Contemporary research in human-robot interaction (HRI) predominantly focuses on the user's experience while controlling a robot. However, with the increased deployment of artificial intelligence (AI) techniques, robots are quickly becoming more autonomous in both academic and industrial experimental settings. In addition to improving the user's interactive experience with AI-operated robots through personalization, dialogue, emotions, and dynamic behavior, there is also a growing need to consider the safety of the interaction. AI may not account for the user's less likely responses, making it possible for an unaware user to be injured by the robot if they have a collision. Issues of trust and acceptance may also come into play if users cannot always understand the robot's thought process, creating a potential for emotional harm. We identify challenges that will need to be addressed in safe AI-HRI and provide an overview of approaches to consider for them, many stemming from the contemporary research.


AI for Human-Robot Interaction

AI Magazine

This article contains the reports of the AI for Human-Robot Interaction, Cognitive Assistance in Government and Public Sector Applications, Deceptive and Counter-Deceptive Machines, Self-Confidence in Autonomous Systems, and Sequential Decision Making for Intelligent Agents symposia, which were held November 12-14, 2015 in Arlington, Virginia. The titles of the six symposia were as follows: AI for Human-Robot Interaction, Cognitive Assistance in Government and Public Sector Applications, Deceptive and Counter-Deceptive Machines, Embedded Machine Learning, Self-Confidence in Autonomous Systems, and Sequential Decision Making for Intelligent Agents. This article contains the reports from five of the symposia. Human-robot interaction (HRI) is a broad community encompassing robotics, artificial intelligence (AI), human-computer interaction (HCI), psychology, and social science. In this meeting, we sought to bring together and strengthen the subset of the HRI community that is focused on the AI challenges inherent to HRI.


"Quis Custodiet Ipsos Custodes?", Artificial Intelligence and the Interactionist Stance

The lure of understanding biological intelligence has long occupied researchers. Success has always been measured in peer review, number of citations, or how influential some piece of work is in inspiring the next generation of re- searchers. What human-robot interaction (HRI) and artificial intelligence (AI) promises is a metric of believability that is not intrinsic to the values of the researcher or community of practice but to the utility and successful function of the robotic artifact within a larger society. This paper is a reflec- tion and response to the hypothesis that HRI is a pure, funda- mental art of artificial intelligence and the last great successor to a domain fraught with the trappings of an art that lost its way.


Modeling Human Temporal Uncertainty in Human-Agent Teams

arXiv.org Artificial Intelligence

Automated scheduling is potentially a very useful tool for facilitating efficient, intuitive interactions between a robot and a human teammate. However, a current gapin automated scheduling is that it is not well understood how to best represent the timing uncertainty that human teammates introduce. This paper attempts to address this gap by designing an online human-robot collaborative packaging game that we use to build a model of human timing uncertainty from a population of crowd-workers. We conclude that heavy-tailed distributions are the best models of human temporal uncertainty, with a Log-Normal distribution achieving the best fit to our experimental data. We discuss how these results along with our collaborative online game will inform and facilitate future explorations into scheduling for improved human-robot fluency.

Performing experimental research on robotic platforms involves numerous practical complications, while studying collaborative interactions and efficiently collecting data from humans benefit from real time response. Roboticists can circumvent some complications by using simulators like Gazebo to test algorithms and building games like the Mars Escape game to collect data. Making use of existing resources for simulation and game creation requires the development of assets and algorithms along with the recruitment and training of users. We have created a Minecraft mod called BurlapCraft which enables the use of the reinforcement learning and planning library BURLAP to model and solve different tasks within Minecraft. BurlapCraft makes AI-HRI development easier in three core ways: the underlying Minecraft environment makes the construction of experiments simple for the developer and so allows the rapid prototyping of experimental setup; BURLAP contributes a wide variety of extensible algorithms for learning and planning, allowing easy iteration and development of task models and algorithms; and the familiarity and ubiquity of Minecraft trivializes the recruitment and training of users. To validate BurlapCraft as a platform for AI development, we demonstrate the execution of A*, BFS, RMax, language understanding, and learning language groundings from user demonstrations in five Minecraft "dungeons."
