Robotic System for Searching Cracks beneath Bridge

�{ Abstract This paper proposes a robotic system for searching cracks beneath bridges. This robotic system for bridge inspection has been developed with aims of checking the safety status of a real bridge and gathering accurate data such as crack widths and lengths. The developed robot system is composed of the moving mechanism mounted on a specially designed car and the vision system for precise inspection. Especially, this paper emphasizes the system integration method to design and control the entire robot system. �{
