Researchers create first mind-controlled robot arm that works well without surgery

Carnegie Mellon researchers working with peers from the University of Minnesotahave made a big breakthrough in brain-computer interface (BCI) and robotic technology: They’ve developed a way for a person to control a robot arm with their minds — with no surgery or invasive procedures required to make it possible.
The mind-controlled robot in this experiment also showed a high degree of motor control, as it’s able to track a computer cursor as it moves across a screen. This is ob
