Kinematic Analysis of a Centrally Driven Humanoid Robotic Arm

Abstract

Abstract The humanoid robotic arm has a broad prospect in the field of human-machine cooperation, but the large inertia of the current joint robotic arm slows down its response speed and running speed. In this study, a centrally driven humanoid robotic arm is introduced, which has the characteristics of small inertia, good rapidity, and high load. Screw Theory is used to establish the kinematic model and analyze that the robotic arm has no singular configuration in the working range. The geometric method and Monte Carlo method are used to analyze and verify its workspace, which is the basis for the subsequent dynamic analysis and control of the robotic arm.
