The poster is about a selection registration named Charming Students.

Scientists have created a way to control a robot with signals from a human brain.

By generating the proper brainwaves―picked up by a cap with e-lectrodes (电极) that sense the signals and reflect a person's instruc?tions―scientists can instruct a humanoid robot to move to specific locations and pick up certain objects.

The commands are limited to moving forward,picking up one of two objects and bringing it to one of two locations. The researchers have achieved 94 per cent of accuracy between the thought commands and the robot's movements.

"This is really a proof-of-concept demonstration,"said Rajesh Rao,a researcher from the University of Washington who leads the project. "It suggests that one day we might be able to use semi-autonomous robots for such jobs as helping disabled peo?ple or performing routine tasks in a person's home.” The person wearing the electrode cap watches the robot's movement on a com?puter screen through two cameras installed on and above the robot.

When the robot's cameras see the objects that are to be picked up,they pass on the information to the user's computer screen. Each object lights up randomly on the computer screen. When a person wants something to be picked up and i[ hap?pens to light up,the brain registers surprise and sends this brain activity to the com?puter and then to the robot. The robot then proceeds to pick up the object.

A similar programme is used to decide where the robot will go.

"One of the important things about this demonstration is that we're using a 'noisy' brain signal to control the robot, "Rao said. "That means we can only obtain brain signals indirectly from sensors on the surface of the head,and not where they are generated deep in the brain. As a result,the user can only generate high-level commands such as indicating which object to pick up or which location to go to,and the robot needs to be autonomous enough to be able to execute such commands.” In the future,the researchers hope to make the robot more adaptive to the en?vironment by having them carry out more complex commands.
