用蜂窝夹紧机制实现可穿戴力反馈,让远程操作更像真手抓物。

A Wearable Stiffness-Rendering Haptic Device with a Honeycomb Jamming Mechanism for Bilateral Teleoperation

  • 采用蜂窝夹紧结构,真空控制下刚度可调(1.15–2.64 N/mm)
  • 实测显示刚度响应与力反馈误差小、相关性高,操作稳定
  • 轻量(20克)安全设计,适合远程操控和虚实交互场景

本文针对双边远程操作中难以提供本体觉反馈的问题,设计了一款可穿戴、轻量化(20克)、紧凑的触觉设备HJ-Haptic,利用蜂窝夹紧机制实现物体刚度渲染。该设备在30 kPa真空压力下,刚度可在1.15 N/mm至2.64 N/mm之间调节。我们将其集成到远程操作框架中,使操作者可根据可靠的触觉反馈实时调整抓握力度。通过三点弯曲测试和远程抓取任务验证了设备功能。实验表明,远程运动、刚度渲染与交互力反馈间具有较小的均方根误差(RMSE)和强相关性。HJ-Haptic能根据实时夹持器反馈动态调节刚度,模拟真实手部抓握感。真空系统确保了即使气体泄漏或材料失效,操作者仍安全。将HJ-Haptic融入远程操作框架,显著提升了物体刚度感知的可靠性与操作稳定性。研究证明蜂窝夹紧机制在远程操作及扩展现实交互等场景中具有广泛应用潜力。

原文摘要 · Abstract (English)

This paper addresses the challenge of providing kinesthetic feedback in bilateral teleoperation by designing a wearable, lightweight (20 g), and compact haptic device, the HJ-Haptic, utilizing a honeycomb jamming mechanism for object stiffness rendering. The HJ-Haptic device can vary its stiffness, from 1.15 N/mm to 2.64 N/mm, using a 30 kPa vacuum pressure. We demonstrate its implementation in a teleoperation framework, enabling operators to adjust grip force based on a reliable haptic feedback on object stiffness. A three-point flexural test on the honeycomb jamming mechanism and teleoperated object-grasping tasks were conducted to evaluate the device's functionality. Our experiments demonstrated a small RMSE and strong correlations in teleoperated motion, stiffness rendering, and interaction force feedback. The HJ-Haptic effectively adjusts its stiffness in response to real-time gripper feedback, mimicking the sensation of direct object grasping with hands. The device's use of vacuum pressure ensures operator safety by preventing dangerous outcomes in case of gas leakage or material failure. Incorporating the HJ-Haptic into the teleoperation framework provided the reliable perception of object stiffness and stable teleoperation. This study highlights the potential of the honeycomb jamming mechanism for enhancing haptic feedback in various applications, including teleoperation scenarios, as well as interactions with extended-reality environments.
