The SDM Hand as a Prosthetic Terminal Device: A Feasibility Study

In this paper we discuss the potential of applying our concept for a robotic hand fabricated via Shape Deposition Manufacturing (SDM) as a prosthetic terminal device. Experimental results with the hand have shown a level of robustness, adaptability, and other performance properties as yet unseen in a robotic hand. Besides reliable performance, the hand is durable, is produced using a molding process that allows both for inexpensive mass production as well as a realistic appearance without the need for a cosmetic glove, and incorporates a simple design that requires only a single actuator for the eight active degrees of freedom. All of these factors make it a good candidate as a basis for either a body-powered or externally-powered prosthetic terminal device that is realistic, functional, robust, and inexpensive.
