Ever wanted to have an avatar like in the movie? Well, news has come in that for the first time a robot has been controlled purely by thought. The person had to lie in an fMRI machine and think about the motions required of the robot. Of course this is still just a first step and is a long way from guiding a flesh surrogate body as it runs, jumps, and swings through the forests of Pandora. But the advance does give hope that people who are immobile, such as those with locked-in syndrome, will be able to interact with their environment one day. Here’s a video from New Scientist showing the robot in action.
