[Tristan Lall]

Design your bumpers so that each segment is removable by one person in less than 10 s, yet won't shift or fall off during a match. This is easy using a locking pin system (if you pay close attention to hole tolerances and alignment), but a bit harder if using threaded fasteners (try wing screws and threaded inserts for woodworking).

For bonus points, consider using the bumpers as robot structure (plywood can be quite strong). In that circumstance, a little extra effort to remove the bumpers (like 60 s per segment) is perhaps justifiable.
