用手机操控机械臂，让远程学生也能动手做实验。
TeleopLab: Accessible and Intuitive Teleoperation of a Robotic Manipulator for Remote Labs
- 通过手机界面+自适应夹具，实现低成本远程操控机械臂
- 用户熟悉后任务时间减少46.1%，工作负荷仅38.2（满分100）
- 适合远程STEM教学，提升学生实操体验与学习积极性
遥操作为远程教育中的动手学习提供了可行方案，尤其适用于需接触真实设备的场景。然而，现有远程体验往往成本高或不够直观。为此，我们提出TeleopLab——一个基于移动设备的遥操作系统，使学生可通过智能手机控制机械臂完成实验操作。该系统包括机械臂、自适应夹具、摄像头、多样化实验设备、移动端用户界面及视频通话软件。我们开展了用户研究，评估任务表现、学生反馈、可用性与工作负荷。结果表明，随着对系统的熟悉，任务完成时间平均缩短46.1%。量化反馈显示学生态度明显改善，NASA TLX评分显示工作负荷为38.2，系统可用性量表（SUS）得分为73.8。TeleopLab有效弥合了实体实验室与远程教育之间的差距，构建了一个可扩展、高效的远程STEM学习平台。
原文摘要 · Abstract (English)
Teleoperation offers a promising solution for enabling hands-on learning in remote education, particularly in environments requiring interaction with real-world equipment. However, such remote experiences can be costly or non-intuitive. To address these challenges, we present TeleopLab, a mobile device teleoperation system that allows students to control a robotic arm and operate lab equipment. TeleopLab comprises a robotic arm, an adaptive gripper, cameras, lab equipment for a diverse range of applications, a user interface accessible through smartphones, and video call software. We conducted a user study, focusing on task performance, students' perspectives toward the system, usability, and workload assessment. Our results demonstrate a 46.1% reduction in task completion time as users gained familiarity with the system. Quantitative feedback highlighted improvements in students' perspectives after using the system, while NASA TLX and SUS assessments indicated a manageable workload of 38.2 and a positive usability of 73.8. TeleopLab successfully bridges the gap between physical labs and remote education, offering a scalable and effective platform for remote STEM learning.
