Type Synthesis for One-dimensional Remote-center-of-motion Mechanisms

Abstract

Abstract: The type synthesis for one-dimensional remote center of motion (RCM) mechanisms is the base of the study of multi-DOF RCM mechanism. Due to types of present RCM mechanisms are few, it is necessary to find an efficient way to create more new RCM mechanisms. Existing 1-DOF RCM mechanisms are classified. Five types of RCM mechanisms are given, such as single-revolute-joint, circular-prismatic-joint, parallelogram-based, synchronous-transmission-based and instantaneous RCM mechanisms. Based on a proposed concept of the planar virtual center (VC) mechanism, which is a more generalized concept than an RCM mechanism, an approach of type synthesis for 1-DOF RCM mechanisms is addressed by assembling two planar VC mechanisms. This approach can synthesize parallel or mixed RCM mechanisms. Concrete examples are given, and some new configurations are obtained, and which proves the effectiveness of the type synthesis method.

Key words: Remote center of motion mechanisms, Type synthesis, Virtual center mechanisms
