... as an adhesion mechanism for miniature wall climbing robots, and the miniature robot prototype with biomechanical suction cups can move in straight line and turn with a fixed angle on an inclined glass wall. Originality/value This paper describes how a miniature wall climbing robot with biomechanical suction...

... is designed for inspection of concrete walls. The propulsion system consists of three omnidirectional‐driven wheels for high maneuverability. The adhesion is performed by a vacuum system of seven controllable vacuum chambers and one large reservoir chamber. Pressure sensors and valves are integrated...

... Waals forces, unwanted adhesion through surface tension, contaminants etc. all serve to hinder the release process. The problem of object release can be solved by the addition of small piezoelectric actuators behind the electroadhesive surface (Monkman, 1999). Small vibrations can then be initiated...
