About

Over the past decade, decision-making agents have been increasingly deployed in industrial settings, consumer products, healthcare, education, and entertainment. The development of drone delivery services, virtual assistants, and autonomous vehicles have highlighted numerous challenges surrounding the operation of autonomous systems in unstructured environments. This includes mechanisms to support autonomous operations over extended periods of time, techniques that facilitate the use of human assistance in learning and decision-making, learning to reduce the reliance on humans over time, addressing the practical scalability of existing methods, relaxing unrealistic assumptions, and alleviating safety concerns about deploying these systems.

This symposium aims to identify the challenges and bridge the gaps between theoretical frameworks for planning and learning in autonomous agents and the requirements imposed by deployment in the real world. Our goal is to help identify research avenues that can move the AI community beyond highly theoretical results for simple domains or highly engineered one-shot solutions for realistic applications. We seek papers that find a common middle ground between theory and applications, and analyze the lessons learned from these efforts, particularly with respect to long-term autonomy.

The symposium combines invited talks, presentations, and discussions from both an AI and a robotics perspective.

Topics

Topics of interest include, but are not limited to, the following:

  • Decision-making representations, models, and algorithms for the real world
  • Hierarchical and multi-objective solutions for scalable planning and learning
  • Efficient integrations of task and motion planning
  • Integrating planning, reasoning, and learning for long-term deployments
  • Safety in real-world decision-making and learning
  • Scalable multiagent and human-in-the-loop techniques
  • Proactively incorporating human feedback in decision-making
  • Leveraging the complimentary capabilities of humans and robots in real-world tasks
  • Evaluation metrics for long-term autonomy
  • Case studies and descriptions of deployed autonomous systems
  • Lessons learned from deployed applications of autonomous systems

Invited Talks

Nick Hawes Speaker: Dr. Nick Hawes, Associate Professor of Robotics at the University of Oxford
Title: Learning From Four Years of Mobile Autonomy
Abstract: In this talk I will look back over four years of long-term deployments of autonomous mobile robots in everyday environments. From this I will present examples of the kinds of things that mobile robots can learn over long autonomous operations in such environments, including navigation information, human activities, object models, and mission schedules. Following this I will explore the issues (software, hardware, and social) that impacted upon the autonomy of our deployed robots, and look at what we can learn from these experiences as both AI practitioners and as engineers deploying robots in real environments.


Tom Wagner Speaker: Dr. Tom Wagner, CEO of Berkshire Grey, Former CTO of iRobot
Title: Challenges and Opportunities for Long-Term Autonomy in Deployed Systems
Abstract: Artificial Intelligence applied to both virtual agents and physical agents (robotics) is transforming how work is performed in cyberspace and in the physical world. Joining technology often considered “research” with real-world deployed systems opens the door to questions about what can and should happen with such systems over time. Should such systems change over time? Should they not? Are there situations where the work task cannot be performed unless the systems adapt and change as they operate? What are the expectations and desires of the stakeholders in these circumstances and what are the implications of embedding reasoning, learning, planning, etc., subsystems in commercial applications? In this talk we will walk through example applications based on experiences with industrial systems, consumer systems, and military systems. Via these examples and their associated AI elements, together we will explore issues such as scoping, challenges, opportunities, and expectations which may help further application of our technologies to such problems.


Peter Wurman Speaker: Dr. Peter Wurman, VP of Engineering at Cogitai, Former Co-founder of Kiva Systems
Title: How Kiva Robots Disrupted Warehousing
Abstract: Kiva Systems introduced swarms of agile robots into an industry dominated by stationary conveyor systems. The path from concept through successful startup and eventual acquisition involved challenges on all fronts. In this talk I’ll explain the business problem that motivated the innovation, Kiva technology and the benefits it brought to customers, and the future of applications of robotics in warehouses.

Paper Presentations

Papers will be presented either in a long format (25 minute) or short format (15 minute) based on paper length and relevance to long-term autonomy (LTA).

To focus the discussion on the symposium's topic, all presentations should reserve 3-5 minutes at the end of their talk to relate their paper directly to long-term autonomy. They can provide their brief perspectives on the topic if appropriate as well.

Thus, long presentations should be 15 minutes of content, 5 minutes of relations to LTA, and 5 minutes of Q&A. Short presentations should be 10 minutes of content, 3 minutes of relations to LTA, and 2 minutes of Q&A.

Panel Discussion

The panel discussion will conclude the symposium with reflections and perspectives from the invite talks and papers on the state of long-term autonomy overall.

Moderator: Joydeep Biswas, University of Massachusetts Amherst

The panel members include: TBD.
