Abstract

Aiming to improve the performances and reduce the manufacturing cost of the current legs for quadruped robots, this paper presents a novel 3 DOF serial-parallel hybrid leg. We design a prototype 3D model and give the analytical expressions of inverse and forward kinematics. End-effector workspace is computed using the numerical forward kinematics. The analysis and calculations show that this hybrid leg with simple structure combines the advantages of both serial and parallel mechanisms: high stiffness, high bearing capacity, low structural inertia and large workspace. This research has great significance to a series of further studies on dynamic analysis, mechanism optimal and system control of this novel hybrid leg.
