Bumpers

[buildmaster5000]

In the past, we have had vertical pieces of 80/20 on the corners of the robot. We would put screws into the back of the plywood, leaving the heads exposed in order to slide down the raceway of the extrusion stock. It is admittedly a pain to get right at first, but they slide off so easily that I definitely feel that the effort up front is worth it in the end.
