Robot

The present invention relates to a robot which runs along a multi-splitting overhead high voltage transmission line, in particular to the structure improvement of a robot which runs along the whole course of an overhead high voltage transmission line. The present invention creatively connects the lower end of a big arm with a gravity adjusting mechanism by a support frame. The gravity adjusting mechanism has the function of adjusting the gravity of the robot at proper time during the process that the robot moves forwards by two arms in turn, so as to ensure that the robot is stable during therunning process, can not cause the gravity excursion of a whole operation vehicle and cause the phenomenon that the operation vehicle can not run stably on a transmission line. In addition, the robotcan run along the whole line of the overhead high voltage transmission line and can span over or avoid various kinds of barriers on the line, and the robot is not required to be conveyed from one sideof a pole tower to the oth
