True, Just make sure you don’t step on it
It is allowable to have your controller in your hand during autonomous, but it is really up to the discretion of the referees. Here in Wisconsin, it is generally accepted procedure to have all teams place their controllers on the floor during autonomous. We feel that keeps away any possible appearance of drivers interfering during the autonomous period. As for your dq questions, the best place to find the answers are to read the Game Manual as others have pointed out.
