The Workshop on Longitudinal Human-Robot Teaming is a half-day workshop being held on March 5th, 2018 in conjunction with HRI 2018 in Chicago, Illinois.

As robots that share working and living environments with humans proliferate, human-robot teamwork is becoming increasingly relevant to an ever-expanding array of domains. Though continuing research strives to make robots more independent during times when unsupervised activity is desirable or necessary (i.e., autonomy), a complementary effort to make them capable of sophisticated interdependent joint activity with people and other robots is also required (i.e., teamwork). This includes not only fluid orchestration of task hand-offs among different people and robots, but also combined participation on shared tasks requiring continuous and close interaction (i.e., co-activity). Joint activity requires effective cooperation, coordination and communication among human and robot participants. For humans, the social qualities required for joint activity come naturally. For robots, they need to be "designed-in" deeply from the beginning in order for them to become effective team-players. It is not enough to paint on a a thin veneer of a pretty interface after the fact.

Importantly, teamwork does happen in just one moment, but extends and develops over time. Long-term joint activity is bound to face changes in the environment, possibly changes in the (structure of) the team and/or in the way that tasks are performed and in the expectations that team members have of each other and their teaming. As a team faces different situations it accumulates experience and this allows it to grow.

This workshop aims to explore and discuss theories, algorithms, tools, computational models and design methodologies that enable effective and safe longitudinal human-robot teaming. We place particular emphasis on types of human-robot teamwork that develop over time, such as ways in which robots/systems can adapt to better accommodate the requirements of a task that is shared with humans, in particular in real, unstructured and uncontrolled environments -- i.e. those in which systems need to deal with uncertainty. This workshop welcomes submissions investigating a wide variety of research topics, including:

• Dealing with changes over time (e.g. task and team structures, goals, etc)
• Dealing with uncertainty about the environments (both spatial and social)
• Learning and adaptation over time to become an effective team-member
• Joint activity planning under uncertainty
• Designing for long-term interdependence within human-robot teams
• Understanding, modeling, and shaping long-term team dynamics in mixed human-robot teams
• Collaborator action and sustainable preference modeling
• Generating verbal and non-verbal acts for management and coordination of team activities developing over time
• Leveraging human-robot interaction to request assistance or to recover from failure modes

This workshop organized in part by the TRADR Project.
