Development of a Hardware-in-the-Loop Simulator for Analyzing Motion of Multi-DoF Robots Without Modeling Complex Joint Parts

In general, a multi-degree of freedom (DoF) robot comprises multi joints which are difficult to model precisely in numerical simulation. This paper proposes a Hardware-in-the-Loop Simulator (HILS) to analyze the motion of the multi-DoF robot without modeling complex joint parts by using multiple joint test devices. In this paper, we verify the proposed method by comparing the joint trajectory between a planar 2 DoF manipulator and the HILS.
