The Development of Climbing Mechanism for Cable Inspection Robot

For the maintenance of large cable-stayed bridge,cable inspection task using robot becomes an alternative methodthat is safer, easier and more efficient than a manual inspection.The method is believed to be superior than using drone or humanin performing the cable inspection. Our research work focuses onthe development of climbing mechanism for cable inspectionrobot. Our design of climbing mechanism enables the robot toclimb on 115 mm cylindrical object, e.g. supporting cable or beamof the bridge. The mechanism can be controlled wirelessly to climbthe cylindrical object with the diameter between 100 mm to 120mm at maximum speed of 10 mm/s. The mechanism is powered byLi-Ion battery that is capable to reach 50 meter distance withoutthe need of charging. The mechanism is also equipped with camerato take pictures of physical inspected objects, e.g. outer part ofcable
