PanoTac: A Dense Three-Axis Tactile Sensor for Robust Touch-Centric Manipulation
Overview
This paper introduces PanoTac, a low-cost compliant tactile fingertip sensor designed for dense three-axis sensing. Each fingertip provides a 12x32x3 tactile representation with normal and shear response components at each taxel, operating at 60 Hz for under $50 per unit. When integrated into a robotic system with a visuo-tactile pipeline, the resulting policies outperform vision-only baselines by an average of 46.7 percentage points on tasks such as grain scooping and salt pouring. Ablation studies demonstrate that removing either spatial contact information or shear feedback reduces overall performance across the task suite.
