Abstract: In this paper, an analytical approach for the displacement analysis of spatial openloop systems by means of direction cosine transformation matrices is presented. Two local coordinate systems at ...

Abstract: A method of displacement analysis of the four-link spatial mechanism is developed. The results through this analysis will be exact solutions that can be obtained without resorting to numerical ...

Abstract: This paper presents a new closed-form resolution scheme of the forward kinematics of parallel manipulators based on two concepts, local structurization and mechanism partition. This scheme is ...

Abstract: In this paper, we describe the stiffness of a grasp as a function of grasp configuration, grasp forces and joint stiffness of the fingers. The effects caused by the change of joint configuration ...
