Design and development of a sealing-system for climbing-robots

The Institute of Machine Elements, Gears and Transmissions (MEGT) cooperates with a Robotics Research laboratory at the Department of computer science. This research group develops a climbing robot, which will be able to survey concrete walls in order to detect irregularities and errors in the structure of the wall. As the final result the robot should be able to drive without any external support, fixed at the wall by using a regulated system of seven vacuum chambers. The climbing-robot will not only be able to stick to the wall but will also be able to move on it while scanning the entire surface. These two requirements of fixing the body to the wall and simultaneously moving on it, demands a very tricky sealing-system, which will be developed at the institute of MEGT. In order to guarantee that the climbingrobot keeps contact to the wall, it is necessary to develop a special sealing which needs to be wear-resistant, leak-proof and easily sliding. By now several prototypes have been developed in order to test different sealing materials and shapes in order to find the optimum in friction and wear.
