This paper describes a tentative results obtained on the way of developing the nano order precision robot that works with the resolution of 10nm or less. For precision positioning of robot manipulator, we adopt the flexure hinge mechanism composed with notches and holes that allows high stiffness and easy applications to construct the parallel manipulator. As a hardware for in plane motion of manipulator...
In this paper, CaPaMan2bis (Cassino parallel manipulator version 2bis) has been analysed as trunk subsystem in CALUMA (Cassino low-cost humanoid) robot. Dynamic simulations have been developed for an operation of CaPaMan2bis as trunk module of CALUMA has been checked. Specifically, simulations for walking and grasping have been carried out to evaluate CALUMA performance. Simulations have given results...
This paper presents a simple numerical method for forward kinematics of a general 6-DOF parallel manipulators, which can generate a unique solution directly. This method utilizes the trivial nature of the inverse kinematics of parallel manipulators, and derives a straightforward linear relationship between the small change of joint variables (leg lengths) and the resulting small motion of the platform...
This paper is introducing a prototype of a novel 6 DOF parallel robot POLMAN-3times2 dedicated for fast manipulation. In the manipulator design the special motion transmission mechanisms was applied bringing a dynamic decoupling. Robot has an unique kinematics structure. Adequate selection of link lengths and design of mass distribution resulted in good kinematic properties (e.g. large workspace)...
In this paper, a novel approach to the identification of instantaneous and continuous motions of a constrained rigid body is proposed by employing the concept of constraining-power rate. With the investigation into the constraining-power rate of a general constrained rigid body, the sufficient and necessary conditions of continuous motion of a general constrained rigid body are firstly presented....
