A group of researchers at Sandia National Laboratory in the United States produced a mechanical hand with looking reproduce the skill of the human hand, while maintaining a simple design that avoids emulating the bones, joints and ligaments, opting for plastic modular system whose e is largely made cell phone parts.

Thanks to this, Sandia engineers estimate that the hand would cost only about $10,000, a fraction of the cost of a modern arm that can reach $250,000. A very affordable price since its purpose is to be used by the army to defuse bombs.

The fingers are glued to the main mechanism by magnets, giving researchers the flexibility to design interchangeable appendages with various tools such as screwdrivers, flashlight, cameras or other tools. They are also designed to fingers loosened by impact alone to avoid damage. In addition, only 4 fingers, since the researchers this amount sufficient to perform a wide range of handling tasks.

The hand does not currently operate independently and must be controlled by a human operator via a USB cable (although there are ways to handle wireless). The researchers’ goal now is to develop a glove to manipulate the not exceeding $1,000.
