This modified Roomba avoids users when it detects high levels of stress. Which is good for it because otherwise it would just be willing to take your abuse if you’re the sick sort that kicks puppies, cute kitties and helpless roombas.
It was designed by researchers at the University of Calgary, who interact with the bot via a headband for gamers that detects how much muscle tension is in your face. The more tension, the more space the Roomba will put between itself and you. The idea is to explore human and machine interaction on an emotional level.
