Bianca,
I know it might be hard to filter out the answer from above posts. You must conform to the bumper rules in that only one actual bumper system can fit on your robot between the 2" and 10" above the floor. (the dimensions allow only 8" while a bumper that is correctly constructed will be at least 5" high) It is possible and legal however, for parts of your bumper system to mounted low and others to be mounted high as long as all of the rules for bumpers are followed. Specifically, the minimum 8" segment on either side of an exterior vertex and all bumper construction rules.
