FingerViP: Learning Real-World Dexterous Manipulation with Fingertip Visual Perception

Abstract:Current dexterous manipulation systems commonly rely on external or wrist-mounted cameras for visual feedback. However, such sensing setups are prone to occlusion and can limit performance on tasks requiring close-range, multi-view perception. In this work, we design a vision-enhanced fingertip module that brings clear visual perception directly to the fingertips and present FingerViP, a learning system that leverages fingertip visual perception for dexterous manipulation. Specifically, the fingertip module integrates miniature-camera sensing within compact-footprint hardware and is installed on each finger of a multi-fingered hand, which substantially improves visual perception by providing comprehensive, multi-view observations of objects and surrounding environment. Building on the integrated fingertip modules, we develop a diffusion-based whole-body visuomotor policy conditioned on a third-view camera and multi-view fingertip vision, enabling the robot to effectively learn complex manipulation skills directly from human demonstrations. To improve view-proprioception alignment and contact awareness in the policy observation representation, each fingertip visual feature is augmented with its corresponding camera-pose encoding and per-finger joint-current encoding. We validate the effectiveness of multi-view fingertip vision and demonstrate the robustness and adaptability of FingerViP across a range of challenging real-world tasks, including retrieving objects behind an occluding curtain, achieving a $56.6\%$ relative improvement in average success rate over the baseline using an external third-view camera and a wrist-mounted camera.
