FASA adjusts a diffusion policy’s denoising budget at runtime using visual and robot-state feedback. Its range adaptor expands or contracts allowed sampling steps, while a motion measure selects a step within that range. On three ManiSkill3 tasks, mean success rose from 70.28% to 76.39%, with a 1.45× average action-generation speedup over Diffusion Policy. These are simulation results, not real-robot validation.
