That spline shaft looked like certified hard work. Props.
jerry rigged. That's my favorite way of doing things
@@MushookieMan I call it farmer engineering. Doing what ya need to do, with what ya have on hand. Sometimes that involves making your own tool because it's a heck of a lot cheaper than going and buying some Custom Tool that you're going to use once.
@@keithyinger3326 I call it 'doing it wrong the first time'.
it probably beter quality than what i do at work on a real cnc
@@MushookieMan If it works correctly, its not been done wrong. Maybe its been done *inefficiently,* not wrong.
Oh man I felt bad for the spider, but seems like he was going for a win in building rather than fighting. Great fun, congrats Angus 👍
Redback is definitely a work of art! I didn't want to destroy it.
KISS is probably the best philosophy to use when it comes to a remote controlled "battle-robot".
Ya, I don't think he had any intention to win, as he doesn't even seem to have any WAY to win a fight, if the enemy doesn't break itself.
@@Nevir202 It has that saw blade right on the front, but it wont do much.
some people do build combat bots with fun being more on the menu than being competitive, and the "want to make something cool" crowd are more attracted to the Sportsman comps for obvious reasons.
Finally, I have missed your combat robotics videos so much. Glad to see them again. Would love to see you go to something like Norwalk Havoc!
Would be cool to make some international events!
@MORE Maker's Muse, the US would love to have you!
Awesome bot Angus - it's just a pity we didn't fight (except in the rumble)! Even seeing it in person I didn't appreciate how you did the lifting mechanism - that's a nifty design, and a great video as always
I can barely remember the rumble but looks like we had a few good engagements! Great to catch up and I definitely need to try those brushless drill conversions some time, I have so many old gearmotors...
@@MakersMuse I have a question. I'm trying to build my own robot and I have fairly powerful 12V 0.5A motors. I'm trying to find corresponding esc to remote control it, but I can't find any that fit the 12V 0.5A parameters? Do you have a god website to recommend for ESCs?

THE HASH RINGING

@@unicycleboi5874 THE RASH RINGING RASHER 😱 🤨 📸☠️
Custom made to settle your hash!
"keeping you in place while i lower a saw into you" is such a classic Robot Wars design, glad to see stuff like that's still being built.
Can't believe you ground that spline shaft by hand & it not only worked, it held up the whole way through too! Really impressive! Excellent work & congrats on 3rd place!
I'm very impressed by the lifting mechanism, when i saw it working in the arena I thought you had a separate servo for the lifter
3rd place is nothing to sneeze at. Building robots to fight each other is a whole new level of engineering difficulty and you tackled that challenge wonderfully! Also mad props for HAND grinding those splines!
17:55 seeing Glen suplex your bot into the pit was such unnecessary flare on his end and I absolutely love it
Seeing amazing walkers and very complex commercial grade robots get obliterated by small DIY machines at these events always seems like a waste but at the same time is super satisfying.
I guess everyone knows what they're getting into, but imagine putting weeks or months into a build and then it's destroyed in a way that can't be repaired in the first fight
As much robot combat content as you want to make, I'll always watch it!
ditto!
Looks like lots of fun. Thanks for sharing your adventure with us.
It was fun to see the Band Saw too, that is the same one we have in our High School Robotics Lab.
One recommendation concerning the bent arm and bolt holes. Fusion 360 has an amazing stress analysis tool. I had to design a robotic gripper at work and weight was a major concern and using a the tool, I could determine exactly where I needed material and where I didn't.
Love seeing videos on this topic!!!!! Please continue to create and share them! After so much time and hinting of your enthusiasm for robot combat, we finally got to see a propper video on it, hope to see more, and any details you improve or move in a new direction with.
Enjoy the Sin City Slug Fest, its been great so far! always hoped to get involved in robot combat, its great to see a grassroots bots and see how they were conceived and implemented as the problems are ironed out.
Big up yourself for that spline shaft. I wish you went more into how it's wired and controlled
This was *such* a fun video to watch! I loved hearing about all the details of your build and the competition. PCBWAY has so many things to offer to help makers these days. Just a fantastic video to watch. I can’t wait for the next installment!
I like the lifter Saw Combo, pretty unique take on the saw bot concept.
Fun idea (though probably not as practical as the spike), what if added a spatula as the lifter to further add to the Hash Slinging Slasher theme
This was really cool! Had no idea that Sportsman category exists, that's really cool. The KE weapon meta was getting pretty sweaty, so seeing some alternatives opening up is great to see.
It's why we started it here, the barrier to entry for the unrestricted class was becoming way too high sadly. You either made a boring brick / wedge or invested thousands into a robot that would be potentially obliterated in its first fight. Sportsman fights last longer and still have plenty of entertainment value!
@@moremakersmuse as an australian i'm seriously interested in joining something like this, but i cant seem to find any info online about battle bots here. do you know where i can find more info?
@@the_donz You can try joining the RobowarsAustralia facebook group !
@@the_donz What state are you in? SA, Qld and Victoria have groups with regular events for smaller (150g and 1.3kg) bots, all have groups on F-book. Bigger events with combatants Australia-wide like this used to happen 1-2 times a year but it's been 3 years till this recent one - my bots were getting restless! (sorry if duplicate replies, my first one seemed to get eaten by the algorithms)
@@slightlyevilrobotics4271 i'm in NSW sydney, do you know of any over here? i've always wanted to try and make a battle bot
Loved robot wars growing up. Never made it to the live shows but years later managed to go to a touring event and it was amazing.
Really enjoyed watching your journey and hope to see more
Yeeees, been waiting for more battlebot content!! Excited to watch
Very cool, looks like great fun after the engineering and building challenges. Looking forward to seeing the next one
Great to see some robot videos again, have missed them a lot.. WOW you created a beast there, thanks for the extensive breakdown on the build and techniques used, that was really interesting stuff.. Those battles looked epic and congrats on the 3rd place 👌
What an awesome video Angus, always love these. Massive congrats on 3rd place too.
Fantastic build.
impressive work for all the combat boots.
Thanks for sharing your experience with all of us 👍🙂
this was awesome to watch! sounds like you brought home some of that event sickness, hope you feeel well soon and keep up the great content.
That spline shaft! Tedious work, I know from experience, you must be an artist!! I enjoy art and craft projects that take patience and problem solving like that.
Awesome, awesome, awesome! More robot fighting and I love the behind the scenes breakdown of how and why!
I was there when you fought this thing and I really enjoyed watching it!
(So honoured to have my ant make a cameo appearance! Big vert, pink wheels, purple eyes. Can't miss it!)
He threw YOUR battle bot directly at YOUR camera. That's beast mode control.
Combat robots are so cool, but the coolest thing about this video is that '90s-looking hoodie 😍
Good effort! Really impressive build and video production is on point as always!
I love how you guys are keeping it clean this is what you call friends doing what they love gotta support y'all ❤️
That has to be the best video I've seen this year. Maybe the best in the last 10 years. Thank you for the insight.
Amazing video like always! Congrats on the win 👊🏼
Love the hand ground spline! True Aussie bush engineering! Brilliant.
Amzing stuff! Happy to see you challenging this area.
This was a fantastic watch. Nice job on the 3rd place win.
Amazing use of that great work bench. 😁
LOVE the self made splines as well as the saw blade recommendation! Very cool!
Awesome build! Fun battles! Great work & video.
I had a lot of fun watching the video! Thank you! 😊
Great example of TLAR (That looks about right) assembly and design.... fantastic video and totally inspiring!
Such a great competition and video!!
Thank you for posting this. Been trying to find a good video on Combat Robotics ❤️❤️
good meeting ya at the event man. Those where some good fight 🔥
It was honestly great to hear your legit thoughts about PCBway in the video instead of just being sponsored and giving an ad read, it might actually be something I will use in the future, thankyou!
So much enthusiasm about conception, construction and destruction is very motivating.
This was very neat, I hope you continue in this (yearly?) competition.
TH-cam's makin me happy with recommendations. Awesome job dude
Oh wow !! Nicely done dude !
Great work and thank you for sharing! For the anti tip feet, if you were to put a bearing under each, you wouldn’t end up stuck in place and you could use that mobility to move your opponent to a place they don’t want to be. Cheers!
Having done Vex robotics for a good like 5 years now, this build made a lot of sense to me and I liked how you made it. When you showed how the arm works I was like "yup that's how I'd do it"
Legend !!! Cheers for coming to Adelaide!!!
Great job man! 3rd place is awesome at at a competition like that. I'm going to use PcbWay in the future!
That was hilarious, I enjoyed that so much. Thanks for sharing it.
When you mentioned how hard it was to control, oh man did I relate to that! I did a lot of FIRST robotics (FTC and FRC) and they can get really complicated to figure out. Normally we set up for two drivers, but once or twice we had to drop to one for some reason or another. And man, did that suck to do!
Awesome video as per usual.
I see those synthesizers/music equipment in the background and really want to hear what you make with them :P
Plus 1 for the bandsaw tip. Even a handheld portable bandsaw is a gamechanger for building things.
Amazing! I didn't even really know this whole battle bot thing was a thing!
Thank you for making this video! The idea of hand grinding splines... wow. I agree with you that the belt has no defense. So, yea, that needs something to prevent it from being rendered useless after 1 hit. If you must stick with the saw blade design with a "lifter", you should consider a lifter that has at least 2 parallel lifters, perhaps like a fork lift, or maybe upside U shaped (joined at the ends) for more rigidity. I suspect, that 1 lifter, tilts the enemy bots more than it "pulls it up" into the blade., whereas a parallel lifter might give you better leverage.
The Locked Rotor Amps / Stalled Amps of a motor tend to be 6 to 10 times more than full load (100% RPM). So, one reason why the controller may be dying might be related to the Amperes being drawn with rapid "on" / "off" cycling. Because that's basically like several 6 to 10 time Max Current hits in a row.
Definitely agree on more of a "fork" design for stability. I was originally going to have a spatula kind of scoop, hence the name, but went with the spike due to time restrictions.
I forgot to mention... that DC motors with big armatures tend to have pretty big spike voltages due to the commutation. Consider adding flyback protection.
@@marcfruchtman9473 Yeah, we suspect that's what killed the esc but it wasn't doing any heavy lifting at the time. I'll most certainly swap to a smaller brushless outrunner for next time if only to save several KG of weight.
@@marcfruchtman9473 . "Flyback protection"? A term I've never heard before. Granted my electronics schooling is 40 years old. I think I understand what you are talking about. When you power any wire coil it builds a magnetic field of energy. (Solenoid or motor winding). Take away that feed to it, the collapsing magnetic field around the coil wants to dump current/voltage to somewhere. You don't want it to go back into the driving circuitry. So you add components to direct it away from there. In the case of solenoids, it's simple, a diode/rectifier to ground. DC motors I can see being tricky because it's not a one way deal like solenoids.
Did I get it right?
@@tigerzero5216 Right, not only that but the collapsing field can dump many times the voltage of the power source.
this is sweet. well done!
Thanks for 22 minutes with a smile in my face and get well soon 💐👍🏻
6:13 Good ol' Cut'N'Try Engineering wins the day once again! ❤🥇
Congrats on the 3rd place ! You created a mean robot ! Can't wait for version 2 !!
that was awesome! great job taking 3rd
Angus this was such a cool episode! Congrats on 3rd place, very cool
Well done man!
.....YES
A video by muse...
Keep up the interesting content maker's muse!
This video best of all year in my opinion!
That is so awesome, congratulations on the third place. And great video.
Great video. So much fun!
BLOODY AWESOME, Angus! Over the moon to see you getting back into the bots. This video easily competes with a BB ep 😃
So cool! Good job!
This is a really fun video. Love the smaller robot classes.
A tip from an experienced spanner swinger when you have a slightly loose id for a bearing a few center punch hits will help tighten the bore and hold the bearing tight
That's actually how the bearing in my truck's A/C clutch pulley is retained from the factory--a series of punched divots around the circumference of the bore it sits into in the pulley.
Totally love your build the car-nage 😉
Man the kinda people at that event sound absolutely awesome I wish I knew spaces like this in Vancouver. Not for robot fighting but with people who are cool and make things!
Great stuff. I dig it.
This was a great watch
Nice build! Grinding the spline was a good idea.
Thanks for doing something with BATTLEBOTS in it because those are the coolest things
Good job on the spline!
Sandwich: the cutting board with thin sheetmetal between. When I cut concrete, thin metal would immediately bind blades that were over %25 buried in the material to be cut. Those thin strips were jamming up 30hp saws. I think itll work. You could also try to apply the "reinforced concrete idea, and put little scraps of dangerous shit inside of the plastic if you are able to melt and recast for the armour.
Really fun bot and a cool design! My own Beetleweight bot Shrapnel Mine has a similar concept but rather than a rear hinged lifting arm it uses front hinged forks to try and expose the underside of opponents to my saw weapon.
I have the same control issues as you though. I just bought a Radiomaster Zorro TX which has potentiometer dials to set the speed of the saw and I can then use a switch to turn it off and on and the 'throttle' to control the arm position (since mine is a servo it's way easier to handle the arm though). For your needs the Zorro has four momentary buttons that may make controlling your arm easier even if it's bang-bang style and you could use a dial for the arm speed as well.
A very fun and interesting video! I hope you make more contect like this :)
Wonderful practical examples of when to print and when to CNC with examples. You might want to consider finding out how the current limiting works and design your own as the back EMF might have caused the controller to brick. On the robot, you might want to see if you have a spare channel open so you can add 1 servo to expressly lock the cutting arm and the spike at the lowest setting so you can pinch and lift during combat. It could be as simple as a cam rotated to press a spring loaded pin into the blade arm since you use a U shape around it already. Best of luck with the next round of Combat robot fights.
Oh man this looks so much fun
6:03 Absolute madman 👍
Nice build. It looks like a lot of fun.
Thanx a lot showing so much fun stuff. 😂
I mill ~ 8 ton/year of 7075, also called AlZnMgCu1,5 a good choice for max stable parts. 7075 is 550N/squareMM and you never need threaded inserts. I also like in this alloy there in no silicium, so milling cutters last 10 times longer.
Nice video. This and earlier robot videos make me to want to build at least 2 3d printed robots
3D Printing is completely viable for the smaller classes! We even have a 150g "plastic" class which is similar in spirit to the sportsman class with a very low barrier of entry.
@@moremakersmuse I need to look up what we got here in the Netherlands. Will than probably start with push bots.
Sick vid Angus.
Dear Angus and if that's not your name I apologize I saw one of your older videos a while back about g10 as a build plate and I just wanted to thank you for turning me on to the material and it has saved me a lot of heartache in my 3D printing projects PS I love your channel keep up the good work
Aaah! He's got a board with a nail in it!
Congrats Angus!
Angus this rules. Dunno if you remember, but you helped me make a sawblade wedge using a direct drive car fan motor that got obliterated by a vert spinner way back in the day. So glad to see you still kicking arse and scaring off mormon doornockers!
omg Nick! Good times that was so long ago haha. yeah we did some pretty sketchy things back then. Hope you're good?
@@MakersMuse yeah mate! Stoked you spotted this! I’m doing great, working in web development, still in Sydney, although the most I’m building these days is a mechanical keyboard haha! Always stoked to see you drop a video :)
Those sparks at 6:33 would make electroboom proud
hey Angus, quick tip for showing packages on screen. you can wipe acetone on labels to clear them 👍
Awesome! Cool knowing someone that competes in robot combat.
Nice one!
I watched a couple of episodes of Robot Wars (UK) a few years ago, but it got boring fast. The engineering choices and how well they worked, really compelling.
