本文讨论了如何将广泛使用的廉价激光测距仪 (LRF) Hokuyo URG-04LX-UG01 与易于使用的 Arduino 微控制器集成到机械工程专业学生的科学、技术、工程和数学 (STEM) 程序中。由于 LRF 成本低廉，已与笔记本电脑和台式电脑一起用于多种自主机器人。此外，Arduino 微控制器由于其开源设计和成本效益而适用于教育目的。因此，将 Hokuyo LRF 与 Arduino 微控制器相结合似乎是向机械工程等非电气和电子工程学科的本科生教授机电一体化的最佳选择。然而，它们很少被整合用于 STEM 教育。在这里，我们构建了一个集成这些设备的自主机器人，并设计了一门课程，教授机电一体化的多个方面，包括控制工程、编程和嵌入式系统。机械工程专业学生的课程为期 10 周，易于实施，并且由于机器人成本较低（约 1,350 美元），因此具有较高的成本效益比。课程结束后向学生参与者进行的问卷调查结果表明，该课程提高了他们的知识、动机、兴趣和满意度。因此，我们相信这份报告将有助于提供一个STEM教育框架，让学生获得解决现实问题所需的基本技能和知识。
This paper discusses how to integrate a widely used, inexpensive laser range finder (LRF), the Hokuyo URG-04LX-UG01, with an easy-to-use Arduino microcontroller, into a science, technology, engineering, and mathematics (STEM) program for mechanical engineering students. The LRF has been used in several autonomous robots, in conjunction with laptops and desktop computers, due to its low cost. In addition, Arduino microcontrollers are suitable for educational purposes due to their open-source design and cost-effectiveness. Thus, combining the Hokuyo LRF with Arduino microcontrollers seems to be the best option to teach mechatronics to undergraduate students majoring in non-electrical and electronic engineering subjects, such as mechanical engineering. However, they have seldom been integrated for use in STEM education. Here, we built an autonomous robot integrating these devices and designed a course that teaches several aspects of mechatronics, including control engineering, programming, and embedded systems. The course for mechanical engineering students is 10 weeks in duration, easy to implement, and has a high cost-benefit ratio given the low cost of the robot (~1,350 USD). The results of a questionnaire given to the student participants upon completion of the course indicated that the course enhanced their knowledge, motivation, interest, and satisfaction. Therefore, we believe that this report will be helpful in providing a STEM education framework that allows students to acquire the basic skills and knowledge necessary to solve real-world problems.
