<R1> Only one (1) robot will be allowed to compete per team in the VEX Robotics Competition. Though it is expected that teams will make changes to their robot at the competition, a team is limited to only one (1) robot. The VEX *Robotics Design System is intended to be a mobile robotics design *platform. As such, a VEX robot, for the purposes of the VRC, has the following subsystems:
Subsystem 1: Mobile robotic base including wheels, tracks, legs, or any other mechanism that allows the robot to navigate the majority of the flat playing field surface.
Subsystem 2: Power and control system that includes a VEX legal battery, a VEX control system, and associated motors for the mobile robotic base.
Subsystem 3: Additional mechanisms (and associated motors) that allow manipulation of game objects or navigation of field obstacles.
Given the above definitions, a minimum robot for use in any VRC event (including skills challenges) must consist of 1 and 2 above. Thus if you are swapping out an entire subsystem of either item 1 or 2, you have now created a second robot and are no longer legal.
I feel that the interpretation of this must be that the robot has the ability to drive or move its base. The static base seems to me to clearly violate this. I know that there was a president at Worlds of a static base but I do not belief the ruling was correctly interpreted. A giant arm in my opinion is only a subsystem 2 & 3.

Last year our Hand of God concept was considered legal. It had no drive train. Its something to reconfirm again this year, because its a new game. But HOG was legal without a single motor for drive train, in fact. No drive train at all.
but intentions can still change year after year. I would assume a stationary robot is still legal this year based on the rule, BUT i would still ask it in the Q&A just so you have a printed copy for whoever inspects your robot at your competition to see. I know that the quality of events vastly differs based on who is running it and who has experience or not.
