ABSTRACT
The authors have developed a cable inspection robot for the cable-stayed bridges (CSBs). The robot is possible to photograph the entire circumference of the CSB cable surface with several cameras while moving up and down along the cable, and then creating an image development diagram of the CSB cable surface from the video. By utilizing an image development diagram, it is possible to confirm the position and the shape of damage to the cable, which can be difficult to grasp using video only.
