Emotional Robotics

Daniel Bazo/Richard Craig

It is now well-accepted that for a robot to interact effectively with humans, it should manifest some form of believable behaviour establishing appropriate social expectations and regulating interaction.  We are working with the Bristol Robotics Laboraotory (BRL) to introduce a simplified robotic system capable of emotial (affective) human-robot communication without the complexity of full facial actuation, and to empirically assess human response to that robot for social interaction.  In addressing these two issues, we provide a basis for the larger goal of developing a mechanically simple platform for deeper human-robot cooperation as well as a method to quantify, neurologically, human response to affective robots.  The scope encompasses: 1) the development of hybrid-face humanoid robot capable of emotive response, including pupil dilation, and 2) the testing of hybrid-face through mapping human response to the robot qualitatively (interview/feedback) and quantitatively (EEG ERPs) based on human-robot testing.  Principal contributions lie in modelling of emotion affect space and mapping neurological response to robot emotion.

Brain Activity Map;  The BERT2 robot made Neutral, Angry, Stern and Happy facial expressions at a human subject test group with concurrent brain activitry (EEG) recorded.  The color map shows the parts of the brain that were most active when the person viewed the robot emotion.  The spatial EEG topography of evoked negative N170 response to robot facial expressions demonstrates similar brain activity to that of recognizing the same human facial expressions


The Biomechatronics Laboratory is collaboraiton with Emotix on the companion social robot Miko to commercialize this work.  Miko has been released to the public in India, and will be availalbe soon internationally.  See http://www.emotix.in/#2 for more information on this exciting product
