: Joe,
: Every year my team has produced a drivetrain that has had a problem, the problem is that when we are driving(not that long of a period) maybe 5 minutes oneof the motors cut out and like if you wiggle the joystick it will come back. :

Hey,
My team has experienced the same problem, assuming you are using the BOSCH drill motors for your drive system. Two major faults with using these motors lies in how they are supposed to be layed out within the drill and how you lay them out on the robot. The first problem, is that although the motors appear to be "in" and attached to one another, if one side should slide out it causes the motor to disengage from the gear housing. My team uses 1/8" lexan as spacers underneath the motor to keep it inline. A second problem is the high/low shifter on the gear housing. When operating for over about 2 minutes it moves enough to slip in between the high/low gear. It is then unable to move and the motor spins but nothing else does. For this my team either uses a zip tie to hold it in one gear, or we use this year secret weapon... Hope this helps.
-Rc
