Re: AndyMark Parts Feedback 2015

As an LRI, I came across several teams that were getting hot motors and/or voltage drop outs. A common issue I saw was:
Kit bot modified to 6" wheels with no other mods. The effective free speed for this arrangement is quite high (something on the order of 20 FPS). This lead to a lot of hot motors.
I also helped a few teams that had placed a gear backwards in the gearboxes. There is a small offset that helps keep the gears from dragging on the housing. this drag resulted in hot motors as well. It might be good to add a current check on blocks for a chassis to see if you have un-necessary drag. this can be done with the PDP board and your laptop. Might be good to add a diagnostic tool.
