In terms of a Robot Inspector, the "Safety Inspection" allows you to participate in practice matches. The RI will give a brief check for any major safety issues, such as no bumpers, grossly miswired power, chainsaws and axes, that sort of stuff. That is typically done at weigh-in, and takes a few tens of seconds only. Your safety inspection is completed when you get your inspection sticker, and your full inspection is when you get your colored dot and the inspectors initials on the sticker.
