Prosthetic hand with a simple driving system

The intricate and complex bio-mechanics of the human hand provides humans with the ability to grasp objects in various ways and interact with the natural environment. The simple act of writing a name or tying the shoes may seem like a tedious task to most, but to a person who has lost a hand, even the simplest of tasks become impossible. While there have been many attempts to recreate the human hand especially with the fast advancement of science and technology and the functionality of prosthetic hands have been improved dramatically, few such prosthetics provide an adequate substitute for a price that ordinary amputees can afford. There is a need for a prosthetic hand that is both practical and affordable. This research aimed to develop a prototype prosthetic hand that meets the requirement of ordinary amputees and has the expected basic functionality. With the consultation from key beneficiary and right hand amputee, the prototype was required to be able to carry up to 10kg weight and compatible with a driving system that has been used by amputees for many years, allowing a proven prototype to be quickly developed into a product ready for the market place.
