R405       *BUMPERS interact with BUMPERS. While navigating the FIELD normally, all BUMPERS must have padding (per R402-A) supported by backing (per R402-B) entirely filling the BUMPER ZONE, a space between 2.5in (6.35cm) and 5.75in (14.61cm) from the floor.

Figure 8‑9 BUMPER ZONE examples

This measurement is intended to be made in a ROBOT’S expected configuration(s) while navigating the FIELD and is relative to whatever surface the ROBOT is currently driving on. BUMPERS leaving the BUMPER ZONE due to ROBOTS inadvertently tipping is not a violation of this rule.
