? The Dextrus hand is a working prototype resulting from 23-year- old
Dextrus is a fullyfunctional robotic hand, with features and capabilities similar to leading advanced prosthetics but at a fraction of the cost.
The hand works much like a human hand. But it uses electric motors instead of muscles and steel cables instead of tendons. 3D- printed plastic parts work like bones, and a rubber coating acts as the skin. All of these parts are controlled by electronics to give the hand a natural movement that can handle all sorts of objects.
The hand can be connected to an existing prosthesis. It uses stick-on electrodes to read signals from the remaining muscles. The fingers are individually powered and each can sense when an object is impeding its movement, giving it the ability to grasp objects gently. It means the fingers can really wrap around unusual shapes to grip them firmly. Costs have been cut in a number of ways, from using cheaper materials in the construction, to 3D-printing component parts.
