Abstract

The control of the Touch Hand: a low-cost electrically powered prosthetic hand is explored in this paper. A novel Haptic User Interface is proposed and tested as a supplement for amputee-prosthetic EMG control. The performance of the prosthetic hand is tested through gripping tests. The hand is capable of performing a lateral grip of 3.7 N, a power grip of 19.5 N and to passively hold a weight of up to 8 kg with a hook grip. The hand is also tested on an amputee and used to perform basic tasks. The amputee took 30 min to learn how to operate the hands basic gripping functions.
