A team of four mechanical engineering students from the University of Pennsylvania has won the 2013 James Dyson Award for producing a prosthetic hand called the Titan Arm.
The battery-powered robotic arm can augment human weight-lifting strength by 40 pounds (18 Kg). The team also wanted it to be affordable; hence they used cheap aluminium to construct most of its structural parts. Currently, Titan Arm is remotely controlled by a joystick but they hope that in future they can develop models that use electromyography technology. This will enable the user to directly control the prosthetic arm using electrical signals produced in his muscle tissues.
