast actuation transitioning to extreme torque. Alternatively, two low exposure, top, fixed blades coupled with a projecting saw that runs within a pair of barbed harpoons might look pretty impressive. Perhaps timed blades in an x-pattern, with a profile similar to your deathroll, which rotate away from your bot in a counter clockwise fashion would throw some serious force at the walls of the arena.
Probably the most polished Antweight/Fairy I have ever seen; Looking great!
Some neat notes on Ti anodizing.
There are constraints on what colors can be had. If you've seen motor oil on a puddle... Its those colors, because it's the same effect.
White like comes in all sorts of wavelengths. Some of it reflects of the surface of the oil. Some goes thru the oil film, reflects off the water, and comes back.
Now the tricky bit. Any given wavelength is now out of phase with it's twin because the light that went thru the oil twice traveled further (and slower) to make that trip. Wavelengths of some length will amplify their twins wave and other wavelengths will cancel. Which wavelengths receive which can be changed by varying the oil film thickness. The thickness of oil varies "in the wild" so you get that rainbow effect. The reason the available color set is somewhat limited is because it's white light that has had one color cancelled out of it.
Or instead of oil, the Ti oxide plating layer thickness.
The reason it's effected by voltage is the oxide layer itself higher resistance so at low voltage you plate on a thin layer and it self regulates to pretty much stopping the plating. You need higher current to plate more. You get higher current by upping the voltage.
It is actually possible to get thicker plating layers at lower voltage. It just requires accepting that the time soars thru the roof.
That's wild! Thanks for the detailed explanation. If you go beyond a certain voltage and oxide thickness, do the colours cycle again? Or do they get duller?
@@MakersMuse
They kinda cycle as thickness increases but it gets really messy in certain spots. For instance the "first" green is usually pretty ugly and it's easy to fall into the yellow right next to it. The "2nd" green up around 115v tends to be prettier.
If you look at a color chart you can see why folks with an affordable benchtop power supply don't have a good answer to your question beyond that 😂
Really interesting, cheers!
My Favorit robot Design would use heater elements to burn holes in the opponents robot.
The very second you said "Battlebots", an incomprehensible wave of nostalgia was sent through my entire body, and I felt it all.
My idea for an ant weight b-bot:
it would be called "the hider",
the hider would be basically a box made of polycarbonate with vertical titanium sheets (up to a 0.7 cm long) connected on the top to nicely slide onto the engraved plastic for protection against horizontal spinning weapons (best in ant weight) and for easy repair.
It would also have silicon rubber on the bottom edges.
Why? Because it could ''hide'' by moving it's two wheels up so the robot would stand still. The hider would do that really quickly so it would have a better chance of not falling into the pit and getting itself more time to push the other opponent. The hider also wouldn't have a roof so a double-sided moving mechanism would work even if the robot is flipped.
I hope to get this piece as I'm not able to make one myself but I also wish everyone else good luck.
The weapon is clearly overpowred, shave weight here, use smaller motor and more skeletonised blade especially towards the inside.
I've been wanting to build a robot that has a welder built in, and just welds the other bot to itself, or to the ground. Imagine if you show up with a big tack welding hug, and the other robot just fuses to itself. No idea how to fit that in any weight class, but I think it would be hilarious.
how much the avrage robot cost?
Ultimate robot build would likely be an internally reinforced carbon fiber pyramid, with a high rpm titanium disc/blade protruding out of one face. If I had to name it I would call it Terror-hedron!
when was in highschool / middle school (im 35 now) i had so many bot designs and i could just go on for hours but with how the tech has evolved so much i doubt any of my ideas could even work today. i always loved full body spinners but a design i saw some one else do was a design i had as a kid that is completely useless again metal armor or full scale bot, but in smaller classes where plastic is mostly used it works better than it should. the design im talking about is an over head saw design that cuts from above and would slice right through most plastic, but its been done and its devastating
a tiny little butane torch and 3 little spinners going in alternating directions and thin titanium plates for protection. It would be pretty hard to pull off the torch, but I feel like it could work.
OMG, the sound of that spinning up is crazy. however, that gave me an idea of making a defense first bot that has essentially a arm clamp that has brillo pad curtains on the end of it to essentially clog up the opponents motorized device.
I've had a really cool idea for a battlebot for a while now. I call it Moray. It's essentially one of the kinds that uses a hydraulic press with a sharp point to puncture through the shell of a bot. The unique thing about my design though is that it has a secondary motorized jaw so that it can grab the opponent really quickly. I think it's a cool idea since puncture weapons are really effective if they can get a grip but they are limited by the speed of the jaw, that's what the secondary jaw is meant to help with. The general strategy would be to lock on with the fast motorized jaw and then cause damage with the hydraulic jaw. The name is a refference to eels which have a second jaw that bites it's prey when the outer jaw is holding on. Obviously this design would be intended for the huge bots seen on Battlebots.
The Kraken of Seventh Robot Wars had a similar mechanism. Not much distance on the hydraulic though.
I always wanted to build a robot like Minion, with a basic wedge design, a vertical dorsally mounted circular saw, a smaller trio of vertical circular saws on the back, and a self-righting arm that folded flush to the body. Basically, imagine the Aurora [possibly fictional] spy plane, and make it into a wedge and vertical circular saw type fighting robot.
I don't know how effective it would be, but I'm envisioning a self-righting chassis shape like a gömböc. Or a pill. A cylindrical spinning drum with the drive inside it would act as armor as well as weapon. Keep the center of mass low so it can drive with a wheel on either side of the drum that's wider than the drum, and cap it off with rounded shields. There would be no need for self-righting mechanisms as it would always land on its wheels ready to go
i find the tiny battlebots so funny. all of them are so light that the smallest hit sends both opponents to the other side of the arena.
My 2 favourite bots have always been hypno disc and razer. The pure destruction of hypno disc led to some incredible moments and watching razer just bite down on anything it could grab and just bite right through it. Not sure how transmittable razer is, can't imagine any system even relatively close could be light. But hypno is just a horizontal flywheel with some special teeth. Been considering getting into combat bots but I'm already time starved as is, reckon it'll be a side project eventually though
A grabber that can gum up opponents spinning weapons, with a pile bunker drill that it can use to once the opponent has been grabbed would be my design.
My idea for a battle bot is a vertically split sphere with a central band that has a tail off of it with a spiked or mace like end. The two halves of the sphere are the wheels with separate motors in each. They can counter rotate creating a spinning happier throw type movement for the tail. The weighted central tray with battery and electronics could have a motor to engage gear teeth on the inside of the central ring allowing possibly over hand hammering. With the main body being a sphere and the internal main chassis being off set down from center it would inherently be automatically self righting. A little tread texture or knurling around the edge of the half spherical wheel/body forms your tires. That was just my idea of a phantasm sphere ankylosaur bot.
Hey Angus. Just a huge flywheel like your Deathroll. The motos, everything inside the hub. You can't get near it without being trashed.
That lil thing is sick!
If I were to make one.... A spinning top. Like a beyblade. If the opponent wants aggression points, they'll have to charge a solo spinning blade.
I was wondering if you would like to upload or link the files somewhere , as it seems really interesting and i would like to try and build an arm to flip it.
I look forward to seeing it at Open Sauce. The epoxying of the disc on to the motor shaft worries me. Have you tested it enough to make sure it doesn’t fail when the titanium disc hits when at full speed?
My ultimate battle bot design would be a bot with 2 blades in the front (one on top of each other) but spinning opposite directions. Then have the blades designed in a way so when they're spinning they make a screeching sound.
If your other bot was called pancake, you should call this one swiss roll! Both a homage to death roll, and also a running theme with baked goods!
