ViHaTeleop: A Low-Cost, Lightweight Visual-Haptic Teleoperation System for Dexterous Manipulation Learning
ViHaTeleop以视觉追踪和逐指振动反馈采集接触示教,并在仿真与真机接触任务中验证。
核心要点
- 低成本遥操作硬件难以采集高质量、接触关键的灵巧操作示教。
- 系统结合SLAM腕部追踪、相机手部追踪和逐指LRA振动反馈。
- 九名参与者六项任务中,触觉使全部任务成功率提升2.2至15.6个百分点。
- 初步策略训练显示,触觉线索在插孔子任务较纯视觉提升17个百分点。
验证范围与局限:验证包括Franka + LEAP Hand + 9DTact在真实与仿真环境中的六项接触关键任务,以及初步下游策略训练。
英文摘要 (Abstract)
Learning from demonstration is a promising approach for dexterous manipulation, but collecting high-quality contact-critical demonstrations remains difficult with low-cost teleoperation hardware. We present ViHaTeleop, a lightweight (0.7 kg), low-cost ($550) visual-haptic teleoperation system with SLAM-based wrist tracking, camera-based hand tracking, and finger-wise vibrotactile feedback through Linear Resonant Actuators (LRA). The system includes several design choices (LED illumination, fisheye hand camera, and tactile-aware retargeting constraints) and is deployed on Franka + LEAP Hand + 9DTact in both real and simulated environments. Under matched with/without-haptic conditions with nine participants across six contact-critical tasks, haptics improved success rates across all tasks (+2.2 to +15.6 percentage points), while completion-time effects were task-dependent. Subjective ratings showed significant gains in contact clarity and grasp confidence in both simulation and real-world settings (Wilcoxon signed-rank, $p<0.05$). We also integrate a lightweight depth-camera-based tactile proxy in Isaac Sim, enabling a full pipeline from multi-modal demonstration collection to visual-tactile policy training. Preliminary downstream validation by training visual-tactile policies from collected demonstrations shows tactile cues benefit contact-critical subtasks (peg-in-hole: +17 percentage points over vision-only).
