DEVICE CAPABLE OF ADHERING BY SUCTION TO OBJECT SURFACE AND TRAVELING THEREALONG

摘要

A device is at least formed from a suction unit, Y-axis reciprocating units, Z-axis reciprocating units, double-acting leg members, second Z-axis reciprocating units, and second double-acting leg members. As a first step for enabling the device to travel along an object surface, the double-acting leg members are strongly pressed against the object surface. As a second step, the suction unit is moved in the traveling direction of the device with the double-acting leg members strongly pressed against the object surface. As a third step, the double-acting leg members are separated from the object surface. As a fourth step, with the double-acting leg members separated from the object surface, the double-acting leg members are moved in the traveling direction of the device and returned to the state immediately prior to the first step. Thereafter, the actions of the first to fourth steps are repeated.
