Q. Regarding bumper rules (R28-R35), we would like to make the fabric instead of the bumpers interchangable while maintaining compliance with all of these rules. We see no rules requiring separate red and blue bumpers. Have we missed a rule that would prevent this design?
A. There are no Rules regarding how a team chooses to meet the blue and red bumper requirement of Rule [R34].

Q. Can one of the bumper covers be made with elastic so that the team can slip the alliance color over the bumper, for quick alliance color change?
A. There are no rules that prohibit this method for accommodating Rule [R32].

Q. To preserve material and time, it is possible to cover the bumper with a white clothe and make red and blue rectangle (reversible) whit our number. In this way, only the corners of the robot gone be white. Perhaps, if it not possible, can we make blue and red corners to dissimulate de white corner.
A. There are no Rules prohibiting a changeable color cover; however, the entire Bumper (including corners) must be either red or blue during the Match as per [R28-D].
