Multi-cam control type three-arm high voltage line walking obstacle avoidance robot

The utility model relates to a multi-cam control type three-arm high voltage line walking obstacle avoidance robot comprising a first robot arm fixed on the left side of a mount through a left support arm and a right support arm, and the first robot arm is positioned right behind a crossbeam; a second robot arm is fixed in middle of the mount through the left and right support arms, and arranged right in front of the crossbeam of the mount; a third robot arm is fixed on the right side of the mount through the left and right support arms, and arranged right behind the crossbeam of the mount; bottoms of the three robot arms are respectively provided with a disc cam and a vertical cone gear; the front end of a rotary shaft is provided with a swing motor, and the rotary shaft is fixed on the bottom of the mount; the disc cam and the vertical cone gear are concentrically fixed on the rotary shaft. The advantages are that the cam motions can control robot arm motions, so the robot can avoid the obstacle and can return to an original position for being clamped; the high voltage line walking robot is cam-driving type, less in motor number, and high in climbing performance.
