Design of a glass climbing robot

Wall-climbing robot is very useful in substituting human labors in dangerous and
repetitive tasks like cleaning glass window in high building, maintenance, and inspection
in industrial storage tank. A success in developing a climbing robot presents a huge
economic benefit. This project aims to design a remote-controlled climbing robot that is
able to operate on a vertical glass window. An effective adhesion mechanism using
suction cups and solenoid valves had been designed. The locomotion mechanisms design
based on a crossed-bar mechanism, utilizing pinion and rack. Detail drawings of the
design and the robot specification had been finalized. A prototype was fabricated to
demonstrate the design concept and its functionality. Control system of the robot, which
includes an electrical circuit integrated with a C program, had been developed. Finally
the functionality of the fabricated prototype was tested.
