I helped design and build a remote inspection robot for an Exelon Nuclear Power Plant. The robot had to drive into a radioactively hot area that was too dangerous for people to stay in for longer than a few minutes. The robot had to drive 40 feet up a vertical steel wall, fit under a 5 inch gap, and inspect a 20 foot length of a rubber gasket 4 feet away from the robot to search for a leak. We accomplished this by attaching multiple cameras to the robot, one on the end of a 3 foot rod that could rotate to get over an obstacle between the robot and the gasket. There was also tubing run to the robot to deliver smoke and helium to the end of the rod to better detect a leak.
