Bumpers? Reversible or not?

Drill a hole, drop a pin (assumes you can attach your bumpers by pushing perpendicularly against the robot frame).

2019 bumper

We had little C brackets on the bumpers, and a 1x1 extrusion bar on the frame. The pin prevented the bumper from getting pulled out. The C bracket prevented Y axis movement.

We went with latches in 2020 (as seen in 2363’s video) and i agree that there were some problems if you didn’t have the precision for it. One of our latches was misaligned by a slight bit, and required extra force to unlock.
