Monkey Controlled Robot Reaches New Level Of Complexity

monkey brain robotIn a remarkable demonstration of brain-machine interface technology, researchers at the University of Pittsburgh have taught a monkey to use just its thoughts to control an advanced robotic arm and perform elaborate maneuvers with it.

It's not the first time a monkey with sensors implanted in its brains has controlled machines with its mind. But this seven-degrees-of-freedom robot arm is probably the most complex system a monkey has ever mastered with its thoughts alone.

Researchers have long been working to put the brain in direct communication with machines. The hope is one day brain-machine interfaces will allow paralyzed people to operate advanced prosthetics in a natural way. Recent demonstrations have seen animals and humans controlling ever more complex devices.

But the experiments at the University of Pittsburgh, led by Dr. Andrew Schwartz, a professor of neurobiology, appear to involve an unprecedented degree of complexity in terms of the robotic arm, the level of control, and the difficulty of the manipulations demonstrated.
