drive train wearing out?

[imdunne8]

I think it is important to note a few other things -

First off, the launcher and drive motors are on separate fuse panels (drive motors on 40A maxi block, launcher on 30A). I second that the problem is not an electrical connection problem, though we are going to check to make sure when we get to Atlanta.

Second, about the turning - I would say that we encountered a 75-99% loss of turning ability at the Wisconsin regional. At the practice field, we would give the robot a 100% turn command and it would turn extremely fast. In Wisconsin, we gave it the same command and it would either turn much slower or just give a bit of a jerk, then stop.

Finally, it seemed like the robot would drive better (more like it was at the practice field) when in low gear, but it just runs so slowly that we cannot waste that much time driving around the field.

I am personally leaning toward our CIM motors going bad because our lifter, which is using the Taigene motor, seems to still be functioning perfectly. Has anyone else ever run into CIMs going bad after quite a bit (I would guess at least 15-20 hours) of running their robot?
