This can only lead to a summer blockbuster. Researchers implanted tiny electrodes in two monkeys’ brains, allowing them to move robotic arms with their thoughts.
To motivate the monkeys to perform, they were encouraged to feed themselves marshmallows and pieces of fruit with the robotic arms, which had joints and “grippers” that roughly replicated fingers. According to the research team’s report in Nature [subscription required], the arms’ movements were fluid and natural, and the monkeys continuously adjusted the speed and direction of their robotic limbs.
While the technology isn’t yet ready for human testing, scientists are hopeful that it can eventually be applied to prosthetic limbs for people with spinal cord injuries, strokes, and other paralyzing conditions.
