Design and Production of a 3D Printing Robot Hand with Three Underactuated Fingers

In this paper, we improve an underactuated finger mechanism, design a robot palm, and a three finger robot hand with the finger designed. Solidworks simulation is used to verify the rationality of the design. The parts of the hand are modified for 3D printing, and the prototype of hand is produced by 3D printing which can reduce the production process with low cost, designing flexibility and other advantages. Finally, we make some grasping experiments for the prototype. The results show that the robot can grasp the objects with different sizes, and verify the rationality of the design and the feasibility of making the robot hand by 3D printing.
