An Alternating Stepping Climbing Machine Based on TRIZ Theory Optimization

The unmanned handling vehicle (AGV) has a wide range of applications in both civil and industrial fields, and can replace manual labor to complete the handling work. In the thesis, we use TRIZ theory to optimize the existing stepping climbing mechanism, design a high efficiency and high stability of the climbing machine, the front of the climbing machine for the double-centered crank rocker mechanism, the use of alternate stepping to complete the climbing movement, improve the efficiency of climbing, the back of a crank slider mechanism to achieve the function of auxiliary pressure to climb the stairs, and with the electric actuator to regulate the position of the center of gravity, to ensure the stability of climbing the stairs. The center of gravity is adjusted with an electric actuator to ensure the stability of climbing. We have carried out theoretical calculations, simulation verification and physical verification to confirm the feasibility of the stair climber.
