A new prosthetic system allows amputees to feel familiar sensations and also, somewhat unexpectedly, reduces their phantom pain. Researchers at Case Western Reserve University and the Louis Stokes Cleveland Veterans Affairs Medical Center developed the system to reactivate areas of the brain that produce the sense of touch, but recipients of prosthetic hands reported their phantom pain subsiding almost completely after being hooked up to the system.  Read More

Gizmag gives TMR Designs' Imprint Grips a try

Whether you're pounding over rocks and roots or flying down a steep descent, you definitely don't want your hands to be slipping off your mountain bike's handlebar grips. With that in mind, UK-based TMR Designs recently set about designing grips that could be custom-molded to the size and shape of an individual rider's hands. After a successful Kickstarter campaign, the resulting Imprint Bicycle Grips are now in production. I got my hands on a pair – literally – to find out if they really make a difference.  Read More

Faye Wu uses the supernumerary robotic fingers

Earlier this month, we heard about an MIT project in which test subjects were equipped with an extra set of robotic arms in order to help them perform tasks. While the technology is certainly intriguing, some people might find the concept of a four-armed cyborg to be a little ... much. If you're one of those people, then you might be more comfortable with another ongoing MIT project. It's just aimed at giving people two extra robotic fingers.  Read More

Touch Bionics has unveiled the latest enhancements to its i-limb Ultra Revolution at OTWorld 2014 International Congress. Users can now set and assign different grips for different objects and configure the prosthetic hand via Android apps.  Read More

Electrical contacts located in the fingertips deliver short electrical pulses, stimulating...

While we can counter the deterioration of sight and hearing with glasses and hearing aids, few tools exist for combating a degenerating sense of touch. A common ailment among stroke patients and the aging, treating diminishing tactile perception has proven a complicated task. Looking to provide a wearable solution unimposing enough for everyday use, a research team from Germany's Ruhr University Bochum (RUB) is developing a stimulation glove designed to be worn passively to alleviate such impairments.  Read More

The Ishikawa Oku Lab's robot hand sticks out two fingers (scissors), beating the human (pa...

Remember that high speed robot from last year, that could beat humans at rock, paper, scissors? Since then, researchers at the University of Tokyo's Ishikawa Oku Lab have continued to work on it. The result? Well, they couldn't really improve its accuracy beyond 100 percent, so instead they made it faster.  Read More

DARPA's ARM program hand is flexible enough to pick up a basketball...

Back when DARPA first announced its Autonomous Robotic Manipulation (ARM) program in 2010, the average cost of a military-grade robot hand was around US$50,000. That's expensive even by the US military's standards – especially for something that is bound to be in close contact with explosives – which is why the hardware team of the ARM program tasked participants with developing a reliable low-cost hand. Now, thanks to work by iRobot (yes, the company that makes the Roomba robotic vacuum) and researchers at Harvard and Yale, the ARM program has a surprisingly effective new hand to play with that costs just $3,000 (in batches of 1,000 or more).  Read More

The i-limb is controlled by a smartphone app

Whichever marketing genius came up with the Apple catchphrase, "There's an app for that," has a lot to answer for – or brag about. It's heard so often these days that it’s become a cliché. Touch Bionic’s i-limb ultra revolution robotic artificial hand gives yet another reason to repeat the phrase. It’s linked to a smartphone app, which allows for greater control of the hand, including the ability to program it to suit the wearer’s personal needs.  Read More

Liam impressed his doctors and classmates alike with his 'Robohand,' which was created by ...

According to the International Society of Prosthetics and Orthotics (ISPO), there are some 32 million amputees in the world today, around 80 percent (25 million) of whom live in developing countries where only five percent have been fitted with an artificial limb. It is estimated that 200,000 people lost a limb as a result of the 2010 Haiti earthquake alone. Two low-cost, printable prostheses highlight the potential impact 3D printing could have on the quality of life for millions as the technology becomes more accessible around the world.  Read More

iRobot tests the durability of its new robot hand by smashing it with a baseball bat

Not even a baseball bat can damage the fingers of a new robotic hand developed by iRobot for the DARPA Autonomous Robotic Manipulation (ARM) program. The four-year program, which began in 2010, seeks to build and program a robot capable of handling all kinds of things on the battlefield with minimal human input. Most robot hands have rigid components which tend to be quite fragile, but this hand has rubbery fingers, which are better able to absorb impacts.  Read More
