Answered: Clarification on SG5

Is it legal for an ultrasonic sensor mounted to a robot to receive input from outside the field. For example: the robot is parked near one of the 20" goals and the coach waves his/her hand (assuming the hand does not break the plane of the field) and the robot then performs any number of actions i.e. out-taking, backing up etc…

Edit:

My question arises out of the fact that “contact” is not defined in the VEX Gateway Manual and throughout the manual contact seems to imply physical touching.

This is not legal.
