[Max Lobovsky]

Before the official competition matches start, your robot must be inspected by volunteer inspectors. They have a check list to check for compliance with electrical, pneumatic, etc rules. They request an inventory of all the parts used on the robot and their cost. Finally, your robot is taken to a scale and a large measuring box to check if it fits size and weight requirements.

At some regionals (I have not seen this myself), inspectors perform random spot checks throughout the competition because it would be possible to modify your robot illegaly after the first inspection.
