A young engineer based near Bristol has designed and built a prototype bionic hand in his bedroom.
Roboticist Joel Gibbard, 23, developed the prosthetic using parts made on a home 3D printer.
He hopes the project, details of which will be made freely available online, could lead to a low-cost bionic hand for amputees.
