【Abstract】 A novel three degree of freedom parallel manipulator with only translational degrees of freedom is presented.The main advantage of this parallel manipulator is that it does not need any additional link structure to keep moving platform translational,which reduces the possibility of interference of links.Closed\|form solutions for both the forward and inverse kinematics problems are developed,which can help to fabricate a prototype to demonstrate this manipulator.更多还原
