The typical prosthetic limb is a very limited device that usually looks very little like the arm, hand or leg it is meant to replace.
A new touch-activated system projects onto walls and other surfaces and can recognize hand posture and gestures to identify individual users.
Researchers at Newcastle University and Microsoft Research Cambridge (MSR) have developed a wrist controller which allows the user to remotely control any device without any extra hardware.
Sandia National Laboratories has built a robotic hand designed for disarming improvised explosive devices, or IEDs, that's so flexible it can even repair itself.
Surgeons at Washington University School of Medicine in St. Louis have re-routed nerves in the upper arm to restore some hand function in a quadriplegic patient.
For years, robotics engineers have worked on creating robot hands that can grip like the real thing. But it turns out that all they needed was some ground coffee and a party balloon.
