Unified Task and Motion Planning using Object-centric Abstractions of Motion Constraints

no code implementations29 Dec 2023 Alejandro Agostini, Justus Piater

In task and motion planning (TAMP), the ambiguity and underdetermination of abstract descriptions used by task planning methods make it difficult to characterize physical constraints needed to successfully execute a task.

Long-Horizon Planning and Execution with Functional Object-Oriented Networks

no code implementations12 Jul 2022 David Paulius, Alejandro Agostini, Dongheui Lee

We demonstrate our entire approach on long-horizon tasks in CoppeliaSim and show how learned action contexts can be extended to never-before-seen scenarios.

A Road-map to Robot Task Execution with the Functional Object-Oriented Network

no code implementations1 Jun 2021 David Paulius, Alejandro Agostini, Yu Sun, Dongheui Lee

Following work on joint object-action representations, the functional object-oriented network (FOON) was introduced as a knowledge graph representation for robots.

Efficient State Abstraction using Object-centered Predicates for Manipulation Planning

no code implementations16 Jul 2020 Alejandro Agostini, Dongheui Lee

To tackle these limitations we propose an object-centered representation that permits characterizing a much wider set of possible changes in configuration spaces than the traditional observer perspective counterpart.
