Abstract
Bridge inspection robots are expected to pass through obstacles such as bolted spliced part and right-angled routes. This paper was aimed at developing a bridge inspection robot which is capable of traveling on bolted spliced part. Two-wheel-drive robot was developed. It is equipped with two rimless wheels as propulsion wheels. Each of the spoke is tipped with a neodymium magnet. Trailing wheels are aggregate of magnetic wheel with a caster. The robot can do the pivot turn to avoid the splicing bolt. Experiments were conducted to check the performance of the robot. The robot attempted to travel on bolted splice part and eight right-angled routes. It is found that the robot could pass through the splice part. Moreover, it produced high success rates of the internal right-angle routes.
