摘要:

远程机器人在帮助工人安全地在建筑工地上操作建筑部件方面表现出了希望;然而,它主要依赖于视觉反馈,在接触僵硬或能见度差的情况下限制了效率。可靠和经济的触觉反馈可以填补这一感知空白,并促进施工活动。因此,我们设计了一个基于音频的触觉反馈系统,该系统测量机器人工具所经历的振动,并使操作员能够实时的感觉到它们。通过优化系统的现成加速度计和音圈致动器的位置,实现了精确的触觉传输。进行了一项用户研究,以评估这种自然类型的振动反馈如何影响操作员的性能,在遥控装配。30名参与者使用双手遥控操作系统建立一个结构下,三个随机排序的触觉反馈条件:无振动,单轴振动,三轴振动。结果表明,用户利用这两种触觉反馈后,获得了一些经验的任务,导致显着降低振动和力量在第二次试验。主观反应表明,触觉反馈降低了感知的任务难度,任务持续时间和疲劳。这些结果表明,提供这种类型的振动触觉反馈的遥控工程机器人将提高用户的性能和体验。

英文摘要:

Telerobotics has shown promise in helping workers safely manipulate building components on construction sites; however, its primary reliance on visual feedback limits efficiency in situations with stiff contact or poor visibility. Reliable and economical haptic feedback could fill this perception gap and facilitate construction activities. Thus, we designed an audio-based haptic feedback system that measures the vibrations experienced by the robot tools and enables the operator to feel them in real time. Accurate haptic transmission was achieved by optimizing the positions of the system's off-the-shelf accelerometers and voice-coil actuators. A user study was conducted to evaluate how this naturalistic type of vibration feedback affects the operator's performance in telerobotic assembly. Thirty participants used a bimanual teleoperation system to build a structure under three randomly ordered haptic feedback conditions: no vibrations, one-axis vibrations, and three-axis vibrations. The results show that users took advantage of both kinds of haptic feedback after gaining some experience with the task, causing significantly lower vibrations and forces in the second trial. Subjective responses indicate that haptic feedback reduced the perceived task difficulty, task duration, and fatigue. These results demonstrate that providing this type of vibrotactile feedback on teleoperated construction robots would enhance user performance and experience.
