Well I know this is not a Eboard, but I designed this robot with most of the information I got from trolling around this forum, so i thought i’d share.
First off, what is a sumo robot, well in a nutshell, you take 2 sumo robots, stick them in a dohyo (arena) last one standing in the dohyo wins. The catch is, robots must be autonomous, max size of 20cmX20cm and under 3Kg. No circular saw nor flame throwers. Oh and the Dohyo is made out of steel, so the use of magnets to increase your down force on your wheels is encouraged.
What so eboard about it? Well it’s wheeling a pair of VESC, TB’s 5065 170Kv sensored motors and a 3:1 pulley reduction. Wheels will be 2.5", shore A60, casted by myself with smooth-on vita flex 60 polyurethane. Powered by 12S lipos.
for the moment I only have 3D renders of the whole thing, all the parts are being manufactured and will be receving them in the next weeks. I’ll post the progress of the build.
under, showing off the magnets
The main PCB, where all the sensors and VESC interface, i’m using the Teensy 3.2 for a MCU.
Power input pcb, same as vedder’s anti spark board, but with 3 XT60 connectors to put the lipos in series.
