Upper left: Ideal path traversed by the inspection robot. Green x’s are the outbound part of the path. Red circles show the returning part of the path. With slight errors introduced into the actuation, paths such as those shown in the other panels are obtained. The primary effects are lack of precise loop closure, and non-straight approach and return paths. It can be seen that the path deviates from a perfect circle as well.
