First non-invasively mind-controlled robotic arm


Researchers from Carnegie Mellon University developed the first mind-controlled robotic arm without brain implants. According to the scientists, non-invasively controlled robotic devices would benefit paralyzed patients as well as those with movement disorders and might someday become an assistive technology for everyone. They exhibited their new technology with a robotic arm able to continuously track a computer cursor. Brain-computer interfaces controlled by signals from brain implants had performed well before. These, however require considerable medical expertise and have medical and surgical risks. Previously, non-invasively controlled robotic arms had only followed the cursor in erratic discrete motions. Now, the arm follows the cursor in a smooth way.
