Abstract

This paper proposed a new mechanism design of the inspection robot by running through the high voltage transmission line to improve the negotiation efficiency and safety. By comprehensive consideration of the robot structural characteristics and running environment complexity

the inspection robot was designed based on the compound wheel-arm mechanism with two symmetrical arms at one side.This robot mechanism was comprised of driving mechanism

arm mechanism

pressing mechanism

locking mechanism and extending mechanism

all of which were illustrated in details. The kinematic model was developed based on the D-H method to validate the proposed mechanism design. The results showed that it satisfied the requirement of motion. The experiments were carried out both on the simulated and real world high voltage lines. The implementations indicated that

low degree of freedom and compact structure simplified the negotiation of inspection robot

and improved the negotiation safety and efficiency when the robot ran on the high voltage line. Moreover

this mechanism design helped to improve the robot running ability with long distance automatically

and made the robot be more applicable to complex running line environments.
