Re: 1/2" gap in bumpers, is this acceptable?

Mike,
I am sorry to tell you this but the bumpers as pictured do not meet the rule. Specifically there are many parts to the rule but there are two parts that apply...

A. BUMPERS must provide complete protection of the entire FRAME PERIMETER of the ROBOT (i.e. BUMPERS must wrap entirely around the ROBOT). The BUMPERS must be located entirely within the BUMPER ZONE when the ROBOT is standing normally on a flat floor, and must remain there (i.e. the BUMPERS must not be articulated or designed to move outside of the BUMPER ZONE).

K. As part of the 100% coverage, BUMPERS must protect all exterior corners of the FRAME PERIMETER. For adequate protection, a full segment of BUMPER must be placed on each side of the corner (see Figure 8 - 2).

All is not lost as there is a fairly easy fix. All you need to do is add a 5" length of pool noodle, vertical orientation, at each end of the front and back bumpers covered in the fabric. This additional 2 1/2" of foam protects the corner and overlaps the adjoining bumper section. This addition must have no backing so you do not need to replace the 3/4" plywood backing. As I pointed out earlier, a little gap as shown in the first picture in this thread is expected and fits the rules that require complete frame coverage and satisfies that there are no hard parts in the corners.
