Object-centric representations boost robotic imitation learning

By PulseAugur Editorial · [1 sources] ·

Researchers have developed an object-centric representation approach for visuomotor imitation learning in robotics. This method groups features into per-object slots, offering a structured alternative to traditional global scene embeddings or dense patch grids. Experiments on the ManiSkill3 PickCube-v1 benchmark showed that this object-centric representation, using a frozen DINO ViT-B/16 encoder with Slot Attention, achieved a 55.0% success rate, significantly outperforming a dense DINO global-feature baseline. Further enhancements, including explicit 2D spatial goals and native-resolution rendering, improved the system's performance closer to an oracle upper bound, while a failure taxonomy identified occlusion as a key bottleneck.

IMPACT This research could lead to more robust and efficient robotic manipulation systems by improving how robots perceive and interact with objects.

    More Structure, Not More Capacity: Object-Centric Representations for Visuomotor Imitation Learning

    arXiv:2607.09825v1 Announce Type: cross Abstract: Robotic manipulation policies rely on pre-trained vision models that give either a global scene embedding or a dense patch grid. Both mix task-relevant and task-irrelevant features. Object-centric slot representations are a struct…
