Sure. During auto the robot would go through the low bar, and then attempt to back over it. If our alignment was off, when backing up, the robot went in at a slight angle and was pushing against one of the side supports for the bar. The motors proceeded to run while the robot was pushing against the support for a good 5-7 seconds, causing the gears to grind. This happened once or twice until we dialed in our positioning. For context, this gear is part of the third stage on the 2 CIM ball shifter. It actually drives the output shaft.

There are so much more things to be worked on and are more beneficial to FIRST and FIRSTers than green dots by someone's name. - tiffany34990 [more]
