KinDER: A Physical Reasoning Benchmark for Robot Learning and Planning

Hugging Face Daily Papers Papers

Summary

KinDER is a new open-source benchmark for physical reasoning in robotics, featuring procedurally generated environments and baselines to evaluate kinematic and dynamic constraint challenges.

Robotic systems that interact with the physical world must reason about kinematic and dynamic constraints imposed by their own embodiment, their environment, and the task at hand. We introduce KinDER, a benchmark for Kinematic and Dynamic Embodied Reasoning that targets physical reasoning challenges arising in robot learning and planning. KinDER comprises 25 procedurally generated environments, a Gymnasium-compatible Python library with parameterized skills and demonstrations, and a standardized evaluation suite with 13 implemented baselines spanning task and motion planning, imitation learning, reinforcement learning, and foundation-model-based approaches. The environments are designed to isolate five core physical reasoning challenges: basic spatial relations, nonprehensile multi-object manipulation, tool use, combinatorial geometric constraints, and dynamic constraints, disentangled from perception, language understanding, and application-specific complexity. Empirical evaluation shows that existing methods struggle to solve many of the environments, indicating substantial gaps in current approaches to physical reasoning. We additionally include real-to-sim-to-real experiments on a mobile manipulator to assess the correspondence between simulation and real-world physical interaction. KinDER is fully open-sourced and intended to enable systematic comparison across diverse paradigms for advancing physical reasoning in robotics. Website and code: https://prpl-group.com/kinder-site/

Abstract

KinDER is a benchmark for physical reasoning in robotics that includes procedurally generated environments and baselines spanning multiple learning paradigms to address kinematic and dynamic constraint challenges.

Robotic systemsthat interact with the physical world must reason about kinematic anddynamic constraintsimposed by their own embodiment, their environment, and the task at hand. We introduce KinDER, a benchmark for Kinematic and DynamicEmbodied Reasoningthat targetsphysical reasoningchallenges arising in robot learning and planning. KinDER comprises 25 procedurally generated environments, a Gymnasium-compatible Python library with parameterized skills and demonstrations, and a standardized evaluation suite with 13 implemented baselines spanning task andmotion planning,imitation learning,reinforcement learning, and foundation-model-based approaches. The environments are designed to isolate five corephysical reasoningchallenges: basic spatial relations, nonprehensile multi-object manipulation, tool use, combinatorial geometric constraints, anddynamic constraints, disentangled from perception, language understanding, and application-specific complexity. Empirical evaluation shows that existing methods struggle to solve many of the environments, indicating substantial gaps in current approaches tophysical reasoning. We additionally includereal-to-sim-to-real experimentson a mobile manipulator to assess the correspondence between simulation and real-world physical interaction.
