Research status and development trends of walking wheels

As a new type of walking device for complex terrain that breaks through the limitations of common travel device, the walking wheel has significant application potential in the fields of resource development and agricultural production. It noted the development of the walking wheel from the original exploration to the institutional simulation to the motion simulation. In addition, it outlines relevant theoretical contents related to walking wheels, including traction efficiency, traction force, passability, the mechanical model of wheel-terrain interaction, and analysis of movement mechanisms. The analysis found that the current walking wheel also has problems such as sliding, high impact vibration, inadequate traction performance, poor smoothness and weak carrying capacity, leading to fewer applications in actual production. Based on this, the paper proposes a bionic engineering optimization path: by drawing on the excellent environmental adaptation mechanisms of organisms, and clarifies that future research should focus on three key directions: rigid-flexible coupled assembly, bionic structural design, and bionic material selection. This research provides a clear technical direction and theoretical support for the subsequent research and development of complex terrain walking devices. It provides a theoretical reference for the interaction between walking wheels and complex terrains in the field of terramechanics.
