“…Hao Pang et al designed a bionic tire based on the African ostrich as a prototype. The traction and torque of the bionic wheel and the wheel with a rectangular pattern at different slip rates are compared via DEM, and the results showed that the bionic wheel has better traction and anti-sinking properties in sand [11]. Zhang Rui designed a bionic walking wheel with different attitudes toward the wheel-leg structure using an ostrich as the bionic object.…”

To improve wheel trafficability in soft and muddy soils such as paddy fields, a bionic walking wheel is designed based on the structural morphology and movement mode of the feet of waders living in marshes and mudflats, similar to the muddy soil of paddy fields. The bionic walking wheel adopts the arrangement of double-row wheel legs and staggered arrays to imitate the walking posture of waders. The two legs move alternately, cooperate with each other, and improve the smoothness of movement. The cam inside the bionic walking wheel is used to control the movement mode of the feet. The flippers open before touching the ground to increase the contact area and reduce sinking, and the toes bend and grip the ground while touching the ground to increase traction. Multi-rigid-body dynamics software (Adams View 2020) is used to simulate the movement of the wheel during the wading process, and the movement coordination and interference between the wheel legs are analyzed. The simulation results show that there is no interference between the parts and that the movement smoothness is good. The interaction between the bionic walking wheel and muddy soil was analyzed via coupled EDEM–ADAMS simulation, and the simulation analysis and experiments were conducted and compared with those for a common paddy wheel. The results showed that the bionic walking wheel designed in this paper improved the drawbar pull by 113.56% compared with that of a common paddy wheel and had better anti-sinking performance. By analyzing the effect of toe grip on traction, it was found that the soil under the feet can be disturbed to provide greater traction when the toe is bent downward. This study provides a reference for improving the trafficability of walking mechanisms in soft and muddy soils, such as paddy fields.

“…A Simulation of wheel soil interaction was also done to evaluate the compression, rolling resistance, bulldozing and wheel tractive force [24]. Pang et al (2021) was done comparative study between bionic and rectangular wheel designs, the bionic wheel was found to be more efficient when it came to the interaction between irregular structure wheels and lunar soil [25]. Rigid neoprene rubber has been selected due to its high coefficient of restitution [26].…”

The technical advancements in robotics have closely been followed by developments in aerospace excavation robots. This research elucidates self-designed shape memory alloy wheels for their use in Lunar Excavations, which attributes to the new era of space exploration robots. The wheel design proves to be of paramount importance as crucial operations such as mobility, steering, and traction control build upon wheel design. A comparison has been made between Aluminium alloy, Structural Steel, and Shape Memory alloy (Nitinol) wheels for both conventional and self-designed wheel architectures. Wheel architecture tests and their results are articulated with the aid of simulation. The significant performance parameters, primarily Total Deformation, Equivalent Stress, and Shear stress-induced, were analyzed, which articulates the performance of the wheel at the time of landing. It was observed that for both wheel designs: self-designed and conventional, the maximum total deformation was 0.011154 mm and 1.3573 mm, respectively, when Aluminium alloy was chosen as the base material. For Steel and Nitinol, the self-designed wheel structure proved to perform better than the conventional wheel design with lower values of total deformation (0.0041129 mm and 0.010968 mm, respectively).
