“…As shown in Figure 1(a), the links ABC, CD, DE, and EB form a four-bar mechanism, which has advantages of good rigidity, high bearing capacity, and ease of control. [31][32][33] The solid and dotted lines correspond to the robot in the wheel and leg states, respectively. Link AFG refers to change in the movement of the bionic-series leg structure.…”

Rescue robots can replace rescue workers in search and rescue missions in unknown environments and hence play an important role in disaster relief. To realize the advantages of high carrying capacity, easy control, and simple structure to adapt to a complex disaster scene, a novel wheel-legged rescue robot, integrated with rescue function modules, was designed for the present work. Three motion states were analyzed in detail. Mechanical properties were studied to provide basis for parameter optimization. The performance indices, which include mechanical properties, motion amplitudes and movement stability, were proposed, and the structural parameters were further analyzed and optimized based on these performance indices to make the overall performance of the robot achieve the best. Results show that the motion state of the wheel-legged rescue robot can perform real-time transformations and hence can be used in complex environments.

“…The legs of the creature include the hip, knee, and ankle joints, which are typical series mechanism. The leg structures of many bioinspired jumping robots mimic the biological leg structure and have good jump performance [ 34 ]. In 1991, Zeglin et al designed a one-legged jumping robot Uniroo, which mimics kangaroo locomotion in order to gain insight into the nature of jumping ( Figure 4 ).…”

“…The results show that the multiconstrained buffering leg has stronger energy storage capacity; the performance of the bionic buffering leg is poor, but the motion flexibility is higher; the arc buffering leg is simple in structure, and the buffering performance is between the bionic buffering leg and the multiconstrained buffering leg. It provides a reference for the selection of the buffering legs or the structural design of the new type of buffering legs [ 34 ].…”

A bioinspired jumping robot has a strong ability to overcome obstacles. It can be applied to the occasion with complex and changeable environment, such as detection of planet surface, postdisaster relief, and military reconnaissance. So the bioinspired jumping robot has broad application prospect. The jumping process of the robot can be divided into three stages: takeoff, air posture adjustment, and landing buffer. The motivation of this review is to investigate the research results of the most published bioinspired jumping robots for these three stages. Then, the movement performance of the bioinspired jumping robots is analyzed and compared quantitatively. Then, the limitation of the research on bioinspired jumping robots is discussed, such as the research on the mechanism of biological motion is not thorough enough, the research method about structural design, material applications, and control are still traditional, and energy utilization is low, which make the robots far from practical applications. Finally, the development trend is summarized. This review provides a reference for further research of bioinspired jumping robots.

“…According to the different structure form, wheel-legged structure of the robot can be divided into series structure, similar parallel structure, and simplified structure. The leg of mammals and insects has three parts: thigh (femur), calf (tibia), and foot (tarsus); thus, the leg can be considered as a series mechanism [14]. Many wheellegged structures were designed by mimicking biological leg structure and have the advantages of high flexibility.…”

A wheel-legged rescue robot design with strong environmental adaptability is proposed. The design presented is aimed at helping rescue workers complete their missions, such as environmental and personnel search, quickly and accurately. So it has broad application prospects. In order to achieve the advantages of simple structure, easy control, small occupation space, and wide motion range, a wheel-legged rescue robot is designed in this paper, and the robot can realize three kinds of motion states, which include wheel state, rotation center lifting process, and leg state. Then the motion states are analyzed in detail, which provides a reference for motion control. Considering the wheel state and leg state share the same structure to contact with the ground, the effect of the stiffness of wheel-legged structure to the motion performance is analyzed. Then the experiment is carried out to prove the feasibility of the structure design. This study offers a design and quantitative analysis for wheel-legged rescue robot. Furthermore, a basis for future control research and engineering applications is established.
