Brain-machine interface helped a man with paralysis feed himself using robotic arms

In the future, people with arm paralysis might be able to feed themselves. A partially paralyzed man can use robotic arms to feed himself using a brain- machine interface. He only had to make small movements with his fists to get the fork and knife to cut his food. The researchers said he could have dessert in 90 seconds.

A shared control system reduces the amount of mental input needed to complete a task. He could use his four degrees of freedom of movement to control the robot arms. The workload was reduced by the prompt based intelligent responses of the limbs.

The technology isn't old. Touch-like sensory feedback is what scientists want to add. Reducing the need for visual confirmation is one of the things they hope to improve. The team sees robotic arms restoring complex movements and giving more independence to people with disabilities in the future.
