Abstract

A new variable-DOF (degree-of-freedom) single-loop mechanism with seven revolute joints is proposed. The mechanism is constructed as a combination of two Bennett mechanisms and has two distinct 1-DOF 7R modes, where it is able to perform general 1-DOF 7R motion, and one 2-DOF double-Bennett mode, which is composed of two 1-DOF Bennett 4R motions. This paper shows the construction of this mechanism and analyzes all the motion modes and the transition configurations. Through these transition configurations, the mechanism can switch from one 1-DOF 7R mode to the 2-DOF double-Bennett mode and then to the other 1-DOF 7R mode.
