The Missing Touch: Spatially Distributed Tactile Feedback Brings Teleoperation Closer to Human Dexterity

研究用二自由度力反馈遥操作器和32自由度触觉显示验证，空间分布式触觉反馈可提升遥操作表现并更接近人类动作。

核心要点

• 遥操作常用于采集示范，但即使基础任务表现仍明显低于人类灵巧性。
• 方法是在操作者指尖忠实再现远端操纵器的局部变形和分布式接触信息。
• 任务中该反馈加快完成，减少纠正动作和步骤，使轨迹偏差降低29–79%。
• 更高触觉反馈分辨率压缩遥操作运动的状态空间分布，关联更好策略训练结果。

验证范围与局限：验证限于二自由度双边力反馈遥操作器配合32自由度触觉指尖显示器的一系列遥操作任务。

英文摘要 (Abstract)

A fundamental challenge in robotic teleoperation is enabling an operator to control a remote robot as effortlessly and intuitively as their own hands. Despite the growing use of teleoperation to collect demonstration data for training autonomous robot policies, teleoperated robot performance still falls significantly short of human dexterity, even for basic tasks. Here, we present evidence that a key factor contributing to this performance gap is the absence of spatially distributed tactile feedback. Using a two-degree-of-freedom (DoF) bilateral force-feedback telemanipulator paired with a 32-DoF tactile fingertip display, we show that operator performance improves significantly when localized deformations on the remote manipulator are faithfully reproduced on the operator's fingertip. In a series of teleoperation tasks, reproducing distributed contact information not only accelerated task performance but also brought teleoperated movements closer to natural human behavior by minimizing corrective actions and task completion steps, thereby reducing the deviation between teleoperated and natural trajectories by 29$\unicode{x2013}$79%. Furthermore, we found that increasing the resolution of the tactile feedback$\unicode{x2014}$by refining how finely the measured displacements were quantized for reproduction$\unicode{x2014}$compressed the state-space distribution of teleoperated motions, which has been associated with improved training outcomes for autonomous robot policies. Together, these results suggest that spatially distributed tactile feedback is essential for closing the gap between human and teleoperated dexterity and training the next generation of autonomous robots.
