Focus on Applications: HRI for Teleoperation
摘要
This work presents the usage of a device for teleoperation tasks, specifically evaluating the impact of wearable haptics for force feedback in teleimpedance control for dual-arm robotic teleoperation. Robotic teleoperation enables humans to safely complete exploratory procedures in remote locations, such as deep-sea exploration or building assessments following natural disasters. Successful task completion in these environments requires meaningful dual-arm robotic coordination and a proper understanding of the environment, capabilities that are inherent to humans via impedance regulation and haptic interactions but challenging to achieve in telerobotic systems. Teleimpedance control has facilitated impedance regulation in such applications, while bilateral teleoperation systems aim to restore haptic sensation to the operator, often at the expense of stability or workspace size. Wearable haptic devices, such as the Clenching Upper-Limb Force Feedback (CUFF), have the potential to inform the operator of key forces during task completion while maintaining stability and transparency. In our study, able-bodied participants completed a peg-in-hole, box placement task, aiming to seat as many boxes as possible within the trial period. Experiments were conducted using both transparent and opaque boxes. With the opaque boxes, participants achieved a higher number of successful placements with haptic feedback, and the experimental trend showed higher mean interaction forces. Results suggest that the provision of wearable haptic feedback may increase operator confidence when visual cues are obscured.
