I'll say this: It's illegal. That's that.

Plus, it's impossible. During hybrid mode, the robot doesn't accept inputs from controllers. It runs solely off of the code put on it. By making this contraption, you are essentially creating a new controller, and though it will send inputs, the robot will not receive them until telep mode. And then, it's a lot more accurate to use a controller.

Also, what you're describing is essentially the kinect. Why do a whole other thing?

EDIT: See exact ruling below.
