The paper discusses how robotic embodiment—sensing, kinematics, dynamics, geometry, actuation, and control—varies across robots and over time, and argues that general embodied intelligence must learn across these differences. It critiques current methods that engineer correspondences for short‑term gains, proposing instead that learning should discover representations that enable transfer across a broader range of embodiments as experience accumulates. The authors advocate for embodiment diversity as a scaling axis, broad learned priors as a complementary ingredient, and evaluations that better characterize embodiment gaps and transfer performance, linking practical cross‑embodiment learning to the scientific pursuit of physical intelligence that adapts with its embodiments.
Recent progress in large-scale imitation learning for robot manipulation has been driven by leveraging datasets across a wide range of robot embodiments. However, achieving significant cross-embodiment transfer is often still challenging.
The paper discusses the "embodiment gap" in robot foundation models, highlighting that while models can generalize across tasks, additional work is often needed to deploy them on specific robot bodies. It surveys what components can be reused across different robot embodiments and what must be implemented anew, mapping existing methods along axes of shared structure and adaptation stage. The authors propose a reporting framework to better assess adaptation efforts and identify remaining challenges for cross-embodiment learning.

Artificial general intelligence ultimately requires agents that can reason and act in the physical world. Action models, vision-language-action policies, and world models have advanced this goal, while World Action Models (WAMs) are particularly promising because they connect candidate interventions with predicted consequences.

AtomEgo investigates how to integrate large-scale egocentric human interaction data into embodied foundation model pre‑training. The study uses a curated 2,659‑hour corpus and a scalable data pipeline to evaluate three co‑training paradigms across vision‑language‑action and world‑action architectures. Results show that the benefit of egocentric data depends on both its scale and the quality of alignment with robotic embodiment, offering practical guidance for scalable ego‑robot pre‑training.
