1) The shelves are wire mesh. The next rules update will include a revision to include a back board made of a 1x6 that will connect one divider wall to the next and also give it more structural rigidity. The 1x6 will be screwed in on an angle from the corner of the divider at the top rear towards the end of the wire shelving unit. Thus creating an angle and a gap at the bottom (not large enough for the juice bottle to fall through). Thus making it a tad more difficult to remove the juice bottles by simply pushing them off the back. They now may have to be picked up to be moved or removed, once on the lower scoring area.
2) the human interaction is only limited to not touching the robot in any way with any part of your body. Touching the juice bottle is not considered touching the robot, but don't slip up and grab any part of the robot for any reason.
3) the fence or border goes all the way around the perimeter of the field. The human area is a taped area on the carpet outside of the field, the interaction zone is out side of the border between the human area and the field.
