Inspection Robot Using Digital Image Processing

This research work presents a inspection robot for crack detection on the structures. It uses suction cups and servo motors to generate motion and adhesion. This robot is capable of climbing vertical and rough planes by attaching suction cups to the surface and removing it from the surface. Therefore it requires constant amount of energy to climb the planes and Vacuum pumps gives additional energy to the suction cups to maintain adhesion. The detailed design of the robot is modelled and fabrication is performed. The goal of the robot is to detect cracks on the wall of the structures. For that purpose the robot uses digital image processing to aid visual inspection. Canny edge detection method is used to detect edges. Images are stored in the database and are later inspected visually by the operator.
