R22 states clearly the purpose of the bumper which is "to protect the frame perimeter" not the undercarriage or the inside of the robot, etc. With this rule in conjunction with R25, it would not seem to make sense not to allow the frame articulation as long as the bumpers continue to perform their one and only stated purpose. Also, if it were deployed as a defensive or offensive move perhaps it should not be allowed, but the end game is different (and autonomous too???)

It is likely not to be allowed given the Q&A precedence already in place but Would these thoughts have made a difference (perhaps they were mentioned in discussion but there is no way to know I guess).
