A Precise Real-Time Force-Aware Grasping System for Robust Aerial Manipulation
🤖 AI Summary
This work addresses the lack of lightweight, low-cost force sensing in conventional aerial manipulation, which hinders safe grasping of fragile objects and precise physical interaction. The authors propose a skin-inspired tactile sensing system based on magnetic induction, integrating six low-cost three-axis force sensors with a reference Hall sensor to enable high-precision omnidirectional force measurement through geomagnetic interference compensation. The system employs a fully onboard architecture, eliminating the need for external motion capture and supporting real-time grasp control and payload weight estimation. Experimental results demonstrate that the approach effectively safeguards delicate objects—such as balloons—during dynamic manipulation tasks involving varying loads, significantly enhancing the practicality and deployment ease of force-aware aerial manipulation.

📝 Abstract
Aerial manipulation requires force-aware capabilities to enable safe and effective grasping and physical interaction. Previous works often rely on heavy, expensive force sensors unsuitable for typical quadrotor platforms, or perform grasping without force feedback, risking damage to fragile objects. To address these limitations, we propose a novel force-aware grasping framework incorporating six low-cost, sensitive skin-like tactile sensors. We introduce a magnetic-based tactile sensing module that provides high-precision three-dimensional force measurements. We eliminate geomagnetic interference through a reference Hall sensor and simplify the calibration process compared to previous work. The proposed framework enables precise force-aware grasping control, allowing safe manipulation of fragile objects and real-time weight measurement of grasped items. The system is validated through comprehensive real-world experiments, including balloon grasping, dynamic load variation tests, and ablation studies, demonstrating its effectiveness in various aerial manipulation scenarios. Our approach achieves fully onboard operation without external motion capture systems, significantly enhancing the practicality of force-sensitive aerial manipulation.
