A Soft Robotic Cover with Dual Thermal Display and Sensing Capabilities

We propose a new robotic cover prototype that achieves thermal display while also being soft. We focus on the thermal cue because previous human studies have identified it as part of the touch pleasantness. The robotic cover surface can be regulated to the desired temperature by circulating water through a thermally conductive pipe embedded in the cover, of which temperature is controlled. Besides, an observer for estimating heat from human contact is implemented; it can detect human interaction while displaying the desired temperature without temperature sensing on the surface directly. We assessed the validity of the prototype in experiments of temperature control and contact detection by human hand

Sensorimotor Oscillations During a Reciprocal Touch Paradigm With a Human or Robot Partner

Robots provide an opportunity to extend research on the cognitive, perceptual, and neural processes involved in social interaction. This study examined how sensorimotor oscillatory electroencephalogram (EEG) activity can be influenced by the perceived nature of a task partner – human or robot – during a novel “reciprocal touch” paradigm. Twenty adult participants viewed a demonstration of a robot that could “feel” tactile stimulation through a haptic sensor on its hand and “see” changes in light through a photoreceptor at the level of the eyes; the robot responded to touch or changes in light by moving a contralateral digit. During EEG collection, participants engaged in a joint task that involved sending tactile stimulation to a partner (robot or human) and receiving tactile stimulation back. Tactile stimulation sent by the participant was initiated by a button press and was delivered 1500 ms later via an inflatable membrane on the hand of the human or on the haptic sensor of the robot partner. Stimulation to the participant’s finger (from the partner) was sent on a fixed schedule, regardless of partner type. We analyzed activity of the sensorimotor mu rhythm during anticipation of tactile stimulation to the right hand, comparing mu activity at central electrode sites when participants believed that tactile stimulation was initiated by a robot or a human, and to trials in which “nobody” received stimulation. There was a significant difference in contralateral mu rhythm activity between anticipating stimulation from a human partner and the “nobody” condition. This effect was less pronounced for anticipation of stimulation from the robot partner. Analyses also examined beta rhythm responses to the execution of the button press, comparing oscillatory activity when participants sent tactile stimulation to the robot or the human partner. The extent of beta rebound at frontocentral electrode sites following the button press differed between conditions, with a significantly larger increase in beta power when participants sent tactile stimulation to a robot partner compared to the human partner. This increase in beta power may reflect greater predictably in event outcomes. This new paradigm and the novel findings advance the neuroscientific study of human–robot interaction

The power of affective touch within social robotics

There have been many leaps and bounds within social robotics, especially within human-robot interaction and how to make it a more meaningful relationship. This is traditionally accomplished through communicating via vision and sound. It has been shown that humans naturally seek interaction through touch yet the implications on emotions is unknown both in human-human interaction and social human-robot interaction. This thesis unpacks the social robotics community and the research undertaken to show a significant gap in the use of touch as a form of communication. The meaning behind touch will be investigated and what implication it has on emotions. A simplistic prototype was developed focusing on texture and breathing. This was used to carry out experiments to find out which combination of texture and movement felt natural. This proved to be a combination of synthetic fur and 14 breaths per minute. For human’s touch is said to be the most natural way of communicating emotions, this is the first step in achieving successful human-robot interaction in a more natural human-like way

“Hit the robot on the head with this mallet” – making a case for including more open questions in HRI research

Researchers continue to devise creative ways to explore the extent to which people perceive robots as social agents, as opposed to objects. One such approach involves asking participants to inflict ‘harm’ on a robot. Researchers are interested in the length of time between the experimenter issuing the instruction and the participant complying, and propose that relatively long periods of hesitation might reflect empathy for the robot, and perhaps even attribution of human-like qualities, such as agency and sentience. In a recent experiment, we adapted the so-called ‘hesitance to hit’ paradigm, in which participants were instructed to hit a humanoid robot on the head with a mallet. After standing up to do so (signaling intent to hit the robot), participants were stopped, and then took part in a semi-structured interview to probe their thoughts and feelings during the period of hesitation. Thematic analysis of the responses indicate that hesitation not only reflects perceived socialness, but also other factors including (but not limited to) concerns about cost, mallet disbelief, processing of the task instruction, and the influence of authority. The open-ended, free responses participants provided also offer rich insights into individual differences with regards to anthropomorphism, perceived power imbalances, and feelings of connection toward the robot. In addition to aiding understanding of this measurement technique and related topics regarding socialness attribution to robots, we argue that greater use of open questions can lead to exciting new research questions and interdisciplinary collaborations in the domain of social robotics

L’implantation de la robotique collaborative et la gestion des ressources humaines dans le secteur manufacturier : soutenir le changement et l’adoption

Ce mémoire de maîtrise explore l’implantation de la robotique collaborative en entreprise sous l’angle des pratiques de gestion et des facteurs humains. La visée initiale de ce projet de recherche visait préalablement à circonscrire l’apport que peut prendre la gestion des ressources humaines (GRH) lors de ce type d’implantation technologique, qui implique une collaboration humain-machine plus accrue qu’auparavant. Initialement, l’objectif était donc d’identifier les pratiques de GRH à mettre en place lors de l’implantation de robots collaboratifs. Cela dit, comme ce projet de recherche présente une démarche exploratoire semi-inductive, l’objectif de recherche a évolué vers plusieurs objectifs. Cette ouverture sur de nouveaux objectifs est subséquente aux résultats obtenus lors de la revue systématique de la littérature et de la collecte de données afin de dresser un portrait plus juste, adapté à l’état des connaissances et au terrain. Les objectifs poursuivis sont les suivants : 1) identifier les pratiques de GRH et d’autres pratiques organisationnelles en matière de gestion du changement facilitant l’implantation et l’adoption des robots collaboratifs 2) identifier les facteurs associés à l’humain, au robot et à l’environnement qui influencent l’implantation des robots collaboratifs, l’adoption et la collaboration entre l’opérateur et le robot

Human—Robot companionship: A mixed-methods investigation

In recent years, the arts have brought robots to life in spectacular fashion. In popular fiction we have been presented with machines that can run, leap, fight, and (perhaps most impressively of all) robots which can ascend stairs with absolutely no trouble at all. Amidst these chaotic and often dystopian scenes, we are exposed to moments of humour and lightness – robots can be seen engaging in conversation, cracking jokes, and comforting someone in their time of need. In these relatively mundane moments (as we smile, laugh, and cry) the impression emerges that the robot is something special to the person depicted. Rather than simply being a household appliance, it appears to be something more: a sort of… friend. Returning from the pages and screens of fiction to the real world, we find human society ever more fractured, and the loneliness epidemic at large. Unsurprisingly, given the engaging depictions in popular fiction, the idea of robots for companionship and social support is gaining traction and garnering increasing research attention. In care homes, robot animals can be found cooing and purring in the laps of individuals with dementia, while in schools, friendly humanoid robots may be seen teaching social skills to children with additional needs. What remains unknown, though, is the extent to which people will grow fond of such ‘social robots’ over time, and if so, whether their relationships with these machines might ever resemble (or indeed, replace) those with other humans. Is a ‘robot friend’ the stuff of science-fiction, or could it someday soon become sciencereality? In this thesis, this question is explored from a range of perspectives using a variety of methods spanning lab-based experiments, online surveys, and focus groups. This thesis begins with an introduction to social robots, and an exploration of the background regarding the nature and importance of human social relationships. After introducing relevant theories, I highlight gaps in our understanding of human—robot companionship that I seek to explore through this thesis (Chapter 1). In the subsequent chapters, I present four empirical pieces of work, each offering a unique perspective on the subject. Specifically, in Chapter 2, I report results from a lab-based experiment in which a robot’s lights (located within its shoulders) were programmed to illuminate in a synchronous or asynchronous manner relative to a participant’s heart rate. I aimed to determine whether such a synchrony manipulation might increase prosocial behaviours and improve attitudes towards a social robot - based on prior work showing that experimentally-induced movement synchrony can improve rapport between people, and increase their liking of social robots (Hove & Risen, 2009; Lehmann et al., 2015, Mogan, Fischer & Bulbulia, 2017). Despite demonstrating no positive effect of the light manipulation, this study raises important questions regarding the complexities of defining and measuring attachment to a robot. In Chapter 3, I delve deeper into the qualitative data collected in Chapter 2 to build a more complete appreciation of the value of open questions – particularly in terms of method validation and understanding participants’ internal experiences. After this chapter, I shift perspective from a focus on humanoid robots (and manipulations based on human social behaviours), to human relationships with non-human companion animals. This shift was motivated by my desire to explore how non-human agents form deep and enduring social bonds with humans – as opposed to basing the thesis on human interpersonal relationships alone. Due to the success of dogs as companions, I conducted a study in which dog owners were asked to identify behaviours that they perceived as important to the bond with their dog (Chapter 4). Seven key themes emerged from this research, indicating the importance of attunement, communication, consistency and predictability, physical affection, positivity and enthusiasm, proximity, and shared activities. In the following chapter, I implement a selection of ‘desirable’ dog behaviours within an animal-inspired robot (Chapter 5). By showing the behaviours to members of the general public, and conducting focus groups, I gained deeper insights into the polarising nature of robot animals – not only in terms of how their behaviours are perceived, but also in terms of the roles people think robots should (and should not) hold. In addition to these themes, this final empirical chapter discusses insights regarding the high expectations people place upon robots, as well as public concerns around overdependence on robots, and privacy. By releasing these chapters to the HRI community (through publications or preprints) we sparked conversations within the HRI community – not only about the ethics of robot abuse studies, but also the potential value of qualitative approaches within the field. Our team was commended for publishing qualitative research, in a field heavily dominated by quantitative methods, and we have since been working to continue the conversations around the value of qualitative approaches. Specifically, we hosted the “Enriching HRI Research with Qualitative Methods” workshop at the International Journal on Social Robotics (2020) and launched a “Qualitative Research in HRI/HCI Discussion Group” online - allowing HRI researchers to discuss their work, and share relevant resources (e.g., events and publications). This thesis concludes by detailing work to be done moving forwards, to enhance our understanding of human—robot social relationships, and a broader discussion of our possible future with social robots (Chapter 6). Pulling from various disciplines (including psychology, cognitive science, human—robot interaction (HRI) Studies, robot ethics, and philosophy), this section concludes with consideration of potential consequences of companion technologies – not only for the individual, but perhaps for society as a whole, as we continue to grapple with questions concerning how much of science fiction we wish to welcome into our daily lives
