A new bionic structure of inspection robot for high voltage transmission line

Traditional inspection robot for high voltage transmission line robot is hard to cross the drainage line and other non straight line segment obstacle because of the small operation space. A new bionic structure of the inspection robot is proposed in this paper, which is combined the motion characteristics of primates with the modern design method and the principle of bionics. The mechanism model based on the three arms with symmetrical distributed and its crossing various obstacles on power line simulating to primates suspension pendulum movement are presented. The robot operation of crossing obstacle process is simulated and analyze with ADAMS software, thus the rationality and stability of the bionic mechanism are verified. Finally, the principle model and virtual prototype of robot are manufactured and testing on the practical power line.
