From robotics to optics and forgery prevention to solar cells, biomimicry has proven fertile ground for researchers. Recognizing nature's potential in the development of new technologies, DARPA has announced the establishment of the Biological Technologies Office (BTO), a new division that aims to "merge biology, engineering, and computer science to harness the power of natural systems for national security."  Read More

Jason Barnes and Professor Gil Weinberg demonstrate the robotic prosthesis

In 2012, Jason Barnes lost the lower part of his right arm after being electrocuted. Though he could have pursued his dream of becoming a professional drummer using only his remaining limb (like Def Leppard's Rick Allen, for example), he decided to build his own stick-wielding prosthesis. The attachment certainly allowed him to make some noise, but it wasn't flexible enough to give the speed or bounce control he was looking for. Now, thanks to the work of Georgia Tech's Professor Gil Weinberg, Barnes is preparing for a gig later this month where a novel robot drumming prosthetic arm will help him pound out precision rhythms with a live band.  Read More

Dennis Aabo Sørensen, using his sensory-enabled prosthesis

A man who lost his left hand in an accident nine years ago has had his sense of touch restored using a prosthetic hand surgically wired to nerves in his upper arm. During the trial Dennis Aabo Sørensen was able to grasp objects, detect the strength of grip, distinguish shape and identify objects by touch while blindfolded. The work was carried out by scientists from École Polytechnique Fédérale de Lausanne (EPFL) and Scuola Superiore Sant'Anna (SSSA).  Read More

A team of experts from various fields were able to develop a prosthetic arm that could be ...

While 3D printing technology has emerged to serve a wide variety of purposes, few appear more worthwhile than that of US-based company Not Impossible Labs. Through its Daniel Project, the company has not only provided 3D-printed prosthetic arms for amputees in war-torn Sudan, but empowered the local community to continue the initiative in its absence.  Read More

The avatar monkey used in the research – although the test monkeys saw its arms from a fir...

Recently there's been increasing hope for people who have lost the use of their arms, as various research institutes have started developing prosthetic arms that can be controlled by thought alone. So far, all of the systems have just allowed users to control a single arm – for many of the tasks that we perform on a daily basis, that's simply not enough. Now, however, scientists at North Carolina's Duke University have succeeded in getting two rhesus monkeys to control both arms of animated digital avatars, using nothing but their mind.  Read More

AMBER 2 is a robotic simulation of bipedal locomotion that closely mirrors a human gait

Bipedal robots have proved a challenging frontier for roboticists, with styles ranging from clunkers to lurchers to those seemingly falling over drunk. However, the AMBER lab at Texas A&M University has created universal mathematical functions of walking derived from human data and optimized for robotic systems. Their own proof of concept robots have strikingly human gaits and react appropriately to disturbances. Furthermore, the system has the potential to be applied to other bipedal robots to similarly upgrade their stride.  Read More

Experiments suggest that electrodes implanted in the sensory cortex of the brain can simul...

It's something most of us take for granted, but our sense of touch is every bit as useful to us as our sight and hearing. Though it seems simple, picking up and holding an object requires nearly instantaneous sensation in the parts of our hands and fingers in contact with the desired object, as well as a sense of the pressure we're applying. Many experimental efforts to simulate a sense of touch in amputees fitted with prosthetics require the subject to learn new associations between touching an object and some abstract sensation. But new research at the University of Chicago suggests that it is possible to map the individual finger pads of a prosthetic hand to the corresponding parts of the brain. In other words, prosthetic hands which offer a realistic sense of touch may theoretically be possible.  Read More

Easton LaChappelle demonstrates his prosthetic arm to President Barack Obama at the third ...

Advanced prosthetics have come a long way in the last few years, but the costs have also skyrocketed. A cheaper alternative may be on its way thanks to Easton LaChappelle, a 17-year old high school student from Colorado, who is using free online resources and the boom in inexpensive 3D printers to develop a functional prosthetic arm and hand. His projects have already earned him an invitation to the White House, and he's now working at NASA on the Robonaut team.  Read More

Buttercup poses with his 3D printed foot

Buttercup the duck was born with a strange birth defect. One of the little duckling's legs faced the wrong direction. To remedy the situation, 3D printing technology has been used to create a prosthetic leg that should allow Buttercup to live a somewhat normal, albeit much more famous, life.  Read More

A new bomb disposal robot developed at the Johns Hopkins University Applied Physics Laboratory (APL) is blurring the line between advanced prosthetics and robotics. Rather than building arms and hands from scratch specifically for the robot, the Bimanual Dexterous Robotics Platform (BDRP) is equipped with artificial limbs designed for amputees. The combination is relatively unique, and provided the team with a secondary use for the Modular Prosthetic Limb (MPL) it developed for the DARPA Revolutionizing Prosthetics program.  Read More
