The paper presents a new parallel reconfigurable robot with six degrees of freedom and three guiding kinematic chains of the platform. A reconfigurable robot can change its structure in order to quickly adjust to production capacity and functionality. Using the virtual work method, this paper presents the workspace dynamics of the parallel reconfigurable robot. Some simulation results and some conclusions are presented at the end.  

Key words: reconfiguration, parallel robot, dynamic, virtual
