Hello all,


On our robot we have run into an interesting problem. We are running the kit of parts frame from AndyMark AM143U. We have the standard gearbox (ToughBox mini's) hooked up into VEX 217-2000 12V Motors.

When we drive the robot, one side spins faster than the other. Which in turn leads to our robot not driving in a straight line, even though the joystick is pressed into a straight line. So far, weight is pretty much evenly distributed. When we have our robot lifted, and the joystick pushed 100% forward, our robot will run for about 10-15 seconds before one full side stops moving completely. Our battery voltage drops from 12.5 volts to about 10.5-9.5v or so during the continuous run. Our robot registers no error codes during this time. I have a feeling that the problem is electrical, but I am not sure where to look. Any suggestions would be greatly appreciated.

Thanks,

Joe
