Analysis of Key Technologies of Underground Inspection Robot and Design of Its Manipulator

According to the special underground environment and the research and application status of inspection robot, the key technologies of underground inspection robot such as mobile platform, autonomous navigation and positioning, intelligent control, autonomous charging, background management and online fault diagnosis are discussed. This paper focuses on the design of a special mechanical arm for inspection robot. Combined with the requirements of underground belt conveyor in coal mine, the working space, torque and tension of the mechanical arm, the pressure of gripper and its mechanism realization are calculated, which can add innovative key technology to mine intelligence, and has engineering application value and economic significance.
