The development process of micro pipe inspection robot and the detection methods within bore are studied. Mechanical structure and working principle of self-designed photoing robot in bore is analyzed and the introduction of single worm shaft with three worm gears transmission mechanism and adjustable screw nut adjustment mechanism are highlighted. And a Multi-body dynamics model based on ADAMS/View software is built on. Kinematics accuracy analysis and dynamics simulation analysis provide some data basis for improving the design parameters of the preliminary model. The control circuitry based on ATmega128 microcontroller chip for the photoing robot in bore is designed. The electrical and mechanical systems co-simulation under MATLAB/Simulink and ADAMS/View software verify the reliability and stability of its function and provide a certain reference value for future studies of similar products.
