What is Diffusion Policy?
Diffusion Policy generates robot actions with a diffusion model — the technique that made visuomotor imitation learning finally work reliably.
Why people choose Diffusion Policy
- State-of-the-art results on manipulation
- Reference implementation from the original paper
- Widely reused as a baseline
