Academic research into Task and Motion Planning (TAMP) has proceeded for well over a decade, producing key results in the analysis of, and algorithms for, TAMP scenarios. However, while certain aspects of TAMP research are currently reduced to practice, the overall inroads thus-far remain limited. This workshop aims to bring together academic and industry experts to discuss and reflect on the current state and direction of TAMP research and practice. Academic participants will offer the latest theoretical results and challenges in TAMP, while industry participants will present both successful applications and pragmatic challenges to TAMP adoption. Particularly, we aim to identify and discuss unsolved scientific challenges, and necessary systems developments, to broaden the impact of TAMP research. We hope that this workshop will stimulate insightful discussions and prioritization of efforts in TAMP research to address key practical needs.
This proposed workshop is supported by IEEE RAS Technical Committee on Algorithms for Planning and Control of Robot Motion as confirmed by the Technical Committee co-chairs Tsz-Chiu Au, Aleksandra Faust, Vadim Indelman, Marco Morales, Florian T. Pokorny, Hyejeong Ryu, and Sarah Tang.
This workshop is intended for researchers from academia, industry and government working in AI planning, motion planning, and controls who are interested in improving the autonomy of robots for complex, real-world tasks such as mobile manipulation.
The two main target audiences for the workshop are: (1) members actively researching new methods, future trends and open questions in task and motion planning (2) people who are interested in learning about the current state-of-the-art in order to incorporate these methods into their own projects. We strongly encourage the participation of graduate students.
This workshop follows the previous workshops on varying aspects of Task and Motion Planning in 2016-2020 from the same organizers. Past workshops received excellent participation with approximately 50 attendees, 10 presented posters, and engaging group discussions. During the previous workshops, numerous questions were raised regarding handling uncertainty and operating in real-world environments. This workshop aims to address these needs with specific focus on robust TAMP in practice.
This workshop continues a series of TAMP workshops:

Title: Large Language Models for Solving Long-Horizon Manipulation Problems
Abstract: My long-term research goal is enable real robots to manipulate any kind of object such that they can perform many different tasks in a wide variety of application scenarios such as in our homes, in hospitals, warehouses, or factories. Many of these tasks will require long-horizon reasoning and sequencing of skills to achieve a goal state. In this talk, I will present our work on enabling long-horizon reasoning on real robots for a variety of different long-horizon tasks that can be solved by sequencing a large variety of composable skill primitives. I will specifically focus on the different ways Large Language Models (LLMs) can help with solving these long-horizon tasks. The first part of my talk will be on TidyBot, a robot for personalised household clean-up. One of the key challenges in robotic household cleanup is deciding where each item goes. People's preferences can vary greatly depending on personal taste or cultural background. One person might want shirts in the drawer, another might want them on the shelf. How can we infer these user preferences from only a handful of examples in a generalizable way? Our key insight: Summarization with LLMs is an effective way to achieve generalization in robotics. Given the generalised rules, I will then show how TidyBot then solves the long-horizon task of cleaning up a home. In the second part of my talk, I will focus on more complex long-horizon manipulation tasks that exhibit geometric dependencies between different skills in a sequence. In these tasks, the way a robot performs a certain skill will determine whether a follow-up skill in the sequence can be executed at all. I will present an approach called text2motion that utilises LLMs for task planning without the need for defining complex symbolic domains. And I will show how we can verify whether the plan that the LLM came up with is actually feasible. The basis for this verification is a library of learned skills and an approach for sequencing these skills to resolve geometric dependencies prevalent in long-horizon tasks.
Bio: Jeannette Bohg a Professor for Robotics at Stanford University and directs the Interactive Perception and Robot Learning Lab. Her research generally explores two questions: What are the underlying principles of robust sensorimotor coordination in humans, and how we can implement these principles on robots? Research on this topic lies at the intersection of Robotics, Machine Learning and Computer Vision, and her lab focuses specifically on Robotic Grasping and Manipulation.
Bio:Georgia Chalvatzaki is an Assistant Professor at TU Darmstadt from February 2022. Before that, she was an Independednt Research Group Leader from March 2021, after getting the renowned Emmy Noether Programme (ENP) fund of the German Research Foundation (DFG). This project was awarded within the ENP Artificial Intelligence call of the DFG – only 9 proposals out of 91 proposals were selected for funding. It enables outstanding young scientists to qualify for a university professorship by independently leading a junior research group over six years.
In her research group iROSA, Dr. Chalvatzaki and her new team will research the topic of "Robot Learning of Mobile Manipulation for Assistive Robotics". Dr. Chalvatzaki proposes new methods at the intersection of machine learning and classical robotics, taking one step further the research for embodied AI robotic assistants. The research in iROSA proposes novel methods for combined planning and learning for enabling mobile manipulator robots to solve complex tasks in house-like environments, with the human-in-the-loop of the interaction process.
From October 2019, she was a Postodoctoral researcher at the Intelligent Autonous Systems group, advised by Jan Peters. Dr. Chalvatzaki completed her Ph.D. studies in 2019 at the Intelligent Robotics and Automation Lab at the Electrical and Computer Engineering School of the National Technical University of Athens, Greece, with her thesis "Human-Centered Modeling for Assistive Robotics: Stochastic Estimation and Robot Learning in Decision Making." During her career, she has worked on eight research projects, and she has published more than 30 papers, most of which in top-tier robotics and machine learning venues, e.g., ICRA, IROS, RA-L.
