R410      *BUMPERS must be supported. BUMPERS must be supported by the structure/frame of the ROBOT (see Figure 8‑8). To be considered supported, a minimum of ½ in. (~13 mm) at each end of each BUMPER wood segment must be backed by the FRAME PERIMETER (≤¼ in. gap, ~6mm). “Ends” exclude hard BUMPER parts which extend past the FRAME PERIMETER permitted by R408-B. Additionally, any gap between the backing material and the frame:

R401      *BUMPERS all around. ROBOTS are required to use BUMPERS to protect the entire FRAME PERIMETER. Gaps of less than ½ in. between adjacent segments are permitted as long as all corners are filled per R409.

R409      *Fill BUMPER corners. Corner joints between BUMPERS must be filled with pool noodle material. Examples of implementation are shown in Figure 8‑7.
