Brain-machine interface lets monkey control two robotic arms

In February, Duke scientists announced a brain-machine interface that allowed a rhesus monkey to control a single robotic arm more than 7000 miles away. Today, they've expanded on the previous experiment, announcing an improved interface that allows for independent control of two arms, assimilating both mechanical arms into the monkeys' existing motor control systems.

Similar to the previous experiments, the experiment set up two rhesus monkeys in front of a remote video link, while implants monitored nearly 500 neurons to pick up motion signals. After some training, the monkeys were trained to cover targets on the screen with the arms, proving the subjects had c...
