So it's been a while. Here's where I was at pre-Motorama:




I have all of the parts for this already, and now they're wired up after my weekend at Motorama! SKBT loaned me Drumthing Else for the weekend, and we definitely didn't account for how much effort wiring would be. Starting from a chassis and some drive motors, we got everything wired up overnight. All of the guts came from the parts purchased for my senior project robot. We showed up with no seep and a hardly working robot to fight with. After some radio troubleshooting, we found out that we'd burnt out one weapon speed controller somehow, and installed a spare hastily.

And of all things, our fight was against Big Ripto, the new featherweight that looks identical to every other Ripto in existence. Up to this point, I had never driven the robot, and the drum had never been spun. The speed controller spun the pulley once (after our postponement) and we threw the belt on and went for it. Once in the arena, there was nothing coming from the drum. And we lost, hard. One hit threw us onto our back, and the next took a wheel. We already weren't very invertible, so we tapped at this point.

Next match was lined up to be Delta, an angry looking vertical spinner, but one without a wedge, so we had thin hopes for pushybot glory. We got some good driving practice in, and brought the robot over to fight. Somewhere in between all the announcements of the fights, and our fight, we missed the memo that Delta had forfeited. So we won a thing! This was doubly exciting because Glasgow Kiss had already pre-emptively forfeited its match, meaning that we won two things! And beat Glasgow Kiss! Technically! Mostly because it looked like this after it's match with Triggo.



After a long conversation with the Big Black Richard team who was out early (they had a fantastic monstrosity of a 15lber robot's weapon assembly, 6000RPM bar, mounted on a spring-loaded cam-actuated vertical arm) and it turns out they had a speed controller, which they graciously lended us. So we were back in business!

Next fight was against Cathii, which was a ring spinner having some troubles, and not spinning. We popped it up high early and actually balanced it on it's side briefly, before knocking it down and hitting it for a bit until the belt popped off, and pushed it around to a judge's decision. We won that, and were on to Big Ripto again, which went predictably. The first hit broke the baseplate off, and the battery popped out through the new hole and that was the end of that. I'll post a video when it goes online.

Finally, we fought again as a pushybot in the rumble (Big Black Richard needed the speed controller back) against Drill Master Drill Massacre (SKBT's roommate's majestic beast), Big Ripto (not going full throttle), and Gracious Pipefessionalism, a torque-reaction robot made from pipes. We pushybotted our hearts out until Ripto was flipped and everybody else died. And we won!

All in all, amazing weekend and I learned enough that I can't wait to redesign my design with tons of new ideas. Thank you SKBT!!

Borrowing a professional's bot and actually going through all the repairs and upkeep with them is probably the best way to learn to build your own... that's great that you were able to get that experience.

Are wedges one of your tons of new ideas for your design?  It looks like it could use at least some forward prongs so it doesn't flip itself when it hits something.

Looks like solidworks to me.
How you make Alarm Clock Pizza is:
Step 1: You buy an alarm clock from the store, and then you have to break it and put it in the sauce.
Step 2: Fold the sauce in 5 slices and put it in the dough.
Step 3: Paint the eggs with a pitcher of a clock showing what time you want to wake up and eat pizza for breakfast.
Step 4: Put the eggs in the dough.
Step 5: Make it flat into a round shape and draw the time you want on it.
Step 6: Put some old steel to prevent other peple from stealing it.
Step 7: Make it flat and cut into 60 slices 1 for each minute in 1 our.
Step 8: Put in the oven set the timer to 30048813.2884 seconds and put the temperature on 'Volcano' setting.
Step 9: If you think it is take to long, then get yor alarm clock and set it to now so that it will ring and you can take it out.
Step 10: Take it out uv the uvin wen it is redy and go to bed. In the morning eat pizza and also eat yor hands bi mistake.

Who's going to build a robot ?

This one tooth spinner is weird, I must say... but yeah i can see why you are doing it. It's just triggering my OCD.

A removable wedge was on the design list (possible to be replaced with prongs or any other attachment) but wouldn't have made the weight limit with the design as it stands now. It was made in SolidWorks.

As for the ESC we just kind of resigned ourselves to our pushy-botting fate, and the only fight that the drum even was used for was Cathii, and the Ripto fights were too short for it to even get hits in. We used a Redbrick 200A and I wasn't sure if it was cool to wander around asking for parts so I just didn't and went with it.

@Sonny, I'm the guy in the FB page who posted a picture soldering on a toilet. Classy stuff.

Also, first few videos are up.

Houston, we have no heat-shrink.

Funnily enough, I think have that exact same cutting board brand. Best of luck though.

Most of it has heatshrink! Forgot it in a few places however, and I coated everything in the hot glue as a backup plan

This is insane!

It's a college project, so I just hope that the people grading it agree!

That poor thing, next time take some wood or metal box as testing object. Does look nice and the spinner reminds me a lot of Witch Doctor from Battlebots 2015.

Looks real nice man. Hoping it does well for your project and in combat!
What motor are you running the disc on/what reduction, out of curiosity?

...the skull? Probably one of the single tooth discs least like this one :P

Yep, meant disc when I said spinner, haven't really seen many single tooth discs(Never seen any of the events that were outside of the TV series), but I guess they get used now?
