- This video covers Division's battles against fellow Battlebots competitors from the Ribbot and Pain Train teams. Division is my oversized 3-pound vertical spinner robot, known for being one of the most dangerous and unpredictable robots in the field. Watch Division through this month's Norwalk Havoc Robot League (NHRL) Tournament, and the lessons I learned along the way.
The May 2021 Norwalk Havoc tournament was held with strict COVID protocols including a mask mandate, and with great air circulation throughout the venue. In addition, I myself am fully vaccinated with Pfizer and still wore a mask and practiced social distancing where possible.

![Can My Custom Weapon Motor Survive? [Mass Destruction 2023 Recap]](http://i.ytimg.com/vi/LdkIH0p8NEM/mqdefault.jpg)
i loved the cool trailer at the beginning, it was really epic LOL
thanks for inspiring me to come last Saturday to compete, I wouldn't have gone if I hadn't found your TH-cam channel!
I love the sportsmanship and camaraderie at these events! Since you like the Giant Gyroscopic Weapon of Doom, have you considered building a Droopy-style gyro-walker? Or maybe a Wrex-type version with a vertical spinner that "walks" by turning it from side to side? The extra weight allowance could make that weapon even scarier, assuming the rules would allow you to add more power or mass to the spinner(s).
Division is always fun to watch, even if it doesn't always get along well with physics. :) Commentator: "Division is showing some control--" [Division immediately starts flying around the box like a shuriken that wants to attack the whole world] :D
Making something kinda like Droopy would be cool but it is an incredibly hard thing to do. Tommy Wong said he spent 9 months working on it before it would even move properly. I don't want to just copy his design either, I would need a unique take. So I'm focusing on Shrapnel Mine for now
@@JustCuzRobotics Cool! "Shrapnel Mine" is a great name for a bot. I look forward to seeing it do its thing. :D
Good shit, Seth! Love these videos. Can't wait to see Shrapnel Mine in action!
Thanks!
nice intro! working on making my own beetle weight bot right now. love the vid
Thanks!
Great intro! I'm happy to see that hinged wedges have potential! great recap!!
Even though it might not have worked to well but the forks look great and have protential like rotator wedgelets they used in season 4 then upgraded to season 5 which were insanely good
Loved the video as usual seth :)
TPU hates hot glue. TPU loves super glue.
Those were some great fights! I love watching your design evolve after all this time! Can’t wait to see what you add to the next revision.
Have you ever considered adding rigid forks out the back of Division that sit just a couple millimeters from the floor? Watching all your fights, I keep seeing Division getting thrown backwards by its own hits. The vertical forks definitely helped in your fight against Blackbird, but it looks like you could still do a little more. Maybe something like rear forks could help the robot “plant” itself into the floor when it delivers a hit, so that you can both hold your ground and transfer more energy to your opponent.
Keep up the awesome content!
I think having forks at the front and the back would make it extremely hard to self right in the event the bot still flips onto its back somehow, as there would then be no way for the weapon's gyroscopic forces to pivot the robot forward onto its wheels again. That's the reason I have triangular bits out the back now, to promote it rolling forwards onto its wheels. I also have a piece of material that's hard to see which is under the robot and touches the flood whenever it kicks back, which does a little bit to counteract those backwards lurches. But there is only so much I can do when each hit is at a slightly different angle. Some push the bot almost straight back, others downward into the floor. It may be worth experimenting with in testing though.
I realy enjoy your videos a lot! It is so nice to hear your thoughts and see the results, hear what failed and your guess why.
I've got at at least 50% of what I know about robot fighting from you as a source., and I am just a viewer of the sport. But what about no side Wegdes/forks at all? They are mounted on the side and when hit, put a lot of stress on your sidemounts. Is that worth the benefit? What is the real benefit? Of couse you could get under the opponent or block them some way, but you can do that with your middle forks as well and then you connect with a hit and do destruction, what division is all about. My thinking is just, leave that potential weak spot of and go more for yolo, one hit that kills them all style
Thanks for the kind words! Like with the horizontal config I need some rigid forks to prevent the robot from faceplanting under the gyroscopic forces upon spinning up the weapon. However you are right the cost is not worth the benefit from the side forks being also made of hardened steel.
What I should be able to do is make similar ones from thin flexible TPU or UHMW plastic so that they will simply flex out of the way when hit sideways, but still act fairly rigidly when the bot tips forwards to resist that motion.
@@JustCuzRobotics One thing that crossed my mind in regards to TPU. I dont know if that would work, but hear me out. What about you make a Print with two extruders, one rigid tough material, Nylon, ABS or whatever you use and TPU. Inner and outer walls rigid and the infill with TPU. Maybe it will not work as easy as that, and you need a shaped connection between TPU and the rigid stuff. The advantages I would see are, you can better mount and glue the part and shocks to the Part get dampend a bit. Maybe worth to try it on your wheelhubs, what do you think?
Unfortunately I don't have access to a printer that has dual extruder and I don't want to spend $1000 on one. However I did hear from Calvin Iba (Lynx, MadCatter) that he prints Nylon inserts to epoxy into TPU prints to accept threads which seems like a great thing to try out to me.
One word for this video: BOOM
I want to do this when I graduate
Why wait? I started as a junior in college. Several others start in High school or even earlier!
@@JustCuzRobotics I am a freshman and we are a family of 7, so it is kind of busy and I am trying to plan first for the uncertain future
@@JustCuzRobotics I also have a very strict mom and she won’t even let me watch BattleBots
That is very unfortunate, but hey, at least you have TH-cam :)
@@johnpaulrodriguez1469 Why can't you watch Battlebots? It's a great show.
Great intro !!!!
Thank you
I like the intro.
Thank you!
Have you tried ninja flex armadillo. It's pretty stiff tpu and seems reasonablely priced. May be a better hub material while still having that you vibe. I had a maker box sample and it seems lit
I use TPU hubs just like this on my 1lber. Print the holes in the hubs to a smaller diameter than the drive shaft, and use alcohol as mounting lubricant. It cleans both surfaces, then evaporates, leaving a very good friction fit. The only issue i ever run into is when i dont follow the alcohol installation process, then they will slide right off.
Great idea! I may try that sometime soon.
@@JustCuzRobotics The hubs also utilize a mushroom shape for wheel retention. Its a simpler 1 piece design, and i havent had a wheel slip the hub yet. Again, just print it to compress fit and it holds really well, no ribbing required.
Heya! Honestly can’t say I like the new intro in particular - it kind of spoils the direction that fights are going in, even for a moment, and half the fun in these videos (at least for me) is you discussing the type of bot your opponent is and breaking down your win con before you actually begin the fight. I want to go in to the fight when strictly the information you’ve given me without knowing the largest collision or event already, you know?
That's definitely fair. Sadly the fights were so short this time it was hard to show something happen that's didn't give much away. Hopefully I'll get more/longer ones next time!
You need some "wheely bars" to stop it from launching itself back head over heels every hit.
I think that wouldn't really stop it from launching backwards, at best it would keep the bot upright. But it also makes it much harder to self right if it does flip over, which is a big tradeoff.
@@JustCuzRobotics
Understandable, have a great day.
I didn’t realize how quiet the weapon on division was until bx11b stopped spinning
Yeah it doesn't have to cut through nearly as much air, plus it is running at less than full speed a lot of the time. Those beater bars always sound like their bearings are about to explode.
Music is kinda weird but I dig the intro
Do you have the weight to add some rest forks to possibly prevent or at least medigate division launching itself across the arena. It would probobly be even more reliable than it already is. Also I would love to build an AW or BW. Is it actually posible to build an overhead tribal in this weight class
You can build whatever you want as long as it's under the weight limit and conforms the the other event rules! Check the link in the description to see the rules for NHRL, or Google the SPARC rules for combat robotics for a more general set.
Whiplash used rubber bands to make sure their wedgelets stayed as close to the floor as possible. Maybe you can do something similar for yours? Rubber bands or a metal spring or something?
Maybe. I think gravity will really help if I just stop them getting locked upwards though.
I think Endgame has springloaded wedgelets and it obviously worked well enough for them.
I'd love to try this at some point but the german scene is basically non-existent.
Same I’m from Australia and I’m unsure if there are events here other then ARC in Adelaide there might be one In Ipswich but I am very unsure
@@kizzyau1306 I'm surprised at the lack of university teams. You'd expect every uni with engineering students to have at least one team.
There are a ton of university teams here in the states but they aren't all showing up at Norwalk for some reason. Many have been at Motorama however
Same problem in Denmark. I have sooo many old fpv drone parts that is perfect for this.
@@kizzyau1306 what state are you in? I couldn't find anything in NSW and wanted to get into the sport recently. My current plan is to talk the University of Newcastle into sponsoring a competition once I have a bit more practice and convince a few more alumni to participate.
