Third Arm: Wearable Robotic Limb

Here is a robot that gives you a third arm. Developed by Georgia Institute of Technology researchers, this robotic arm allows musicians to play with three arms. The two-foot long smart arm can be attached to a musician’s shoulder and respond to gestures or the music it hears. It also adapts to its environment.

As the researchers explain, the next step is to link this wearable robotic limb to brain activity. More information is available here.
