Are Discrete Emotions Useful in Human-Robot Interaction? : Feedback from Motion Capture Analysis
Lewis, Matthew; Cañamero, Lola (IEEE COMPUTER SOC, 2013)We have conducted a study analyzing motion capture data of bodily expressions of human emotions towards the goal of building a social expressive robot that interacts with and supports hospitalized children. Although modeling ... -
Arousal regulation and affective adaptation to human responsiveness by a robot that explores and learns a novel environment
Hiolle, Antoine; Lewis, Matthew; Cañamero, Lola (2014-05-14)In the context of our work in developmental robotics regarding robot-human caregiver interactions, in this paper we investigate how a "baby" robot that explores and learns novel environments can adapt its affective regulatory ... -
Does Expression of Grounded Affect in a Hexapod Robot Elicit More Prosocial Responses?
Hickton, Luke; Lewis, Matthew; Koay, Kheng; Cañamero, Lola (EPSRC UK-RAS Network, 2020-05-07)We consider how non-humanoid robots can communicate their affective state via bodily forms of communication, and the extent to which this can influence human response. We propose a simple model of grounded affect and kinesic ... -
An Embodied AI Approach to Individual Differences : Supporting Self-Efficacy in Diabetic Children with an Autonomous Robot
Lewis, Matthew; Oleari, Elettra; Pozzi, Clara; Cañamero, Lola (Springer Nature, 2015-10)In this paper we discuss how a motivationally autonomous robot, designed using the principles of embodied AI, provides a suitable approach to address individual differences of children interacting with a robot, without ... -
Epigenetic adaptation in action selection environments with temporal dynamics
Lones, John; Cañamero, Lola; Lewis, Matthew (MIT Press, 2013-09-02)To operate in dynamic environments robots must be able to adapt their behaviour to meet the challenges that these pose while being constrained by their physical and computational limitation. In this paper we continue our ... -
Expression of Grounded Affect: How Much Emotion Can Arousal Convey?
Hickton, Luke; Lewis, Matthew; Cañamero, Lola (Springer Nature, 2020-12-03)In this paper we consider how non-humanoid robots can communicate their affective state via bodily forms of communication (kinesics), and the extent to which this influences how humans respond to them. We propose a simple ... -
A flexible component-based robot control architecture for hormonal modulation of behaviour and affect
Hickton, Luke; Lewis, Matthew; Cañamero, Lola (Springer Nature, 2017-07-20)In this paper we present the foundations of an architecture that will support the wider context of our work, which is to explore the link between affect, perception and behaviour from an embodied perspective and assess ... -
From Sensorimotor Experiences to Cognitive Development: : How Does Experiential Diversity Influence the Development of an Epigenetic Robot?
Lones, John; Lewis, Matthew; Canamero, Lola (2016-08-26)Using an epigenetic model, in this paper we investigate the importance of sensorimotor experiences and environmental conditions in the emergence of more advanced cognitive abilities in an autonomous robot. We let the robot ... -
Hedonic Quality or Reward? A Study of Basic Pleasure in Homeostasis and Decision Making of a Motivated Autonomous Robot
Lewis, Matthew; Canamero, Lola (2016-10-12)We present a robot architecture and experiments to investigate some of the roles that pleasure plays in the decision making (action selection) process of an autonomous robot that must survive in its environment. We have ... -
A Hormone-Driven Epigenetic Mechanism for Adaptation in Autonomous Robots
Lones, John; Lewis, Matthew; Cañamero, Lola (2018-06-01)Different epigenetic mechanisms provide biological organisms with the ability to adjust their physiology and/or morphology and adapt to a wide range of challenges posed by their environments. In particular, one type of ... -
Making New "New AI" Friends : Designing a Social Robot for Diabetic Children from an Embodied AI Perspective
Canamero, Lola; Lewis, Matthew (2016-06-30)Robin is a cognitively and motivationally autonomous affective robot toddler with "robot diabetes" that we have developed to support perceived self-efficacy and emotional wellbeing in children with diabetes by providing ... -
Modelling the Social Buffering Hypothesis in an Artificial Life Environment
Khan, Imran; Lewis, Matthew; Cañamero, Lola (MIT Press, 2020-07-14)In social species, individuals who form social bonds have been found to live longer, healthier lives. One hypothesised reason for this effect is that social support, mediated by oxytocin, “buffers” responses to stress in ... -
A Robot Model of OC-Spectrum Disorders : Design Framework, Implementation and First Experiments
Lewis, Matthew; Canamero, Lola; Fineberg, Naomi (2019-06-19)Computational psychiatry is increasingly establishing itself as valuable discipline for understanding human mental disorders. However, robot models and their potential for investigating embodied and contextual aspects of ... -
A Robot Model of Stress-Induced Compulsive Behavior
Lewis, Matthew; Cañamero, Lola (Institute of Electrical and Electronics Engineers (IEEE), 2019-09-06)Stress is one of the potential mechanisms underlying compulsive behavior in obsessive-compulsive spectrum disorders. In this paper, we present a robot model and experiments investigating the interactions between internally- ... -
Robot Models of Mental Disorders
Lewis, Matthew; Cañamero, Lola (Institute of Electrical and Electronics Engineers (IEEE), 2018-02-01)Alongside technological tools to support wellbeing and treatment of mental disorders, models of these disorders can also be invaluable tools to understand, support and improve these conditions. Robots can provide ecologically ...
