  • 无需修改硬件,适用于多种手套和用户,适合机器人操作数据采集

触觉手套可数字化手与物体交互时的接触与力信息,广泛应用于灵巧操作、远程操控和示范学习。为保持手部灵活性并捕捉自然交互细节,这类手套及集成的触觉传感器通常设计为柔软、柔韧且舒适。然而,此类柔性传感器不仅对接触力敏感,也易受手姿变化影响,产生姿态相关伪影(PRAs)。PRAs在低力范围内尤为严重,导致接触误检或延迟检测,从而提高手套的最小可检测力(MDF)。本文系统分析了PRAs与手姿及力之间的关系,提出一种无需修改手套的算法框架,利用日益普及的手姿信息来缓解该问题。所提姿态感知力估计模型在触觉到力的管道中增加残差预测分支,显式建模姿态引起的传感器形变。我们在3种手套设计和15名用户上验证该方法,使最小可检测力分别降低10.4%、12.2%和18.3%,各项指标均有稳定提升。该方法为提升触觉手套在数据采集和多样机器人应用中的可用性提供了实用路径。

原文摘要 · Abstract (English)

Tactile gloves digitize contact and force during hand-object interactions, enabling robotics applications in dexterous manipulation, teleoperation, and learning from demonstration. To preserve hand dexterity and capture the nuances of natural interactions, these gloves and the integrated tactile sensors are designed to be soft, flexible, and comfortable. However, such flexible sensors are sensitive not only to contact forces but also unavoidably to hand pose changes, resulting in pose-related artifacts (PRAs). PRAs are especially problematic in the low-force range, resulting in misdetections or late-onset detections of contact, which raises the minimum detectable force (MDF) of the glove. In this work, we characterize the PRAs in relation to pose and force. Building on these insights, we introduce a glove-agnostic algorithmic framework that leverages hand pose information, which is increasingly available, to mitigate PRAs without glove modifications. Our pose-aware force estimation model augments tactile-to-force pipelines with a residual prediction branch that explicitly accounts for pose-induced sensor deformations. We validate our approach across 3 glove designs and 15 users, reducing MDF by 10.4%, 12.2%, and 18.3%, with consistent improvements across all evaluated metrics. This method provides a practical path to improving the usability of tactile gloves in data collection and diverse robotic applications.
