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.

R401       *BUMPERS all around. ROBOTS are required to use BUMPERS to protect the entire ROBOT PERIMETER. Gaps of less than 1 ¼ in. (~31 mm) between adjacent segments are permitted as long as all corners are filled per R406.

R105       ROBOT extension limit. ROBOTS may not extend more than 1 ft. 6 in. (~457 mm) beyond the vertical projection of their ROBOT PERIMETER.

R405       *BUMPERS interact with BUMPERS. All BUMPERS must have padding (per R402-A) supported by backing (per R402-B) entirely filling the BUMPER ZONE, a space between 2 ½ in. (~63 mm) and 5 ¾ in. (~146 mm) from the floor.
