A methodology for geometric design of closed kinematic chain mechanisms

摘要

This paper presents a methodology for the geometric design of those closed-kinematic chain mechanisms consisting of two platforms connected by six linear actuators. The methodology provides a guideline for the placement of the linear actuator joints which can maximize the mechanism workspace and forces/torques. The paper explains how the presented methodology was applied in the design of two real-world robotic systems, a force reflecting hand controller of a teleoperation system and a fine motion mechanism of a munition loading system.
