R105      ROBOT extension limit. ROBOTS may not extend more than 12 in. (~30 cm) beyond their FRAME PERIMETER.

Figure 8‑2 FRAME PERIMETER extension

P1189#yIS1

Teams should expect to have to demonstrate a ROBOT’S ability to constrain itself per above during inspection. Constraints may be implemented with either hardware or software.

See Section 7.4.3 Game Rules: In-MATCH: ROBOTS for height and extension restrictions for various areas of the FIELD.

Rule R101
R101      *FRAME PERIMETER must be fixed. The ROBOT (excluding BUMPERS) must have a FRAME PERIMETER, contained within the BUMPER ZONE and established while in the ROBOT’S STARTING CONFIGURATION, that is comprised of fixed, non-articulated structural elements of the ROBOT. Minor protrusions no greater than ¼ in. (~6 mm) such as bolt heads, fastener ends, weld beads, and rivets are not considered part of the FRAME PERIMETER.
Rule R102
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 FRAME PERIMETER, with the exception of its BUMPERS and minor protrusions such as bolt heads, fastener ends, rivets, cable ties, etc.
Rule R104
R104      STARTING CONFIGURATION – max size. A ROBOT’S STARTING CONFIGURATION may not have a FRAME PERIMETER greater than 120 in. (~304 cm) and may not be more than 4 ft. (~121 cm) tall.
Rule I105
I105        *Don’t exploit re-inspection. Teams may not use the re-inspection process in I104 to circumvent the weight limit in I103.
