R103       *Robot weight limit. The Robot weight must not exceed 125 lbs. (~56 kg). When determining weight, the basic Robot structure and all elements of all additional Mechanisms that might be used in a single configuration of the Robot shall be weighed together (see I103).

I105         *Don’t exploit re-inspection. Teams may not use the re-inspection process in I104 to circumvent the weight limit in I103.

I104         *Unless the change is listed below, any change to a Robot must get re-inspected. A Robot may play Matches with a subset of the Mechanisms that were present during inspection provided the reconfigured Robot still complies with all Robot Construction Rules. Only Mechanisms that were present during the inspection may be added, removed, or reconfigured between Matches without re-inspection per this rule. If a Robot is modified after its most recent passed inspection, it must be re-inspected before it is eligible to participate in a Match. A Robot that plays in a Match with an un-inspected modification may be retro-actively disqualified at the discretion of the LRI and Head Referee.

I106         *Robots are off for inspection (mostly). For the safety of all those involved, Robots, must be presented for inspection with the Robot powered off, pneumatics unpressurized, and springs or other stored energy devices in their lowest potential energy states (e.g. battery removed).
