The field of robotic has been advancing by leaps and bounds in recent years, especially where robotic limbs and prosthetics are concerned. But until recently, cost has remained an issue. With top of the line bionic limbs – like the BeBionic which costs up to $35,000 = most amputees simply can’t afford them. Little surprise then why there are many efforts to create robotic limbs that are both cheaper and more accessible.
Last month, DARPA announced the creation of a robotic hand that could perform complex tasks, and which was made using cheap electronic components. And then there’s Robohand, the online group that creates 3D-printed robotic hands for children with a free, open-source 3D-printing pattern available on Thingiverse for people who wish to make their own.
And now, Christopher Chappell of the U.K. wants to do take things a step further with his “Anthromod”. Using Kickstarter, a crowdfunding website, he has started a campaign for a 3D-printed robotic hand that is a little bit more sophisticated than the Robohand, but would cost around $450. In short, the proposed design offers the ambulatory ability of a bionic limb, but at a cost that is far more affordable.
To break it down, the arm uses a tendon system of elastic bands with the movement being provided by five Hobby Servos, which are in turn built out of off-the-shelf electronics. Wearers will be able to move all four of the units fingers, thumb and wrist, once the sensors have been calibrated, and the software to control the hand and EEG sensors is available online for free. This all adds up to a unit that is not only more affordable, but easy to assemble, repair and maintain.
On their Kickstarter page, Chappell describes his campaign and their long-term goals:
Our Kickstarter campaign is to develop a humanoid robotic hand and arm that is of far lower cost than any other available. We believe that this will open up robotics to a far wider market of makers and researchers than has ever been possible. This should then trigger an explosion of creativity in the areas of robotics, telepresence and ultimately prosthetics.
Much like the InMoov, a 3D printed android with limited function, the Anthromod represents an age of robotics that are accessible to the public. And with time, its not hard to imagine an entire line of enhancements and robotics, such as household servants and cybernetic components, that could be manufactured in-house, provided you’re willing to shell out the money for a industrial-sized 3D printer!

Note: As of this article’s writing, Chappell and his colleagues passed their goal of £10,000 and reached a whopping total of £12,086 (18,808 dollars US). Congratulations folks!
