i am driving 3x 2.4 1A motors (from electrical screwdriver) via relays (here is circuit: just i am using much more lower resistors 470Ohms.), what speed i don't know, searched for documentation but couldn't find. i will build 3 buttons to calibration mode, at start robot will go from any position to starting position. i think that's all.
