Myoelectric prosthetic hands provide an appearance with five fingers and a grasping function to forearm amputees. However, they have problems in weight, appearance, and cost. This paper reports on the Rehand, a realistic electric prosthetic hand created with a 3D printer. It provides a realistic appearance that is same as the cosmetic prosthetic hand and a grasping function. A simple link mechanism...
This paper discusses the developments and control strategies of exoskeleton-type robot systems for the application of an upper limb powered orthosis and an attachable power-assist device for care-givers. Hydraulic Bilateral Servo System, which consist of a computer controlled motor, parallel connected hydraulic actuators, position sensors, and pressure sensors, are installed in the system to derive...
Recent developments in shoulder powered prosthesis control can be divided into two types. The first type, as seen in development at Northwestern University, is depended on a myo-electrical signal replacement surgery in the chest area to allow the control of shoulder rotation, elevation, arm flexion and extension and the opening closing of the hand. On the other hand, our research focuses on using...
