Our work is accepted by CoRL2026🥳
The code is releasing, feel free to try OmniGuide in sim or real!
See you in Austin🎉

VLA policies learn generalist robot behaviors from massive teleoperation datasets, hoping that the right behavior emerges. But they rarely use perception during training or inference: powerful foundation models of 3D geometry, semantics, or human motion are ignored.

@TimSong52005757, @LongLeRobot, and our @GRASPlab team introduce Omniguide, based on a simple idea: Instead of retraining policies, let perception guide action at inference time.

We express diverse guidance sources as attractive and repulsive energy fields in 3D space and inject their gradients into the generative process of VLA policies.

This lets perception modules steer actions without retraining the policy: A modular path toward composable robot intelligence.

So honored to have the support of my professors and peers, including the omnipotent Long @LongLeRobot, on my first PhD project. 3D space is the bridge between the task and action space, where the guidance from foundation knowledge flows.
