Cheap 3D-printed bionic hand wins James Dyson Award, could bring robotic limbs to world
A robotics graduate has created new, far cheaper robotic hands — winning the UK James Dyson Award for an invention that uses 3D printing to transform the bionics industry.
The devices usually cost as much as £60,000 — but by using 3D printing and other techniques, 25-year-old Plymouth University graduate Joel Gibbard and his company Open Robotics have been able to slash that to only £3,000.
That could allow far more people to get the hands — which mostly use old technology, but remain out of reach for many because of their cost.
The economics of robotics will now work for children, who haven’t often been able to get them since the hands need to be replaced every six months to a year, and so aren’t viable. Even the most expensive ones for adults tend to need to be replaced every three to five years, because of wear and tear.
It could also help the technology to get more internationally widespread, helping them overcome the price barriers in other countries where bionic hands have been simply too expensive to use.
“By using rapid prototyping techniques, Joel has initiated a step-change in the development of robotic limbs,” James Dyson, the British inventor behind the award, said in a statement. “Embracing a streamlined approach to manufacturing allows Joel's design to be highly efficient, giving more amputees’ access to advanced prosthetics.”
The hands work by connecting into the muscles in the upper forearm. Myoelectric sensors are used to take messages from the muscles and uses them to control the hand.
Gibbard’s innovation is using 3D printing — first, the arm is scanned, and then the hand can be custom printed to fit. That means that they can be precisely created for whoever is wearing them, but at a fraction of the usual cost.
The same technology could eventually come to be used in most things that people wear, Gibbard predicts.
“This has tons of applications, like prosthetics and orthotics,” which are used for modifying the neuromuscular and skeletal system, says Gibbard. “But also earphones, or any other wearable, should be custom fitted.
“Even a phone could be custom fitted to your hand. There are so many things where we use a standardised thing, where in reality, a customised thing would be better.
“You can imagine a world in the future where you scan your whole body in — and then use it whenever you buy clothes, or a desk chair,” with the manufacturers custom making it around a person’s scan.
Gibbard has been working on prosthetic hands since he was 17, initially considering it “just as a fun thing to do”. But once he’d arrived at university and took on the project more seriously, he found there was a need that wasn’t being fulfilled, for cheap prosthetics that could be more easily made and bought.
A video of his proposal was uploaded to YouTube. “I had tons of comments, saying: I need this, I want to buy this,” says Gibbard. “At that point I realise that I wanted to share the idea and designs further.”
That interest helped spur interest in a crowdfunding campaign — titled “The Open Hand Project: A Low Cost Robotic Hand” — that raised almost £44,000 in one month.
Initially Gibbard’s plan was to make a 3D printable design, which could then be shared across the world so that anyone, anywhere could make them. But he realised that a company — which could ensure quality control, guarantee its products and ensure that they work well — would be a better way of getting the new product out into the world, and he founded his firm Open Bionics in April 2014.
From now, the company has both technological and business hurdles that it needs to overcome.
First, the product needs to be tested in the real world — it has already been worked on with several amputees, but now those tests must move out into the field, letting people use them for a few weeks and provide feedback on what they’re like.
There is business work to do, too. Gibbard’s company will use the money from the award to buy another 3D printer, meaning that they will be able to increase their production substantially straight away — printing twice as quickly and therefore doing more field testing, and faster.
But Gibbard says that the award will help as the company goes onto grow, too. “The James Dyson award comes with such huge prestige, that when you’re trying to get funding and credibility, it’s a massive, massive boost.”
Open Bionics currently has six members of staff, enough to keep working on the project for the moment. But by the time that it comes to market — which is set to happen before the end of 2016 — the staff and resources will need to grow.
Joel Gibbard and Open Bionics will join the rest of the UK runners up to move onto the next stage of the James Dyson Award, where Dyson engineers whittle down the list of 100 to 20. That will then be passed onto Dyson himself, who will pick the overall winner.

/ About us
Founded by Russian entrepreneur Dmitry Itskov in February 2011 with the participation of leading Russian specialists in the field of neural interfaces, robotics, artificial organs and systems.
The main goals of the 2045 Initiative: the creation and realization of a new strategy for the development of humanity which meets global civilization challenges; the creation of optimale conditions promoting the spiritual enlightenment of humanity; and the realization of a new futuristic reality based on 5 principles: high spirituality, high culture, high ethics, high science and high technologies.
The main science mega-project of the 2045 Initiative aims to create technologies enabling the transfer of a individual’s personality to a more advanced non-biological carrier, and extending life, including to the point of immortality. We devote particular attention to enabling the fullest possible dialogue between the world’s major spiritual traditions, science and society.
A large-scale transformation of humanity, comparable to some of the major spiritual and sci-tech revolutions in history, will require a new strategy. We believe this to be necessary to overcome existing crises, which threaten our planetary habitat and the continued existence of humanity as a species. With the 2045 Initiative, we hope to realize a new strategy for humanity's development, and in so doing, create a more productive, fulfilling, and satisfying future.
The "2045" team is working towards creating an international research center where leading scientists will be engaged in research and development in the fields of anthropomorphic robotics, living systems modeling and brain and consciousness modeling with the goal of transferring one’s individual consciousness to an artificial carrier and achieving cybernetic immortality.
An annual congress "The Global Future 2045" is organized by the Initiative to give platform for discussing mankind's evolutionary strategy based on technologies of cybernetic immortality as well as the possible impact of such technologies on global society, politics and economies of the future.
Future prospects of "2045" Initiative for society
2015-2020
The emergence and widespread use of affordable android "avatars" controlled by a "brain-computer" interface. Coupled with related technologies “avatars’ will give people a number of new features: ability to work in dangerous environments, perform rescue operations, travel in extreme situations etc.
Avatar components will be used in medicine for the rehabilitation of fully or partially disabled patients giving them prosthetic limbs or recover lost senses.
2020-2025
Creation of an autonomous life-support system for the human brain linked to a robot, ‘avatar’, will save people whose body is completely worn out or irreversibly damaged. Any patient with an intact brain will be able to return to a fully functioning bodily life. Such technologies will greatly enlarge the possibility of hybrid bio-electronic devices, thus creating a new IT revolution and will make all kinds of superimpositions of electronic and biological systems possible.
2030-2035
Creation of a computer model of the brain and human consciousness with the subsequent development of means to transfer individual consciousness onto an artificial carrier. This development will profoundly change the world, it will not only give everyone the possibility of cybernetic immortality but will also create a friendly artificial intelligence, expand human capabilities and provide opportunities for ordinary people to restore or modify their own brain multiple times. The final result at this stage can be a real revolution in the understanding of human nature that will completely change the human and technical prospects for humanity.
2045
This is the time when substance-independent minds will receive new bodies with capacities far exceeding those of ordinary humans. A new era for humanity will arrive! Changes will occur in all spheres of human activity – energy generation, transportation, politics, medicine, psychology, sciences, and so on.
Today it is hard to imagine a future when bodies consisting of nanorobots will become affordable and capable of taking any form. It is also hard to imagine body holograms featuring controlled matter. One thing is clear however: humanity, for the first time in its history, will make a fully managed evolutionary transition and eventually become a new species. Moreover, prerequisites for a large-scale expansion into outer space will be created as well.
