Abstract

A wall-climbing robot for measuring capacity of vertical metal tanks includes a robot body including a chassis, a casing, and wheels. The robot body further includes: an attraction unit including a plurality of magnets; a measurement unit including a bendable ruler provided on the chassis and protruding from a top of the casing; the rust removal unit including a rust removing bucket provided at a front side of the robot body, and a driver for the lifting and lowering of the rust removing bucket; and a control unit including a microcontroller, a posture detector, an obstacle detector, an attraction detector, and a distance sensor. The wall-climbing robot of the present invention leaves no indentation on a surface of the metal tank, and is not affected by the rusts formed on the surface.
