We (dukes #991) at the elimination rounds in phx stripped out bb gearbox plate out.
We had the stock plates and during lunch I noticed that the drive shaft turned ¼ turn freely. The motors are in the worst part of the robot to get to taking them out would take at least an hour. The team captain said “lets just run with it” I agreed, and for two matches it did fine until our drive wheels became “spinners”. Needless to say we had to dropout since we couldn’t fix the problem in time. And yup the output plate was stripped crappy gearbox!@@@
the gearboxes's now make nice gyroscopes.
