[MECHANISMS are considered “active” if they are in motion relative to the ROBOT while in contact with the BALL. Resetting or moving MECHANISMS while not in contact with a BALL is permitted as the MECHANISMS are not considered “active.”]

What about a robot part that moves due to forces such as the impact of the ball, or inertia related to robot accelerations? For example, a loose cargo net, which would move if the robot stopped or turned suddenly and of course when hit by a ball. How about a padded surface that gets depressed by a ball hitting it? Both of these are 'moving' relative to the robot while in contact with the ball.

It seems the 'spirit' of the "active" definition seems to apply to mechanisms which move due to robot actuators.
