Researchers at MIT's Computer Science and Artificial Intelligence Lab (CSAIL) and Boston University have created a system where humans can guide robots with their brainwaves. For now, the MIT system can only handle simple activities, but the researchers see a future where one day we could control robots in more natural ways, like allowing an operator on a factory floor to control a robot without ever pushing a button. “Imagine you look at the robots, and at some point one robot is not doing the job correctly,” CSAIL Director Daniela Rus explained. “You will have that thought, and through this detection you would in fact communicate remotely with the robot to say ‘stop’.” Rus admits the MIT development is a baby step, but she says it's an important step toward improving the way humans and robots interact.

The MIT paper shows it's possible to have a robot read your mind—at least when it comes to a very simple task. And this system could one day help people who can't communicate orally, says Andres Salazar-Gomez, a Boston University PhD candidate working with the CSAIL research team.

In this study, researchers at the Massachusetts Institute of Technology used a robot named Baxter who was a volunteer wearing an EEG cap that could read electrical activity in the brain. If he noticed a mistake, he would naturally send out a brain signal known as an “error-related potential”.

“You can use that signal to tell a robot to stop or you can use that to change the action of the robot,”Rus explained.

The system then translates that brain signal to Baxter, so he understands he's wrong. His cheeks turn red to show he's embarrassed, and he corrects his behavior.

The MIT system corrected the robot's behavior 70 percent of the time.

Rus imagines a future where anybody can communicate with a robot without any training. “Imagine you have your robot pick up and sort all the toys and socks from the floor,” she said. She says that would save her a lot of time, but for now the mechanical house cleaner that can read your mind is still a dream.
