Focused on the characteristics of poor agricultural distribution network, large power supply range, high accident rate and difficult maintenance, the distribution network live working robot with master-slave tele-operation is studied. The overall design was included and completed, as well as the research of mobile insulation lifting mechanism, of robot high-altitude operation platform, and of man-machine operation interactive control system. The experimental results show that the master-slave tele-operation live working robot can accomplish live operation tasks such as disconnecting drainage line, removing branches and removing foreign bodies, and etc.
