Dynamic Analysis of Cable-Driven Humanoid Arm Based on Lagranges Equation
Human beings have flexible arms and legs that can ensure them conduct various challenging operations to work out daily requirements. Therefore, Humanoid mechanism design become hot research areas recently. To mimic the skeleton structure and driving scheme of a human arm, a 7-DOF cable-driven mechanism is determined to develop. Cable-driven mechanism allows actuators dont have to be placed on joints that makes it possesses several advantages such as low weight, high dexterity, and large reachable workspace compared with traditional configurations. The forward and inverse displacement analysis issues are conducted. In this paper, dynamic analysis of the cable-driven humanoid arm (CDHA) is conducted based on Lagranges method. The dynamic model is established by making use of twist-product-ofexponential formula and the cable tension distribution analysis is also addressed. At last, both the dynamic model and the algorithm are validated through several simulations in MATLAB.
