Answered: motor twitching

Just got new parts and after building the robot, connecting wires, and turning on the power, the robot starts to have spasms and twich all over the place. Pressing the button on the programming wire doesn’t do a thing and the twiches make the comtroller unsable. The problem seems to be related to the number of motors/ servos connected at one time; when only four are connected, there is no twitching, if another is plugged in while the system is on it is still ok. On the other hand when powered on with 5 motors/ servos, then the twiching occurs.

Have you changed the program in the VEX Microcontroller? Are your batteries fully charged?

I actually solved the problem, it turned out to be the batteries.

Glad you got it going…
