Mind-controlled robots now one step closer

Tetraplegic patients are prisoners of their own bodies, unable to speak or perform the slightest movement. Researchers have been working for years to develop systems that can help these patients carry out some tasks on their own. "People with a spinal cord injury often experience permanent neurological deficits and severe motor disabilities that prevent them from performing even the simplest tasks, such as grasping an object," says Prof. Aude Billard, the head of EPFL's Learning Algorithms and Systems Laboratory. "Assistance from robots could help these people recover some of their lost dexterity, since the robot can execute tasks in their place."
