My team has built a 6m drive that is 257 rpm (geared down) and as we were testing it we found that two motors (one on each side of the drivetrain) was using less power ( I am looking at the wattage) than the two other motors on the gear train, I am unsure as to why. I thought it could be friction but then all the motors would be using the same wattage. The two motors that do seem to be functioning are using 3-5 watts which in turn heats up. I have tried trouble shooting by switching brains, motors, switching cables, and rewriting code. I hope you guys can help!
I’ve had this problem before and it has to do with using a percent based drive code. My current theory is that when the motor uses it’s internal PID small differences in motor speed cause the motor to use more and less power than they should. I would recommend looking at the relevant documentation for your coding platform to find out how to switch to a voltage based drive system or using the search bar in the forum.
