To develop a history-conditioned visuomotor diffusion policy that adapts to unknown changes in camera extrinsics, action scale, and control delays without test-time recalibration or weight updates.
Engineered SCE-DP, which encodes a short history of commands alongside visual and proprioceptive responses into a latent system context that conditions diffusion-based action denoising.
Incorporated auxiliary system-parameter regression and one-step response prediction to encourage the latent context to represent system dynamics.
Evaluated across five independently trained ManiSkill manipulation tasks spanning held-out in-range settings, withheld camera-delay combinations, and mild extrapolation domains against a domain-randomized Diffusion Policy baseline.
SCE-DP improved five-task macro-average success rates over the domain-randomized baseline by 14.5 percentage points on held-out configurations and 15.7 percentage points on withheld camera-delay compositions.
Across four shifted evaluation suites, SCE-DP achieved an average success rate of 64.3% compared to 48.9% for the baseline while preserving nominal performance.
Ablation controls (command-only, response-only, previous-action, and matched explicit parameters) confirmed performance gains stem specifically from joint command–response history modeling.
