The MIT has designed a humanoid robot dubbed Baxter, it can read your mind and respond to a thought if it is getting a given job or task right or wrong.

Baxter requires a human participant to wear an electroencephalography (EEG) monitor that records brain activity and can tell when that person thinks it is s------g up as it sorts objects. The robot can be shamed without even opening your mouth.

MIT set out to design a system that could actually respond to a person’s more natural, automatic responses to a robot’s actions. Specifically, Baxter focuses on brain signals called “error-related potentials” (ErrPs) that our minds generate whenever we notice a goof.

According to the director of MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL), Daniela Rus, “As you watch the robot, all you have to do is mentally agree or disagree with what it is doing. You don’t have to train yourself to think in a certain way — the machine adapts to you, and not the other way around.”

Baxter is actually a multi-purpose robot from Rethink Robotics designed for industrial automation that MIT researchers hooked up to their mind-reading algorithm.

Right now Baxter can only handle binary “right or wrong” activities, but the research team thinks it could also be possible to control multiple-choice tasks via thought. Eventually, the system could be a foundation for fully controlling robots in more intuitive ways.

“Imagine being able to instantaneously tell a robot to do a certain action, without needing to type a command, push a button or even say a word,” Rus said. “A streamlined approach like that would improve our abilities to supervise factory robots, driverless cars and other technologies we haven’t even invented yet.”

This is a very wonderful invention, I believe it still needs proper security check to avoid the algorithm being altered and the robot abused.

One day the robot will give u a hard blow, for getting angry always and thinking it screws up on all task.
