Behold the Dexterity of the BeBionic3 Prosthetic Hand

By Norman Chan

"Terminator"-like arm has 14 grips that can be controlled with upper arms.

Nigel Ackland, a metals smelter who lost his arm six years ago in an industrial accident, has been testing the bebionic3, a myoelectric prostetic hand made by the British company RSLSteeper. Myoelectric prostetics detect electrical signals from the surface of the skin produced by voluntary muscle movement to control mechanical movement.

In the video above, Ackland demonstrates the impressive dexterity and range of movement offered by the carbon fiber hand, which allows him to perform tasks like typing, peeling vegetables, cracking eggs, and other everyday tasks. Up to 14 different grips are available to the user, with eight chosen at a time in custom software configurations. Bebionic 3 also has a grip strength of up to 31 pounds, and its fingers can bear the weight of 100 pounds in "hook mode". RSLSteeper launched the bebionic3 in September, after years of developing the hardware and software and testing with amputees. Price range from $25,000 to $35,000.
