[Al Skierkiewicz]

From a robot inspector who has seen thousands of attachments, a mount that is attached to the bumpers that fits into/over/on the frame and has hardware/pins/latches that are installed from the top of the robot are the best. Screws/bolts that need to be driven in from the interior of the robot frame are OK but you will eventually drop that hardware in the robot and it will take special tools to install or remove the bumper system. This year had some defense but not as much as I expected. Bumpers are meant to take the full punishment another robot can inflict. Make them secure and easy to remove.
