Carbon Fibre Robotic Arm

This prosthesis is called the BeBionic3 myoelectric hand and it’s made by a British company named RSLSteeper

About six years ago, Nigel Ackland lost half of his arm in an unfortunate work accident. And now rather than sporting a typical, silicon, prosthetic hand that mimics human flesh, Ackland is sporting the Terminator look.

The BeBionic3 is far beyond your typical prosthetic arm and allows for more control and greater grips. It is made with a full carbon fibre body and has aluminum and alloy knuckles. The hand works from sensors on both sides of his arm and once activated, can be controlled by two muscles. It comes with eight different programmed grips which allow him to point a finger, type on a keyboard, hold a mouse and much more…like scaring children with a “come here” motion. You can see what I mean in the video below. The thumb position can also be moved around, to allow for more reach and grab. While there is no exact word on price yet, you can expect it to go for a pretty penny. But it will hopefully be covered by most insurance and Medicare in the U.S. and the national healthcare in the U.K.


Also from the video, you can see that the BeBionic3 is gentle enough to grab eggs from a carton yet powerful enough to hold onto a nice cold beer. It’s also obvious from the video, Ackland considers himself extremely fortunate to have been given such an awesome second chance at having a hand.

Make sure to check out the videos below to see for yourself. It truly is amazing how far prosthetic have come, thanks to carbon fibre and technology.



What is Carbon Fibre?

A carbon fibre is a long, thin strand of material about 0.0002-0.0004 in (0.005-0.010 mm) in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fibre. The crystal alignment makes the fibre incredibly strong for its size. Several thousand carbon fibres are twisted together to form a yarn, which may be used by itself or woven into a fabric. The yarn or fabric is combined with epoxy and wound or molded into shape to form various composite materials. Carbon fibre-reinforced composite materials are used to make aircraft and spacecraft parts, racing car bodies, golf club shafts, bicycle frames, fishing rods, automobile springs, sailboat masts, and many other components where light weight and high strength are needed.

Carbon fibres are classified by the tensile modulus of the fibre. The English unit of measurement is pounds of force per square inch of cross-sectional area, or psi. Carbon fibres classified as “low modulus” have a tensile modulus below 34.8 million psi (240 million kPa). Other classifications, in ascending order of tensile modulus, include “standard modulus,” “intermediate modulus,” “high modulus,” and “ultrahigh modulus.” Ultrahigh modulus carbon fibres have a tensile modulus of 72.5 -145.0 million psi (500 million-1.0 billion kPa). As a comparison, steel has a tensile modulus of about 29 million psi (200 million kPa). Thus, the strongest carbon fibres are ten times stronger than steel and eight times that of aluminum, not to mention much lighter than both materials, 5 and 1.5 times, respectively. Additionally, their fatigue properties are superior to all known metallic structures, and they are one of the most corrosion-resistant materials available, when coupled with the proper resins.

Thirty years ago, carbon fibre was a space-age material, too costly to be used in anything except aerospace. However today, carbon fibre is being used in wind turbines, automobiles, sporting goods, and many other applications.
