Robot inspecting is the main development direction of the electric inspection

but compared with helicopters

UAVs

and substation inspection robot

inspection robot for transmission lines in China has not yet reached a practical level. We studied the key technology of robot practical inspection for transmission line

and put forward several typical operation modes of robot inspecting. Moreover

we developed two kinds of inspection robot of robot to pass obstacles and robot to cross obstacles

and proposed a transformation method of robot walking path.For the first time

we designed the device of robot autonomous on-line and off-line

and implemented the development of independent inspection system of robot. The robot has got through a variety of complex nature

electromagnetic environment condition test and outdoor function test based on really line section

and has carried out the demonstrational application on 500 k V live operation line. The robot can carry out simultaneously visible light and infrared detection. In the inspection

the problems of inspection system are exposed and solved

the emergency rescue measures under the abnormal situation of the robot are put forward and carried out successfully. The robot has a single time inspection mileage of 10 km or more

and the inspection application has achieved good results

the robot inspection system has reached a certain practical level.
