  • 用控制屏障函数设计分层安全滤波器,实时修正操作指令。
  • 实验验证可避免自由飞行时误触觉反馈,交互时反馈方向一致。
  • 适合需要高安全性的空中作业场景,如救援或精密操作。

本文提出一种面向全向空中机械臂的安全关键型双向远程操控框架,融合视觉与无力传感器的触觉力矩反馈。不同于依赖机载力/扭矩传感器或模型依赖力矩估计的方法(后者在模型不确定性下不可靠,且自由飞行时可能产生意外反馈),本方法基于控制屏障函数设计分层安全滤波器,显式考虑机械臂与环境物理交互引起的跟踪误差,并强制执行推力上限——这一因素对飞行安全至关重要但常被忽视。该滤波器调整操作者指令,确保空中操作安全稳定,防止电机饱和。滤波器的调整量映射为触觉反馈,直观传达交互信息和电机即将饱和的预警。通过六旋翼全向空中机械臂的实际实验,验证了所提方法在自由飞行中无误触觉反馈、交互时反馈方向一致,且适用于多种操作任务。消融实验进一步表明,饱和滤波器通过明确防止电机饱和提升了交互稳定性,并提示操作者采取纠正动作。

原文摘要 · Abstract (English)

This paper presents a safety-critical bilateral teleoperation framework for omnidirectional aerial manipulators that integrates visual and force-sensorless haptic wrench feedback. Unlike existing approaches that either rely on onboard force/torque sensors or use model-dependent wrench estimates, which may become unreliable under model uncertainties or induce unintended feedback during free-flight, our method implements a hierarchical safety filter based on control barrier functions to avoid such limitations. The safety filter, being the key contribution, explicitly accounts for tracking errors arising from physical interaction between the aerial manipulator and its surroundings while enforcing thrust limits, a factor overlooked despite its critical importance for flight safety. This safety filter adjusts the command from the operator to ensure safe and stable aerial manipulation and avoid motor saturation. The adjustment made by the filter is mapped to haptic feedback, which is intuitive to the operator and conveys information on physical interaction and impending motor saturation. By actual experiments with a hexarotor-based omnidirectional aerial manipulator, we demonstrate that the proposed method avoids haptic feedback during free-flight, provides directionally consistent feedback under physical interaction, and can be operated for diverse manipulative tasks. Moreover, an ablation study further shows that the saturation filter improves interaction stability by explicitly preventing motor saturation and informing the operator of corrective actions.
