Re: Quick release bumper design

Dick,
The 1" hard parts rule refers to any hard parts that extend beyond the frame perimeter not that intrude on the frame perimeter. This rule simply insures that a team does not construct their bumpers with fasteners that project beyond the pool noodles when hit. At all times, robot to robot and robot to field interaction must be shielded by pool noodles including the corners. See Fig 4-1.
As for the hardware/structure used to mount bumpers, the intent is that major robot structure is not moved to the bumper assy in order to bypass the robot weight limit and thereby increase the weight of the robot. Brackets, angles drilled and/or threaded, clevis and other attachments to hold bumpers in place will be weighed with the bumpers. Other structures that are meant to be robot structure will be weighed with the robot. This part of the bumper rules has not changed significantly in the past three years.
