There is a rule, <R07-D> that states: "BUMPERS segments must have a minimum length of six inches (as defined by the BUMPER backing), and a maximum length that does not exceed the maximum horizontal dimension of the robot (except for the soft cushion in the corner, as permitted by Rule <Ro7-C>)"

to me, that means that you can't have one bumper, because one bumper around the entire robot means that it would exceed the maximum horizontal dimension of the robot...
