Hexapod Biomimetic Robot Design and Analysis: A Tiger Beetle Inspired Approach

The hexapod biomimetic robot is a robot that simulates the six-legged gait of insects, with high adaptability and flexibility, capable of walking, climbing, and overcoming obstacles in complex environments. The paper investigates the development history of hexapod biomimetic robots at home and abroad and finds that biomimetic robots have a wide range of application areas and values in modern production and life. The research focuses on the tiger beetle as the research object. By analyzing the body structure and movement of the tiger beetle, a biomimetic foundation is provided for modeling the hexapod biomimetic robot. Through further simplification and analysis, the various parts are completed in 3D modeling and assembly using SOLIDWORKS software. By analyzing the limit state of the hexapod biomimetic robot under the triangular gait, the maximum torque required for the hip joint and tibia joint is calculated under the condition of three-legged support, and the stress and deformation at the hip joint and tibia joint are analyzed using ANSYS software, which meets the requirements. The assembly model is imported into ADAMS, and the drive, contact force, and relevant parameters are set in ADAMS. The corresponding motion function is set on the drive to drive the hexapod biomimetic robot to walk in a straight line, while measuring the center of mass and joints of the hexapod biomimetic robot to verify whether it can meet the requirements of walking in a straight line. The results meet the requirements. This paper designs the structure of the hexapod biomimetic robot and uses ANSYS finite element analysis and ADAMS motion analysis to provide a theoretical basis for the subsequent design of the hexapod biomimetic robot.
