Abstract
This paper presents the bridge cable inspection robot developed in Korea. Two types of the cable inspection robots were developed for cable-suspension bridges and cable-stayed bridge. The design of the robot system and performance of the NDT techniques associated with the cable inspection robot are discussed. A review on recent advances in emerging robot-based inspection technologies for bridge cables and current bridge cable inspection methods is also presented.
Highlights
Bridges are important national assets that should be properly maintained to ensure public safety
The robotics technologies are usually combined with powerful nondestructive testing (NDT) techniques for bridge cable systems that are hardly accessible with current inspection practices
This paper consists of two parts: (i) overview on current cable inspection methods (Sections 2 and 3) and (ii) introduction to the cable inspection robot developed in Korea (Section 4)
Summary
Bridges are important national assets that should be properly maintained to ensure public safety. Long-span cable-supported bridges require high maintenance associated with reliable and efficient inspection methods. The development of reliable inspection methods is imperative to assess material and structural conditions of cable systems [2]. Limitations of the current cable inspection methods can be overcome using emerging robotics technologies. The robotics technologies are usually combined with powerful nondestructive testing (NDT) techniques for bridge cable systems that are hardly accessible with current inspection practices. This paper reviews recent advances in robot-based inspection technologies for bridge cables. This paper consists of two parts: (i) overview on current cable inspection methods (Sections 2 and 3) and (ii) introduction to the cable inspection robot developed in Korea (Section 4).
