GHOST: Hierarchical Sub-Goal Policies for Generalizing Robot Manipulation

arXiv:2606.10025v1 Announce Type: cross Abstract: We present GHOST, a framework for learning visuomotor manipulation policies that generalize beyond the training distribution. GHOST factorizes control into (i) a high-level policy that predicts the next sub-goal as a distribution over 3D end-effector poses from multi-view RGB-D observations, and (ii) a low-level goal-conditioned controller that executes embodiment-specific actions. To condition image-based policies on 3D goals, we introduce a simple spatial interface that projects predicted goals into the image plane and represents them as end-

Why this matters
Why now

The continuous advancements in AI and robotics, coupled with increasing demand for robust generalization in real-world applications, make this research timely.

Why it’s important

Sophisticated readers should care because improved robot manipulation generalization is a critical step towards autonomous systems in diverse unstructured environments, impacting labor, supply chains, and industrial automation.

What changes

This framework demonstrates a method for robots to learn and adapt to tasks beyond their initial training, moving towards more flexible and less task-specific robotic deployments.
