A look at what – and who – is pushing the future in new directions

Robot Love

Scientists from the University of Hertfordshire recently unveiled Nao — the first robot allegedly capable of both developing and expressing emotions. This sensitive robot is the result of Feelix Growing (Feel, Interact, Express), a project aimed at socially situating robots in our society. According to Dr. Lola Cañamero, the computer scientist who is running the project, “Emotions foster adaptation to environment, so robots would be better at learning things.”

Nao is the emotional equivalent of a one-year-old child, showing emotion through non-verbal clues like posture and gestures, rather than more advanced facial or verbal expression. Non-verbal clues from actual human beings, body language and distance in particular, are also what guide Nao’s reactions and feelings. The robot learns from human interactions, can remember faces and is programmed to form close bonds with people who treat it (him? Pronoun struggle.) with kindness. This basic understanding of human body language, along with a programmed set of basic rules about what’s “good” and “bad” for it, allow Nao to indicate how it’s feeling.

This originally made me think that Nao is just another basic robot, BUT found out that while the actions used to display each emotion are preprogrammed, Nao decides by itself which feeling to display, and when. (Robot agency!)

Hunching its shoulders when it’s sad and raising its arms for a hug when it’s happy, the robot really does emulate the physical expressions of a very young child. If frightened, Nao will only stop cowering in fear when soothed by gentle strokes on the head. Along with happiness, sadness and fright, Nao can also express anger, guilt, excitement and pride.

Beyond just being a novelty, Nao has several projected practical uses. The FEELIX team members in charge of creating Nao’s emotions believe that robots are absolutely going to act as human companions in the near future, and that responses from the robots will make it easier for humans to interact with them.

“If people can behave naturally around their robot companions, robots will be better-accepted as they become more common in our lives.”

In addition to being an ambassador for the ideal everyday companions of the future, one of the immediate aims of FEELIX’s project is to provide 24-hour companionship for young children and the elderly in hospitals and to provide support for their parents, carers, doctors and nurses. He would be capable of helping out with therapeutic aspects of their treatment, as well as providing companionship and helping their emotional well-being.

I don’t think we’re anywhere close to the point where robots will replace actual human attention, but they could be a great helper, when no one else is available. The public might not be ready for robot companions  with a mind of their own, but the technology is here, it’s consistently improving, and it can’t be ignored.

(All seriousness aside, I think my favorite thing about Nao is that he happens to be an awesome dancer, bringing a whole new meaning to ‘The Robot’.)
