Mind-controlled robot avatars inch towards reality

Researchers at the CNRS-AIST Joint Robotics Laboratory (a collaboration between France's Centre National de la Recherche Scientifique and Japan's National Institute of Advanced Industrial Science and Technology) are developing software that allows a person to drive a robot with their thoughts alone. The technology could one day give a paralyzed patient greater autonomy through a robotic agent or avatar.

The system requires that a patient concentrate their attention on a symbol displayed on a computer screen (such as a flashing arrow). An electroencephalography (EEG) cap outfitted with electrodes reads the electrical activity in their brain, which is interpreted by a signal processor. Finally, the desired command is sent to the robot to carry out.

The system does not provide direct fine-grain motor control: the robot is simply performing a preset action such as walking forward, turning right or left, and so on. The robot's artificial intelligence, developed over several years at the lab, allows it to perform more delicate tasks such as picking up an object from a table without needing human input. In this scenario, the robot's camera images are parsed by object recognition software, allowing the patient to choose one of the objects on a table by focusing their attention on it.

With training, the user can direct the robot's movements and pick up beverages or other objects in their surroundings. The system can be seen in use in the DigInfo video at the bottom of the page.

This is similar to but more sophisticated than previous projects, one involving Honda's ASIMO robot from 2006, and another at the University of Washington from 2007.

A different but more direct approach would be to track a patient's eye movements. Recent research conducted at the Universit

I can see this having a military use too.
