I didnt realise at the event you had the 3d printed gear, held up great by the looks of it. Very happy that i got that slowmo shot of the motor ejecting itself from the bot and the fire, makes for a fantastic highlight
Obliterator hits *hard*. Against NC a few years ago he hit the back corner so hard that in one hit he punched though 2 pieces of 6mm bis400 angled at about 45 degrees. He pushed the corner in about 15mm and cut out about a 1/2 inch cubed chunk of steel in one hit. It's the only robot to make a hole in NC in a decade of competing. For those outside the scene NC has won 3 championships from memory and placed in a few more. Great to see Obliterator in good hands. Hope to face it again in the future ;-)
@@Loebane My robot, called NC for Not Cobra. Cobra was another of glens robots that I was inspired by for the build. It is probably one of the oldest bots in the competition these days. On par with bender and some of the other artful robots Garry from victoria made. Well, except in the "artful" department. NC is just a wedge made of one piece of welded steel for the shell and some high powered drive motors. It wins competitions by not dying and bouncing other robot off the arena walls. It ran for a decade with nothing much more than cosmetic damage. Obliterator very nearly obliterated it ;-)
Or, you could nerf it in the software... Motor controllers can regulate RPM... So buy having the weapon be overpowered, it can reach Max operating RPM quickly without going over.
I'm really impressed with the quality of the part. That level of metal printing being available so readily is going to be really useful for a lot of small/hobbyist projects.
I do this with racing/FPV drones - they're meant to be flown, crashed and then rebuilt! The absolute carnage that sometimes happens is part of the hobby 😂
Wow! that held up surprisingly well for a printed part, even with it being tool steel I would have expected at least one cracked tooth Looks like the event was a lot of fun, shame I couldn't make it, hopefully next year
We are looking forward to seeing that duel undercutter meltybrain with squeaky hammers you made from an ssp kit 😂 . In all seriousness I would love to see Annie fight Derive. Dunno if those forks would last long against her... do you have an 30lb Annie?
always lube your gears! sorry I'm obsessed with lubrication :P this is really cool! I'm looking for an excuse to order printed metal, but I doubt I can afford it either way tbh!
Those receivers the MT12 came with are FrSky D8/D16. Something I had to dig for because it nearly screwed me over at an event was FrSky D8 does not failsafe but D16 mode does. That's why it didn't failsafe.
I don't think vacating the room is going to help if you don't have brick walls - lol -. I would weld up a 6-8mm steel box to spin that up in. Vertical spinners have the advantage because they are pressed to the floor in an impact, while horizontal spinners take a lot of shock load in an impact.
Use a double sided weapon and that way you will double the amount of hits and you will also get a balance like Gyrox. The more symmetry there is, the more stable a robot will be
Absolutely, it's why I wanted to use the original motor initially - but the geared outrunner still spun up fairly quickly (I left a 2second ramp in the controller to prevent some shock loading).
Has anyone tried defeating that kind of bot with the garments used to protect you from chain saw injuries? It shreds and strings bind up rotating mechanisms.
yeah anything that intentionally entangles isn't allowed, but bots often get hung up on shrapnel... Happened to me several times, need more ground clearance!
Nice to see metal printing is starting to achieve really useful accuracy and surface quality. What is the cost of something like that, is it cheaper to print it than CNC-machine it?
The blade is very heavy and spins fast so there's a lot of stored kinetic energy which will all be released on the target upon contact so yes, the momentary force is huge. Of course it will lose a lot of that energy when hitting something and needs the motor to "recharge" the weapon for several seconds before the next strike, it's not like it can do a continuous "cut", that would require a lot more power than can be fitted into the weight limit.
Thank you for bringing back combat robots to the channel. I'll second your recommendation to check out the broken link channel. His design videos are [chef's kiss], and most of his designs are downloadable so you can see how he thinks and play with his designs. Ive already 3d printed and assembled working 150g versions of derive and subdivide. Amazing channel and it deserves way more subs than it has.
I really enjoyed your video and love Obliterator! We used to use the Aria 70A ESCs on our bot. They initially looked good in the test box, but they cut out in every fight we used them. We did some exhaustive testing on them in the test box and decided they just couldn't be trusted. Telemetry showed they didn't cutout due to over current or over temp - it was a mystery. We were using blheli, and I know you are using AM32, so your experience may be different.
Someone else at the event was using the aria 70a's on 8 cells and had no problems (!) so I wonder if it was just a bad batch?? For me, the little voltage reg and diode blew. Maybe from the braking setting, but as yet it's also a mystery. Annoying.
I remember when it was Decimator (Unless this is a rebuild/upgrade/new version) - Came to the UK and ended one of our robots for the entire event in one hit... Shame it was also 10 seconds into our first fight.
make more cockatoo videos 😡😡😡😡😡😡 your the only one making them here and im like without entertainement for so long since they are the only videos that TRULY entertain me, i still love ur channel and vids btw
I had a really smart idea for Pancake. Maybe build a second version or entire new robot with the same concept but with no wheels. Only using bristle drive cause its weapon is so powerful. Kinda like Depth Charge from NHRL. Anyways have an amazing day and stay battling folks From A Fan NerfFan007 (Team Nerfybotics)
Nobody will ever build a motor for YOUR needs only, they probably laughed their asses off. I work in automotive manufacturing and we order hundreds of thousands of motors per year and they still do not make them for us xD We still have to choose off the shelf. They are selling millions of motors they don´t care if you need 10.000 of special ones or so, they will tell you to fuck off and look somewhere else then.
Always feels kind of surreal when a big RU-vidr shows a place I've been to (that road from Sydney to Newcastle). I live at the very top of NSW so I don't go to Sydney often but I've been there enough that the road is quite familiar. Maybe also because I was there in the few days before Christmas.
Working on it, but the Aus robot combat scene isn't supported by a giant cooperate entity and polycarb is crazy expensive now... the club can't afford it as yet.
Yes absolutely, but it can lead to other issues and needs quite fancy controllers or guess work on the transmitter end. Also easy to "cheat" the test, though I don't think anyone in the comp is that dodgy.
I have no doubt you could've taken the win if you had better piloting skills. You had serious problems controlling your robot, controller problems not withstanding. If you could match the level of control Derive had on his it would’ve been a much closer fight and you could've come out on top. Then again, it all comes down to luck when your robots are this well designed. Good luck next time, Angus.
Exactly, if he was experianced at this weight and was more used to controlling it, getting out of the way, moving around the arena to allow the spin up to reach potentichal etc then it would have been closer. He just needs practice. I'd recommend to just go somewhere that is open and practice slarlms, large U turns etc, even have another small robot driven by a friend/family and practice getting behind it, anything that helps to be a better driver. I do this sometimes on my motorcycle and I'm a far better rider since I started that than I did of 10 years of commuting.
I didn't watch much combat robots before, but for the first time, when I saw James controlling the robot I can tell he's very good at controlling it!! He almost never let your spinner face his robot.
Keeping the mass, or even increasing it (since with a larger pulley, you should get more torque) on the weapon/blade, while reducing the length of it should buy you some reduced tip speed.
That's incredible how well the geartrain handled the impacts, including the 3D-printed gear assembly! If it broke after the second fight, that would have been impressive but the fact that it handled all that and was ready for more is absolutely amazing. It is nice seeing commercial services offering more "engineering grade" materials that may not be cheap, but it is still way cheaper than having a machine shop produce them!
Would like to see Angus do interviews and commentate on Battle Bots, think he has the perfect personality, enthusiasm, and charisma to bridge the gap between technical aspects/people and the entertainment side!
Your video's always make me wanna make stuff, but im feeling a little burned out on 3d printing at the moment after months of repeaded issues with my printers. Kind of want to get rid of all of them and get some actual decent ones to start back up again with less of the hassel that comes with them
get a prusa - i was to rejoiced after replacing my ender 3 which now im converting to EDM haven't had a print fail in 3 years (apart from when the bed was dirty from my grubby fingers and print detached)
?you seem to have way too much fun, could you make you bot more automated? The slowest part of those "toys" is the human component. Ha 👍✌🖖🥃 thanks for the channel.
Sometimes I forget how much more destructive American and Brazilian bots are simply because we have less laws and safer cages. Obliterator shows what one of these destructive bots built with good old Aussie reliability can do if they were less restricted
I would design my robot with a spinning blade … just long enough to cut those rubber belts spinning the main blade on that design, above & below your blade. 😎
Shame about the pulley trade off, that spin up was so much faster with it. Is there a rules acceptable electronic way to limit the rpm? Would be nice too if there were the funds for a more durable cage, to get the spinners at their full destructive potential!
How come you used no lubrication on the spur gears at all? I'm surprised you didn't enclose them and at least dress them with a thin coat of grease. Gears hold up to a lot more abuse with an oil film in between the teeth, I'm impressed at the condition after the fights.

I have never understood why any videos have a warning about loudness. It's been several decades since video cameras didn't auto-level the sound to prevent hearing damage.
What about making a larger wheel by hollowing out the inside have the wheel go around the whole bot and run on bearings. Also maybe tilt it a bit so the front is a little lower and the back is a little higher. The wheels of your butt would be inside the outer ring of your blade You're basically getting a larger diameter with a hollow center.
I wonder if a CO2 powered cylinder for getting a bit more spin into the blade early on would be within the rules, though ig its always possible to overcomplicate it and temporarily make the blade itself into a gigantic rotor
@@MakersMuse yes, i have to dig into the EdgeTX thing. I got the MT12 because of ELRS, 16(32) channels and the hope i can re-use as many of my old recievers as possible, with the 4in1 module.
If all goes well then today I'll be receiving my Aluminium 3D Printed Sprocket Wheels for my E-100 ( ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-l3_RcOU3zo0.html ) as a replacement for the currently only SLA Resin 3D Printed ones I did myself. So far, the SLA ones haven't broken down but the torque coming from the Gearbox Axles is basically just begging for the Keying Feature built into them to be stripped since the Model weights like 6kg and the Tracks with their aggressive Cleats provide like way too much traction on anything that isn't hardwood flooring.
I've been a fan of BattleBots ever since the 2000's, and when they brought it back in 2016 I was stoked. I've always wanted to build my own combat robot and compete. It takes a lot of skills that I don't currently possess but would love to learn. PLEASE keep making combat robot videos 🙏
I'd love to see something like creator clash for robot fighting. Maybe 120g class to keep costs and time commitment down. You, William Osman, Peter Sripol etc.
Amazing, that 3D printed part withstand robot battle! 👍 Obliterator lost battle, but in spectacular way, spitting out his drive motor and catching fire..
They need to allow netting. Constant spinners are boring and only viable because a simple net is not allowed. I don’t watch robot fighting because of these low effort spinners.
If you allow nets then literally the only viable weapon is a net. Also if you think a spinner is low effort then please build one and win everything with no effort
