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.

*BUMPERS must be soft. Hard
parts of BUMPERS must not extend more than 1.25in (3.17cm) out from the ROBOT
PERIMETER. Only padding (per R402-A), cover
(per R402-C,
including any coatings or markings), and soft fasteners used to secure padding
or cover are permitted beyond this limit. Padding must extend at least 2.0in (5.08cm)
beyond any hard parts of the BUMPER. There is no limit on how far BUMPER hard
parts may extend inside the ROBOT FRAME PERIMETER.

*BUMPER extension limit.
BUMPERS must not extend more than 4.0in (10.16cm) from the ROBOT PERIMETER.
Rule R401
R401
*BUMPERS almost all around. ROBOTS
are required to use BUMPERS to protect the entire ROBOT PERIMETER. Gaps of less than 1.25in (3.17cm) between adjacent
segments are permitted as long as all corners are filled per R406.
A single gap larger than 1.25in (3.17cm) is permitted, as long as at least 5.0in
(12.7cm) of ROBOT PERIMETER on each side of each corner is protected by BUMPER.
Rule R406
R406
*Fill BUMPER corners. Corner joints between
BUMPERS must be filled with uncompressed padding material extending at least 2.25in
(5.72cm) from the corner with no gaps or voids. Examples of implementation
are shown in Figure 8‑10.
