Robots that develop emotions in interaction with humans August 12, 2010
The first prototype robots capable of developing emotions as they interact with their human caregivers and expressing a whole range of emotions have been finalised by researchers.
The first prototype robots capable of developing emotions as they interact with their human caregivers and expressing a whole range of emotions have been finalised by researchers.
Led by Dr. Lola Cañamero at the University of Hertfordshire, and in collaboration with a consortium of universities and robotic companies across Europe, these robots differ from others in the way that they form attachments, interact and express emotion through bodily expression.
Developed as part of the interdisciplinary project FEELIX GROWING (Feel, Interact, eXpress: a Global approach to development with Interdisciplinary Grounding), funded by the European Commission and coordinated by Dr. Cañamero, the robots have been developed so that they learn to interact with and respond to humans in a similar way as children learn to do it, and use the same types of expressive and behavioural cues that babies use to learn to interact socially and emotionally with others.
The robots have been created through modelling the early attachment process that human and chimpanzee infants undergo with their caregivers when they develop a preference for a primary caregiver.
They are programmed to learn to adapt to the actions and mood of their human caregivers, and to become particularly attached to an individual who interacts with the robot in a way that is particularly suited to its personality profile and learning needs. The more they interact, and are given the appropriate feedback and level of engagement from the human caregiver, the stronger the bond developed and the amount learned.
The robots are capable of expressing anger, fear, sadness, happiness, excitement and pride and will demonstrate very visible distress if the caregiver fails to provide them comfort when confronted by a stressful situation that they cannot cope with or to interact with them when they need it.
"This behaviour is modelled on what a young child does," said Dr Cañamero. “This is also very similar to the way chimpanzees and other non-human primates develop affective bonds with their caregivers.”
This is the first time that early attachment models of human and non-human primates have been used to program robots that develop emotions in interaction with humans.
“We are working on non-verbal cues and the emotions are revealed through physical postures, gestures and movements of the body rather than facial or verbal expression,” Dr Cañamero added.
From Fox SlewsOctavia, on display at the Office of Naval Research for Fleet Week in New York until June 1, is an autonamous robot designed to interact with humans.
She has a very expressive face, and hands and fingers, which she can use to express herself non-verbally.
“So Octavia can respond to humans in human ways, such as raising an eyebrow to reveal skepticism or tilting her head coyly to suggest that she doesn’t understand something. More importantly, she does this autonomously, using a system of sensors and cameras to follow what’s going on around her and then thinking and reacting to her environment independently.”
FROM CONVEYING NEWS The US military has expressed a keen interest in funding a so-called biomass robot that is in development in the states.
Coined the EATR (Energetically Autonomous Tactical Robot), product designers at Robotic Technology have developed a biomass guzzling machine that is capable of self-fuelling in order to operate.
According to the firm, the aim of EATR project, which first came to fruition in 2003, is to "develop and demonstrate an autonomous robotic platform able to perform long-range, long-endurance missions without the need for manual or conventional re-fuelling".
The robot is reportedly capable of locating its own fuel sources, from which it can ingest and extract energy from biomass found in the natural environment.
It is hoped the technology could be used to assist in the operation of both manned and unmanned vehicles, particularly in the field of battle.
With Britain bidding to place itself as a global leader in renewable energy technologies, our counterparts in the States may soon be called on British manufacturers to create the prototype robot, or similar bio-fuelled machines.
