At least when bumping to pass per G38.
Per EricH: I believe that ALL parts of the robot within the bumper zone must be within 10 degrees of vertical. (And the rule is 2/3 of the perimeter is required to be bumpered.)
Correct, I just assumed that the bumpers would be vertical.
Per EricH: It wouldn't be a bad idea to have the bumpers excluded, but that makes the refs' job a bit harder. Bumpers can give a nice easy reference.
Maybe it would make the job easier since the bumpers typically are not attached at weigh-in/sizing. The inspectors could make this determination before the robot ever hits the track. I could easily see two vertical poles 80 inches apart with the robot on a flat cart. The team would to have physically move anything that goes beyond the starting envelope through its full range of motion. If at anytime the robot and manipulator or whatever can not pass between the post the robot it is not constructed "in accordance with all of the 2008 FRC rules" (quote from Inspection Checklist) and would not pass inspection. You would not have to attach your bumpers which are usually off the robot at this time to prove compliance with R16. It almost makes R16 obsolete. However, if you were using more than 80 inches of your infinite height in the playing configuration and tipped over before retracting you could still get the penalty on the field. That is the only time the refs would have to worry about R16. The top of the overpass will be approximately 80", within an inch or two anyway, and could easily be used as a visual reference when a robot is tipping (i.e. was it taller than the overpass when it fell or not) and my guess is that near the overpass is where most teams will be going higher than 80 inches to begin with. I could see that this would become a pain if you have to power up your robot to have it move through the range of motions during weigh-in. However, for those teams that are using programing vs hard stops to limit motion it would be an ideal time to prove out their software.
Per GaryV: It's there - I had to look to be sure. I'm not sure if the requirement to bump with or against a bumper was added in the revised G38 or not.
They only added: during teleoperated period, in revision #2
