Abstract: This paper presents a new concept of torque balancer for reducing the input torque fluctuation of a mechanism. The proposed active gear balancer consists of a differential gear train and a ...

Abstract: A novel 8U (universal joint) parallel mechanism, being able to do omnidirectional rolling motion is proposed in this paper. This mobile mechanism owns the priority of simple structure and rolling ...

Abstract: A family of biped spatial four-link mechanisms with two revolute and two cylindric joints is proposed in this paper. Three main categories, including eight configurations are put forward. The ...
