Pixel Motion Diffusion is What We Need for Robot Control
This addresses scalable and robust robot learning for manipulation tasks, though it appears incremental as it builds on existing diffusion methods.
The authors tackled robot control by proposing DAWN, a diffusion-based framework for language-conditioned manipulation, which achieved state-of-the-art results on the CALVIN benchmark and demonstrated reliable real-world transfer with minimal finetuning.
We present DAWN (Diffusion is All We Need for robot control), a unified diffusion-based framework for language-conditioned robotic manipulation that bridges high-level motion intent and low-level robot action via structured pixel motion representation. In DAWN, both the high-level and low-level controllers are modeled as diffusion processes, yielding a fully trainable, end-to-end system with interpretable intermediate motion abstractions. DAWN achieves state-of-the-art results on the challenging CALVIN benchmark, demonstrating strong multi-task performance, and further validates its effectiveness on MetaWorld. Despite the substantial domain gap between simulation and reality and limited real-world data, we demonstrate reliable real-world transfer with only minimal finetuning, illustrating the practical viability of diffusion-based motion abstractions for robotic control. Our results show the effectiveness of combining diffusion modeling with motion-centric representations as a strong baseline for scalable and robust robot learning.
