    ABSTRACT: A contest-oriented project for undergraduate students to learn implementation skills and theories related to intelligent mobile robots is presented in this paper. The project, related to Micromouse, Robotrace (Robotrace is the title of Taiwanese and Japanese robot races), and line-maze contests was developed by the embedded control system research group of the Department of Electronic Engineering, Lunghwa University of Science and Technology, Taiwan. It targets both those students who have to earn credits for a one-year special topics course and those who are just interested in making robots, and it is designed to motivate them to learn digital motion control, path planning, attitude correction, curvature detection and maze-solving algorithms. The students begin by getting acquainted with the development environment of microcontrollers, the characteristics of different sensors, and servomotor control techniques. Having learned these basic skills, they acquire further specific advanced skills and proceed to design their own mobile robots to compete in contests. The special topics course students' robots must pass examination by five teachers. Blogs and a wiki Web site for recording students' progress and experiences enhance the project's learning outcomes. Although not every student wins a prize in the contests, student feedback still shows that the contest-oriented project did motivate them to acquire the skills necessary to build and operate intelligent mobile robots.

    ABSTRACT: The development of a versatile kit to raise student interest in learning the implementation skills of intelligent mobile robots is presented in this paper. The kit is capable of solving micromouse mazes, line mazes, and following line tracks with different curvatures at different speed settings. It is first devised to be used in various project-oriented hands-on laboratory courses for students in the department of electronic engineering of Lunghwa University of Science and Technology, and introductory workshops for vocational high school students and teachers with electronic and information engineering backgrounds. To enhance the learning outcomes, contests can also be organized for students to see how well the techniques learned in the laboratory are applied in their mobile robots.

    ABSTRACT: The widespread use of robots in many areas makes the fundamental understanding of them a necessity for many electronic system design engineers. Therefore, to effectively speed up the learning process, the applications of learning-by-doing hands-on laboratory to help students get acquainted with the design and implementation of robots is inevitable. Lunghwa University has teamed up with local microcontroller manufacturers to redesign course contents, to host free workshops supported by the Ministry of Education, and to hold national contests for intelligent mobile robots. The devised low cost educational robot kits and multimedia lecture notes not only reinforce the hands-on laboratory exercises, but also help motivate students to learn actively the intelligent mobile robots.

    ABSTRACT: A project-based laboratory for learning embedded system design with support from industry is presented in this paper. The aim of this laboratory is to motivate students to learn the building blocks of embedded systems and practical control algorithms by constructing a line-following robot using the quadratic interpolation technique to predict the line position. For those students who have acquired basic microcontroller hardware and software programming skills from previous courses, the hands-on exercises in the laboratory include several specific hardware circuits and software algorithms for the final project of constructing the line-following robot. The students are allowed to discuss the hardware and software problems with each other while solving each exercise, although they have to answer the teacher's questions individually to earn the score. To enhance the learning outcomes, a racing contest for the students' line-following robots is also organized to see how well the techniques learned in the laboratory are applied in the final project. The support from the local branch of Microchip Inc. allows students to obtain C-compilers and microcontrollers at no cost. The feedback from students shows that the final project of constructing line-following robots and the racing contest motivates the students to learn actively all the skills included in the laboratory for embedded system design.

In addition to the basic hardware and software skills, several specific hardware circuits and software algorithms are included for the final project of line following robot construction. The students are allowed to discuss with the other groups of students to solve both the hardware and software problems in each experiment, although they have to answer the teacherpsilas questions on their own to get the score. To enhance the learning outcomes, a racing contest for the studentspsila line following robots is also organized to see how well the techniques learned in the laboratory are applied in the final project. The support from the local branch of Microchip Inc. lets students obtain microcontrollers at no cost. The feedbacks of students show that the final project of constructing line following robots and the racing contest really motivate the students to learn and verify actively all the skills included in the laboratory.

    ABSTRACT: Recently, the increasing demands for high efficient power conversion systems and the rapid advancement in semiconductor devices have made the power converter design technique a necessity for electronic engineers. To speed up the learning process, the problem- based learning approach and behavior model simulations are used to redesign the first power converter design course in Lunghwa University of Science and Technology. Problems and course materials are carefully devised to help students acquire the knowledge to systematically design a power converter, to implement the converter by using PWM control ICs, and to validate its performance via behavior model simulations. The course by using problem based learning approach will also prepare students the skills in 1) logical analysis, 2) drawing a conclusion from group discussions, and 3) cooperation with others. The feedbacks of the students from the midterm and final examinations, the questionnaires, and the answers to the teacher's quizzes during classes show the effectiveness of this approach.

    ABSTRACT: Making profits is the key objective for most industrial companies, but in our case, it is sacrificed to educate qualified and creative microcontroller hardware and firmware engineers. Holtek semiconductor Inc. donates its microcontroller integrated design modules and technical support to setup a laboratory in Lunghwa University for learning activities. Lunghwa University offers its resources, including teachers and facilities, to redesign course contents, hardware and software teaching materials, and propose a new program for the design of microcontroller and embedded systems. A creativity contest with high prize (<sup>S</sup>D 18000 in total) for the design of microcontroller and embedded systems using Holtek's microcontrollers is also initiated to attract more senior high school and university students to show their creativities and technical skills. The proposed program will also encourage enrolled students to win certificates provided by the Taiwan Embedded Microcontroller Development Institute, because the Institute is supported by the government and local industries

    ABSTRACT: This paper presents a home automation module with programmable control instructions (PCIs). Although it is implemented by using a low-cost 8-bit microcontroller with only 8 Kbytes of ROM spaces, a time-sharing task scheduler and 10 PCIs are included in the firmware. Timer and counter control, logic functions, and temperature control are examples of PCIs. Thanks to the design of pseudo nodes, these PCIs can also be combined to implement more complex functions that home automation needs. These modules, up to 65536 theoretically, share the same IP address, and can be found over the network via different port numbers. No dedicated home server is necessary because the network communication (TCP/IP) is handled by the module. A remote control and monitoring software is also developed to let users control the home automation modules on the Internet. The programmable home automation module has a lower cost and better cost/performance ratio than current home automation modules
