Climbing robot

The invention discloses a climbing robot. The climbing robot comprises two climbing units arranged at upper and lower parts, and multiple elevating mechanisms arranged between the two climbing units. The elevating mechanisms drive the two climbing units to alternatively move along an object to be climbed, so that the climbing robot can climb. Each clamping mechanism is provided with a touch sensor, the touch sensor is triggered after the clamping end of the clamping mechanism is jacked to the object to be climbed, then the clamping end of the clamping mechanism stops moving until the clamping ends of all the clamping mechanisms are jacked to the object to be climbed, then the clamping ends of all the clamping mechanism simultaneously move to the object to be climbed. The climbing robot can achieve relatively high weight bearing capability through the design of the annular climbing units, can carry workers and equipment to climb trees, and facilitates the research on growing states of the trees by scientific researches. By employing the touch sensors, a phenomenon that forces applied by the clamping mechanisms are nonuniform, therefore a frame deforms, the normal work of the robot is influenced, and the service lifetime of the robot is shortened is avoided.
