Bionic Jumping Robots: Design and Dynamics Verification Inspired by Biological Mechanisms

Bionic jumping robots represent a frontier in robotics, integrating biological principles to enhance mobility in complex environments. This study focuses on the design and dynamics verification of such robots, drawing inspiration from the efficient jumping mechanisms of kangaroos and locusts. The research introduces a bionic tendon-spring composite structure and a pneumatic-motor hybrid drive system to address limitations in traditional robotic jumping, such as low energy efficiency and poor terrain adaptability. Experimental results demonstrate that the robot achieves a maximum jump height of 2.3 meters at a 45 takeoff angle, with validated terrain adaptability across slopes and obstacles. However, material fatigue in bionic tendons remains a critical challenge, reducing tendon lifespan and robotic performance over repeated use. This work underscores the potential of biological mimicry in robotic design while highlighting the need for advancements in material science and control systems to overcome current engineering limitations.
