Hi, I just recieved my vex robotics (PIC) set. I built the tumbler, a standard robot. whenever I turned it on, it would spin up the motors, then the battery light would turn red and it would go into autonomous mode. it would then shut off, and try to turn on and have the same problem. when I picked it up, it would stop, but only until I drove it a little bit.
I thought it could be the batteries, so I changed it to High-output batteries. It would still have the same problem.
please help, wasabifan
