<p>This paper is described about the design and operation evaluation of the skeleton type electric prosthetic hand for mass production purpose. Through changing an electric motor unit from a servomotor to a linear step motor in order to reduce power consumption against the previous prosthetic hand [4] [5] and through changing the initial shape of the glove were achieved. Then a user-evaluation was performed in order to check grip shape against various forms of objects. It was confirmed that the new prosthetic hand can realize various grips according to objects with various shaped as like as previous skeleton type prosthetic hand.</p>
