I built a sumo robot for BrickFest '04. Oh, sorry, that's right, can't mention
sumo on this channel.
Ok, I built a vanilla robot that happened to use two RC motors. First time I
tried it on the kitchen floor, it damn near killed the cat. Turned out it went
much too fast for the RCX to react to sensor input and kill the power.
I used 9v (6xAA) battery packs to power the motors one per each and used regular
gear motors to drive cams to operate the battery packs' buttons. Worked great!
As long as you're not a cat.
I ended up gearing the motors down to reduce speed rather than increase torque.
But you're right, the overload trips will go off in the RCX if you try to drive
these motors directly.
