I have been having problems for the past couple of days with my teams robot stopping after about 4 mins. Today I checked the brain logs and it’s telling me my drivetrain motors have been overheating. I haven’t been able to fix it yet. I have been working on this problem for about 5 hours now. We have a competition in the morning so I’m planing to pull an all nighter to try to fix this problem. Does anyone know how to fix this or have suggestions on how to fix it?

What kind of drive train are you using? (What type, wheel size, gear ratios, etc.) The most likely causes are either too little torque or too much friction. If your wheels should have enough torque, I would recommend trying to get your drive train wheels to free-spin (out of the motor) for as long as possible.

We are using a H drive with 4in wheels, 3:2 gear ratio, 4 green motors running at 100%.
Well now I’m curious. What does your H drive setup look like with only 4 motors? Or does that 4 exclude the strafing motor?
I recommend going through the devices menu and checking each motor individually for friction by seeing how many watts they are using.
I’m sorry, our builder just told me it’s not a H drive idk what it is then. Here is a link with pictures of our robot:

I have drilled the bearing so the axle won’t be stuck on the bearing.
Idk if this matters but I replaced all the motors with new ones and replaced the brain 2 time and replaced the controller.
Check the wattage using the devices menu. Also, check your gears and make sure they are meshing correctly and don’t have too many damaged teeth.
