Brain Signals Control a Robotic Arm in Three Dimensions
Two people with tetraplegia used implanted interfaces to reach for and grasp objects, moving BCI control from a screen into the physical world.
BrainGate collaboration / Brown University One participant used the robotic arm to lift a bottle and drink, an activity she had not performed independently for nearly 15 years. The experiment showed that motor-cortex signals remained useful long after injury, while also exposing the gap between a supervised laboratory demonstration and an autonomous home device.
