R408       *Weight limit with BUMPERS. The total weight of the ROBOT (as described in R103) with BUMPERS must not exceed 135.0lb (61.23kg)

R409       *BUMPERS should be passive. BUMPERS must be fixed relative to the ROBOT PERIMETER. BUMPERS may not contain any moving elements (beyond compression and flex of BUMPER materials) or electrical elements.

G410       *Keep your BUMPERS low. ROBOT extensions may not interact with the carpet, BUMPS, or TOWER BASE such that the BUMPERS are lifted out of the BUMPER ZONE (see R405).

R102       *STARTING CONFIGURATION – no overhang. In the STARTING CONFIGURATION (the physical configuration in which a ROBOT starts a MATCH), no part of the ROBOT shall extend outside the vertical projection of the ROBOT PERIMETER, with the exception of its BUMPERS and minor protrusions such as bolt heads, fastener ends, rivets, cable ties, etc.
