A device capable of suction-adhering to and moving along the surface of an object includes a pressure reduction housing, a suction-adhering seal mounted on the pressure reduction housing and defining a pressure reduction space in cooperation with the pressure reduction housing and the surface of the object, and a vacuum generator for discharging a fluid from the pressure reduction space to the outside of the pressure reduction space. The device suction-adheres to the surface of the object by the pressure of an ambient fluid acting on the pressure reduction housing owing to the difference in fluid pressure between the inside and the outside of the pressure reduction space. The device is moved along the surface of the object by driven wheels which engage the surface. At least that portion of the suction-adhering seal which contacts the surface of the object vibrates in a manner which creates a dynamic friction force to decrease the frictional force between the suction-adhering seal and the surface of the object.

Abstract

A device capable of suction-adhering to and moving along the surface of an object includes a pressure reduction housing, a suction-adhering seal mounted on the pressure reduction housing and defining a pressure reduction space in cooperation with the pressure reduction housing and the surface of the object, and a vacuum generator for discharging a fluid from the pressure reduction space to the outside of the pressure reduction space. The device suction-adheres to the surface of the object by the pressure of an ambient fluid acting on the pressure reduction housing owing to the difference in fluid pressure between the inside and the outside of the pressure reduction space. The device is moved along the surface of the object by driven wheels which engage the surface. At least that portion of the suction-adhering seal which contacts the surface of the object vibrates in a manner which creates a dynamic friction force to decrease the frictional force between the suction-adhering seal and the surface of the object.
