In the tasks such as disaster rescue and military reconnaissance

the traditional robots often struggle to adapt to the dynamic environments due to their continuous and uncontrollable jumping characteristics. A frog-like jumping robot with independent control over energy storage and jumping actions is proposed. The robot′s legs are designed as a 3-RRR spatial parallel mechanism to imitate the frog′s hind leg push-off jumping motion. A single servo motor drives the latching and release mechanism to independently control the energy storage and transient jumping actions of the leg jumping mechanism. Through modeling and simulation

the driving force requirements and jumping performance of the robot are analyzed. The jumping experiments of the bionic robot prototype further verifies the effectiveness of the bionic design. The robot can achieve the controllable jumping

with a jumping distance reaching 20 times its body length.
