The Feelix Growing project aims to design and build a series of robots that can interact with humans on an emotional level, and actually adapt their behavior in response to emotional cues from their human counterparts.
The official goal of the project is to conduct "interdisciplinary investigation of socially situated development ... as a key paradigm towards achieving robots that interact with humans in their everyday environments in a rich, flexible, autonomous, and user-centered way." To achieve this, the 2.3 million-Euro effort has assembled more than two dozen roboticists, developmental psychologists and neuroscientists from six nations.
The robots used in the project are simple designs, including some "off-the-shelf" models. The complexity lies in the software, which will construct artificial neural networks to pick up on human emotions exhibited via facial expressions, voice intonation, gestures and other behaviors.
The leader of the European Commission-funded project, Dr. Lola Canamero is a senior lecturer in the School of Computer Science at the University of Hertfordshire, England. She also serves as the principal investigator and coordinator of the university's Adaptive Systems Research Group, which focuses on researching socially intelligent agents, emotion modeling, developmental robotics, human-robot and human-computer interaction, embodied artificial intelligence and robotics, sensor evolution and artificial life.
In a recent interview with BBC, Canamero said the robots will be designed to detect basic human emotional states such as anger, happiness, and loneliness. Once the states are detected, the robots will be programmed to perform a support role, by seeking to soothe an angry human, or cheer up a lonely or depressed one.
One of the first fruits of the Feelix Growing effort has been the production of a robot capable of "imprinting" behavior. The behavior is similar to the way many baby animals develop an instinctual attachment to the first adult they see at the time of birth, usually the mother. The imprinting robot prototype learns to recognize a particular human and follow that individual around, gradually adapting to the human's actions and emotional state, then interacting accordingly, Canamero said.
At the conclusion of the project, the scientists intend to build two robots that will combine aspects of the research being conducted at each of the eight partner sites scattered around Europe.
