UniConFlow is a unified constrained flow‑matching framework that generates robot trajectories while systematically handling both equality and inequality constraints such as collision avoidance, actuation limits, and dynamic consistency. It introduces a prescribed‑time zeroing function to shape a time‑varying guidance field during inference, and employs a violation‑segment extraction protocol and trajectory compression to address computational challenges in long‑horizon, high‑dimensional planning. Experiments on a double inverted pendulum, a real‑to‑sim car racing task, and a sim‑to‑real manipulation task show that UniConFlow outperforms state‑of‑the‑art generative planners and conventional optimization baselines on certified motion planning metrics like safety, kinodynamic consistency, and action feasibility.

The paper introduces Coupled Guidance, a flow‑matching‑specific guidance mechanism that addresses instability issues arising from directly adapting diffusion guidance methods. By leveraging the coupling structure inherent to flow‑matching training, the authors provide a theoretical analysis showing that naive diffusion guidance breaks the training distribution and weakens control. Extensive experiments on robotic collision avoidance, dexterous manipulation, and image generation tasks demonstrate that Coupled Guidance improves sample quality and guidance stability without extra computational overhead.
arXiv:2607. 18200v1 Announce Type: cross Abstract: Robots in cluttered indoor spaces often fail not because they cannot generate collision-free paths, but because a fixed safety margin is mis-calibrated: conservative margins cause detours and timeouts, while permissive margins lead to near-boundary shortcuts under perception bias.
