The invention discloses a robot used for detecting high voltage transmission lines, comprising a walking mechanism, a ground control system and an airborne control system. When in use, the walking mechanism is hung on a lead by a V-shaped wheel. A ground processor sends out forward and reverse commands and other commands. The commands are sent by a ground wireless data transceiver and transmittedby an airborne wireless data transceiver to an airborne processor. The airborne processor sends out a command to control the robot to carry out corresponding actions. A plurality of sensors arranged on the walking mechanism can acquire the walking state information of the robot and transmit the information to the airborne processor, and the information is transmitted by the airborne wireless datatransceiver and the ground wireless data transceiver to the ground processor to be displayed and output. The robot of the invention can realize remotely acquiring own state information and facilitateremote control, can replace artificial line patrol, overcome the defects of low accuracy, strong labor intensity and blind areas, simultaneously replace the helicopters to carry the apparatuses to carry out line patrol, improve the safety of line patrol and lower the cost of line patrol.
