the drawing shows a ROBOT BUMPER PERIMETER with BUMPERS (blue) and corner fillers (red) which I think reasonably represents the ROBOT and CORNER in question.
The BUMPER PERIMETER is a polygon. The polygon has 6 corners; A,B,C,D,E,F. 2 of the corners, D,E, have right angles. 4 of the corners, A,B,C,F, have obtuse oblique angles. The polygon has 6 sides; AB,BC,CD,DE,EF,FA.
The corner in question with respect to this thread is corner A. There are 2 sides "of corner A", side AB and side FA.
Each side of the corner, side AB and side FA, is protected by BUMPERS. Each sides protection clearly meets the intent of <R08> ..."If implemented as intended, a ROBOT that is driven into a vertical wall in any normal PLAYING CONFIGURATION will always have the BUMPER be the first thing to contact the wall."... . Side AB has no BUMPERS on it yet the BUMPER configuration clearly meets the intent of the rule, which is clearly stated.
EricH, I enjoy reading your may posts in these fora. I think you do a lot to contribute positively with your comments. However I must take issue with your position on this question. What I believe are the relative sentences from your referenced sources follow, with my comments appended:
Reference #1: "Both sides of the corner must be protected." Comment: they are, see above.
Reference #2: "Both sides of the corner must be protected by BUMPER segments." Comment: they are, see above. "Rule <R08-i> requires BUMPER protection on every corner of the BUMPER PERIMETER." There is obviously BUMPER protection on every corner of the BUMPER PERIMETER, see above drawing.
Reference #3: This reference is not on point because the answer is given with respect to a rectangular ROBOT BUMPER PERIMETER, not the BUMPER PERIMETER in question.
Reference #4: "The interpretation that "both sides of an exterior corner must be protected with segments of bumpers, and the bumper segments must be a minimum of 6 inches" is correct." Comment: both sides of the corner are protected, see above, and the bumper segments in the example can be easily made to meet the 6" minimum dimension requirement.
Mike8519: You state ..."those corners must be protected by 6" of bumper on each side"..... I think if you read carefully the requirements typically state ..."both sides of the corner must be protected"... not, corners must be protected on each side. They do not mean the same thing.
Thanks to all for contributing to the discussion,
Scott
