Emotional robots!

Research aims to create robots with empathy; project envisions automatons that will learn from experience how to respond to emotions displayed by people around it…

Arobot with empathy sounds like the stuff of sci-fi movies, but with the aid of neural networks, European researchers associated with the ‘Feelix Growing project’ are developing robots in tune with human emotions.

The project involves itself with developing software that will lead to robots that can learn when a person is happy, sad or angry.

The learning part is achieved through the use of artificial neural networks, which are well-suited to the varied and changing inputs that ‘perceptive’ robots would be exposed to.

Using cameras and sensors, the simple robots being built by the researchers – using mostly off-the-shelf parts – can detect different parameters, such as a person’s facial expressions, voice, and proximity to determine emotional state.

The technology combines together research in robotics, adaptive systems, neuroscience, developmental and comparative psychology – and ethology, which is all about human behaviour.

ARE YOU FEELING OK?
Much like a human child, the robot learns from experience how to respond to emotions displayed by people around it.

“If someone shows fear or cries out in pain, the robot may learn to change its behaviour to appear less threatening, backing away if necessary,” said project coordinator Dr Lola Canamero. “If someone cries out in happiness, it may even detect the difference, and one day, finetune its responses to individuals. It’s mostly behavioural and contact feedback.”

The three-year project involves six countries and 25 specialists who are building demonstration robots as proof of concept.

One demo follows the researchers around like a young bear cub might its mother, learning from experience when to trail behind or stick close to her. A robot face is also in development which can express different ‘emotions’.

“The main idea is, by being more in tune with human emotions, giving the impression of empathy, the robots should be more readily accepted by the people they may one day serve,” Canamero said.

NOT EXACTLY I, ROBOT
Automatons that can adapt to people’s behaviours are needed if machines are to play a part in society, such as helping the sick, the elderly, people with autism or house-bound people, working as domestic helpers, or just for entertainment, according to Canamero.

The work is still well shy of an I Robot scenario with emotionally complex machines taking matters into their own hands, but the empathy empowering software being developed by Feelix Growing is a big step forward for robotics.

And gauging by the attention the project has garnered in leading international press, such as the BBC, Wired and Engadget, Feelix Growing is maturing very well. ICT RESULTS
