PanoFuse complements local wrist-camera observations with a 360° panoramic view, providing global scene context for long-horizon real-world manipulation.

Abstract

Vision-Language-Action (VLA) policies have shown promising performance in language-conditioned robotic manipulation, but conventional perspective cameras provide only limited fields of view and may miss global scene context under occlusion, distractors, and unseen environments. We propose PanoFuse, a panorama-enhanced VLA framework that complements local wrist-camera observations with global panoramic perception. A dedicated panoramic branch leverages a pretrained panoramic foundation model to extract complementary semantic and geometric representations. Rather than directly mixing these heterogeneous features, Decoupled Semantic-Geometric Routing (DSGR) maintains them as separate context streams and selectively routes them to downstream state and action representations through structured block-wise attention. We further develop a synchronized teleoperation pipeline and collect a real-world manipulation dataset containing panoramic RGB observations, wrist-view images, language instructions, robot states, and actions. Across seven evaluation settings, PanoFuse reaches an average success rate of 52.9% and shows consistent improvements under novel-object, unseen-background, and distractor-rich settings.

Overview

Overview of PanoFuse for real-world robotic manipulation

PanoFuse uses a wrist RGB camera for local manipulation detail and an Insta360 X5 panoramic camera for continuous 360° global context. The panoramic stream supports target acquisition, grasping, transfer, and placement across a long-horizon manipulation sequence.

Method

Panoramic semantic and geometric representations are extracted separately and selectively routed to downstream state and action representations.

Pipeline of the PanoFuse framework

Panoramic Representation

A frozen Depth Any Panoramas (DAP) model provides complementary semantic and geometric features from the equirectangular panoramic RGB observation.

64 + 64 Context Tokens

Semantic and geometric features are each pooled to an 8×8 grid and projected into the VLM embedding space.

DSGR

Structured block-wise attention keeps semantic and geometric streams separately contextualized while exposing both to downstream state and action blocks.
