Check out section R92 for details on what is and isn't allowed on the minibot.

If you want a controller, you must use the NXT. I believe that a simple custom circuit (switch, battery, motor) would also be legal.

There is no "proper" way to activate the minibot. This is all in your specific implementation.

As for shut down safeties- I would recommend it though because you will be penalized if you damage the field or any of the judges perceive you as a safety hazard.
