China has created a neural interface to control a robot in space with the power of thought

The research team of the Chinese space program announced the creation of a new interface

"brain-computer" for controlling robotichand on the space station. Previously, astronauts used a joystick and keyboard to control the robot. However, as scientists note, in conditions of weightlessness such control is not always convenient.

According to the developers of the device, earlierexisting control technologies using brain impulses did not have the necessary accuracy. Their efficiency ranged from 40% to 80%, which created a high risk of erroneous actions, unacceptable in the work of astronauts. The new development has shown in experiments an accuracy of over 99%.

To control the robot, a person usingneural interface, looks at the animated image on the computer screen. Each part of the robotic arm flashes at a unique rate. Sensors record changes in brain activity when a person's eye stops at a certain point. To improve the accuracy of brain wave recognition, scientists used AI.

Device testing with 35volunteers showed a control accuracy of 99.07%, scientists report. Moreover, even among 27 volunteers who had no experience in controlling a robotic arm, the results were almost as high - 98.9%.

“The neural interface is very easy to use,” the developers note. “Even an untrained person wearing our helmet demonstrates high precision and speed of control.”
