The official VEX IQ Robotics Competition Question & Answer system has closed for this season.
Official Q&A: VEX IQ Robotics Competition 2024-2025: Rapid Relay
2056: Unattached parts
G6 states that we cannot detach parts or leave parts on the field, but it does not mention if we could start the match with detached parts that stay contained within the robot itself.
example using detached round pieces to help a contraption roll around the robot sort of like ball bearings
Provided the detached part remains contained within the Robot and does not separate from the rest of the Robot, this could be allowed. As described in rule <R3> clause F, the final determination of whether a specific mechanism can be used on a Robot will be made by the Head Referee at the event.
If any part or mechanism, including this one, detaches from the Robot and is left behind on the Field, it is a violation of rule <G6>.
