Researchers have developed a robot which uses brainwaves to control its actions. The robot requires a human to wear an electroencephalography cap, which monitors the brain activity. It monitors the brain for specific signals, and this is how the robot is controlled. The actions that the robot carries out happens almost at the same time as the brain signals are detected, and when the person realises the robot is making a mistake, it is picked up through the brain signals and the actions change just about at the same time.
The system used relies on the brain signals which are sent when a mistake is noticed and during a trial which took place, the researchers used an industrial robot and found that the robot picked up on the brain signals between ten and thirty milliseconds after the signal was sent in the brain. During the trial, the robot used brainwaves in order to perform simple tasks such as sorting cans of paint and wire into different boxes.
While the robot is successful so far in completing the tasks, there is still more developing needed in order to progress it and make it a lot more accurate.
