Simple grippers with one or two degrees of freedom are commercially available prosthetic hands; these pinch type devices cannot grasp small cylinders and spheres because of their small degree of freedom. This paper presents the design and prototyping of underactuated five-finger prosthetic hand for grasping various objects in daily life. Underactuated mechanism enables the prosthetic hand to move...
This paper discusses the development and control of the master-slave system capable of grasping an object with unknown coefficient of static friction. Partial slip information is known to be essential for conducting stable grasping in teleoperating system. The developed partial slip sensor contains strain gages in several ridges placed on the curvature contact surface of the elastic body. By measuring...
