ATOM-Bench: A Real-World Benchmark for Atomic Skills and Compositional Generalization in Manipulation Policies

arXiv:2606.16826v1 Announce Type: cross Abstract: Generalist manipulation policies are increasingly presented as foundation models for robotic control, but their real-world generalization remains difficult to diagnose. A policy may succeed on demonstrated tasks while still failing to execute fine-grained atomic skills or recombine learned skills in new task structures. We introduce \textbf{ATOM-Bench}, a real-world benchmark for evaluating both atomic skills and compositional generalization in manipulation policies. ATOM-Bench factorizes tabletop manipulation into motor atoms and instruction a

Why this matters
Why now

The increasing development of generalist manipulation policies and foundation models for robotic control necessitates robust, real-world benchmarks to diagnose their effectiveness and limitations.

Why it’s important

A robust benchmark for robotic skills will accelerate the development and deployment of more capable and reliable AI-driven robotic systems, impacting various industries.

What changes

The introduction of ATOM-Bench provides a standardized, real-world method for evaluating robotic manipulation generalisation, moving beyond simulated or narrow task successes.
