Safe Explicable Robot Planning
Human expectations stem from their knowledge of the others and the world.
Where human-robot interaction is concerned, such knowledge about the robot may
be inconsistent with the ground truth, resulting in the robot not meeting its
expectations. Explicable planning was previously introduced as a novel planning
approach to reconciling human expectations and the optimal robot behavior for
more interpretable robot decision-making. One critical issue that remains
unaddressed is safety during explicable decision-making which can lead to
explicable behaviors that are unsafe. We propose Safe Explicable Planning
(SEP), which extends explicable planning to support the specification of a
safety bound. The objective of SEP is to find a policy that generates a
behavior close to human expectations while satisfying the safety constraints
introduced by the bound, which is a special case of multi-objective
optimization where the solution to SEP lies on the Pareto frontier. Under such
a formulation, we propose a novel and efficient method that returns the safe
explicable policy and an approximate solution. In addition, we provide
theoretical proof for the optimality of the exact solution under the
designer-specified bound. Our evaluation results confirm the applicability and
efficacy of our method for safe explicable planning
Introduction to the special issue on âdesigning the robot body: Critical perspectives on affective embodied interactionâ
Designing and evaluating the affectivity of the robot body has become a frontier topic in Human-Robot Interaction (HRI), with previous studies emphasizing the importance of robot embodiment for human-robot communication. In particular, there is growing interest in how the tactile, haptic materiality of the robot influences and mediates usersâ affective and emotional states. Indeed, the sheer physicality of robotic systems is a crucial factor in the morphology of the robotic platform, and therefore in the robot's appearance to the user. How do the tactile properties of materials subtly influence user interaction? Why do certain morphologies prompt more empathetic interactions than others? How is nonverbal communication affected through the coordination of movements of the torso, head, and appendages to provide more naturalistic-seeming interaction? What is the role of nonverbal communication in the production of artificial empathy? And how do such factors encourage trust and foster confidence for nonexpert users to interact in the first place? This recognition of machinic corporeality has been of practical interest to designers and engineers working across a range of robot forms and functions.
The objective of this special issue is to further this discussion, to consider theoretical, ethical, empirical, and methodological questions related to the design of robotic bodies in the context of affective HRI, and thus foster cross currents among engineering, design, social science, and artistic communities. It originally emerged as a set of conceptual and practical questions from a workshop at the 2020 ACM/IEEE International Conference on Human-Robot Interaction (HRIâ20) in Cambridge, UK, co-organized by two of the editors [3]. The workshop, like so many other events, was canceled because of the restrictions of the COVID-19 pandemic. Consequently, we tried to pursue a longer-term exchange of engineering, design, and conceptual considerations through the publication of this special issue. Building out from the more practically minded exchanges of an in-person workshop, here was an opportunity to invite more wide-ranging contributions to consider questions related to the design of robotic bodies in the context of affective HRI. The issue could thus explore topics bridging embodiment and affect, including touch, materials, and physical form from the points of view of artists, designers, engineers, and social scientists alike
Choreographic and Somatic Approaches for the Development of Expressive Robotic Systems
As robotic systems are moved out of factory work cells into human-facing
environments questions of choreography become central to their design,
placement, and application. With a human viewer or counterpart present, a
system will automatically be interpreted within context, style of movement, and
form factor by human beings as animate elements of their environment. The
interpretation by this human counterpart is critical to the success of the
system's integration: knobs on the system need to make sense to a human
counterpart; an artificial agent should have a way of notifying a human
counterpart of a change in system state, possibly through motion profiles; and
the motion of a human counterpart may have important contextual clues for task
completion. Thus, professional choreographers, dance practitioners, and
movement analysts are critical to research in robotics. They have design
methods for movement that align with human audience perception, can identify
simplified features of movement for human-robot interaction goals, and have
detailed knowledge of the capacity of human movement. This article provides
approaches employed by one research lab, specific impacts on technical and
artistic projects within, and principles that may guide future such work. The
background section reports on choreography, somatic perspectives,
improvisation, the Laban/Bartenieff Movement System, and robotics. From this
context methods including embodied exercises, writing prompts, and community
building activities have been developed to facilitate interdisciplinary
research. The results of this work is presented as an overview of a smattering
of projects in areas like high-level motion planning, software development for
rapid prototyping of movement, artistic output, and user studies that help
understand how people interpret movement. Finally, guiding principles for other
groups to adopt are posited.Comment: Under review at MDPI Arts Special Issue "The Machine as Artist (for

Embodied Robot Models for Interdisciplinary Emotion Research
Due to their complex nature, emotions cannot be properly understood from the perspective of a single discipline. In this paper, I discuss how the use of robots as models is beneficial for interdisciplinary emotion research. Addressing this issue through the lens of my own research, I focus on a critical analysis of embodied robots models of different aspects of emotion, relate them to theories in psychology and neuroscience, and provide representative examples. I discuss concrete ways in which embodied robot models can be used to carry out interdisciplinary emotion research, assessing their contributions: as hypothetical models, and as operational models of specific emotional phenomena, of general emotion principles, and of specific emotion ``dimensions''. I conclude by discussing the advantages of using embodied robot models over other models.Peer reviewe
Special issue on smart interactions in cyber-physical systems: Humans, agents, robots, machines, and sensors
In recent years, there has been increasing interaction between humans and nonâhuman systems as we move further beyond the industrial age, the information age, and as we move into the fourthâgeneration society. The ability to distinguish between human and nonâhuman capabilities has become more difficult to discern. Given this, it is common that cyberâphysical systems (CPSs) are rapidly integrated with human functionality, and humans have become increasingly dependent on CPSs to perform their daily routines.The constant indicators of a future where human and nonâhuman CPSs relationships consistently interact and where they allow each other to navigate through a set of nonâtrivial goals is an interesting and rich area of research, discovery, and practical work area. The evidence of con- vergence has rapidly gained clarity, demonstrating that we can use complex combinations of sensors, artificial intelli- gence, and data to augment human life and knowledge. To expand the knowledge in this area, we should explain how to model, design, validate, implement, and experiment with these complex systems of interaction, communication, and networking, which will be developed and explored in this special issue. This special issue will include ideas of the future that are relevant for understanding, discerning, and developing the relationship between humans and nonâ human CPSs as well as the practical nature of systems that facilitate the integration between humans, agents, robots, machines, and sensors (HARMS).Fil: Kim, Donghan.
