This is our first post. We need some advice.
We want to make a 3kg sumo robot with Arduino UNO. We have been doing our first programing experiments with temporal full-rotation servos, and now we wan't to choose some good ones and buy them.
We know most sumo bots use gear motors, but we would have to learn how to program them, and we have seen some sumos with servos, the problem is the torque ( we don't know if something like 15kg/cm is too much, too litle or what) and the rpm, since servos usually are slow.
