Meltybrain “Karoomba” spin up and calibration. 3lbs spinning at about 1000 rpm.

This is a test of Karoomba, a beetleweight combat robot, scheduled to compete in the September 2024 NHRL event. This configuration is 2lb 15.5oz and its 14 inches from impactor to impactor. This is not the final configuration, but component shipping takes forever and people were asking me for video. TIL that ground in the recycling area of my apartment is too rough to get good control. [Edit: Or is it?] The only areas of the body with abrasion were the parts right next to the wheels, and that seems to be from crossing between the concrete slabs in the floor. [Edit below] On rewatching, it looks like the abrasion was because the bot is twisting when the motor pulses for translation. The actual configuration won't have such enormous motors (they're currently 3548 1500kv) or such enormous ESCs (currently 80A). Perhaps that will stop it twisting so much? If I remember I'll record the next one in slow motion. I've patched the meltybrain code on the Teensy for the next test to indicate when the motor is firing (using the red and green LED channels). It's only a thousand or so RPM so it should be slow enough for my phone to capture it in slow-mo. (Two frames per rotation isn't enough to see what's going on properly.) I still need might need to find a better place to test it. [Update 2] The slow motion video was even worse than this because I put the robot further away. I've got a couple more ideas left for getting rid of the wobble.
