R404       *Bumpers must come off. Bumpers must be designed for quick and easy installation and removal to facilitate inspection and weighing.

R407       *Bumper weight limit. Each set of Bumpers (including any fasteners and/or structures that attach them to the Robot) must weigh no more than 15 lbs. (~6 kg).

R401       *Bumpers should protect all corners. Robots are required to use Bumpers to protect all outside corners of the Frame Perimeter. For adequate protection, at least 6 in. (~16 cm) of Bumper must be placed on each side of each outside corner (see Figure 9‑3) and must extend to within ¼ in. (~6 mm) of the Frame Perimeter corner. If a Frame Perimeter side is shorter than 12 in. (~31 cm), that entire FRAME PERIMETER side must be protected by a Bumper (see Figure 9‑4). A round or circular Frame Perimeter, or segment of the Frame Perimeter, is considered to have an infinite number of corners, therefore the entire frame or frame segment must be completely protected by Bumpers.

G103       *Keep your Bumpers low. Bumpers must be in the Bumper Zone (see R402) during the Match.
