Drivetrain Issue

[Jared Russell]

If it turns to the left, then the right side is going faster.

If the right side is going faster even though both sides are told to go the same speed, then the left side has more resistance.

If the left side has more resistance, then:

1. Check any chains for alignment and tension (not TOO much tension!)
2. Make sure there is grease in the gearboxes.
3. Listen to each side independently. If they sound different, there is a mechanical problem most likely in the gearbox (alignment or debris).
4. Make sure all electrical and mechanical connections are TIGHT!
5. Sanity check yourself by removing the motors and seeing if they seem to match in speed when not loaded.

1726 experienced a similar problem during our early build season testing. A victor had burnt out forcing the remaining motor on that side not only to move the robot, but also to back drive the other motor. We discovered this when a student noticed that one motor was much hotter than the other. If both your motors are the same temperature then this is probably not the problem, but it's probably still worth checking.
