Ok, so this causes some problems for us... The way we are set up right now, i guess we break this rule as bolt heads extrude. If the bumper wood is already 3/4" thick, i dont see why first wouldnt allow for .25" extrusions max for bolt heads... Anyway, as it is now, our bumpers have an large, sturdy L bracket that is attached to the bumper perminantly and taps into our frame to attach there. I know that the bumper must rest fully along the frame also. So could we just attach the L bracket instead permentally to the robot (extending out of the frame 1/4 inches, making it a permiant fixture) and then just mount the bumpers onto that? It isnt as structural and is a bit harder to remove and adds weight to our robot, but would this be an acceptable solution?
