ENGG 1100: Introduction to Engineering Design

1. ENGG 1100: Introduction to Engineering Design Introduction Professor Lian K. Chen Department of Information Engineering Sep. 2, 2013 Acknowledgment: Some slides are from prior years’ lecture notes by my colleagues

2. Welcome to Faculty of Engineering ENGG 1100!

3. Overview • This is a hands-on project-based course. • You will work in groups on a hardware project.(2 students/group) • This term we will build an automatic guided vehicle. • We will teach you the basic knowledge to realize the goal, with support from mentors (professors), technical staffs, and teaching assistants. • We intend to show you and let you experience • Basic mechanical design, electronic principles and concepts • Experimental skills • Methodology for design & construction of a system • We also hope that by the end of the term, you would demonstrate innovations, teamwork, and good communication skills. The Chinese University of Hong Kong 3

4. Learning Outcomes • Understand basic mechanical design, electronics principles and appreciate their importance; • Gain basic engineering skills on the use of CAD software, instrumentation, hardware construction and testing; • Understand engineering design processes and systematic approaches to solving engineering problems; • Learn teamwork by working and communicating with your peer as a team towards milestones. The Chinese University of Hong Kong 4

5. The Project • You are required to design and build a mini Automatic Guided Vehicle (AGV) to move from a starting point, detect and pick up an object and bring it to the destination autonomously. • What is AGV[1]: • “An automated guided vehicle or automatic guided vehicle (AGV) is a mobile robot that follows markers or wires in the floor, or uses vision or lasers.” • “They are most often used in industrial applications to move materials around a manufacturing facility or a warehouse..” [1]: http://en.wikipedia.org/wiki/Automated_guided_vehicle The Chinese University of Hong Kong 5

7. Project Outcome (Video) • http://www.youtube.com/watch?v=zQqSbyl-A-k • The functions performed: • A moving vehicle • A guiding mechanism (in this case : a magnetic strip taped underneath the paperboard and two magnetic sensors) • A sensor to detect the soda can (in this case: a magnetic sensor switch) • A gripper to grip the soda can when it is detected • An end point detection mechanism to release the soda can when AGV reaches the destination The Chinese University of Hong Kong 7

8. Project Outcome (Example) Looks so complicated! Luckily you do not need to design this circuit. • The AGV The Chinese University of Hong Kong 8

13. Important dates to note: • Week 1: group forming. Find a peer to form a group with you. The group size is 2. Make sure your partner is registered to the same lab session as yours. You are required to register with your partner using the CU eLearning System. Group sign up procedure is provided to you in the “Elearn Information.pdf” document in eLearn. You must sign up by Sep 6. 2013 (Friday); otherwise, you will be randomly assigned to a partner. • All homework deadlines are at 5:30pm of the listed dates. • Week 14: submission of the final project report. The deadline is on Dec. 9, 2013 (Monday), at 5:30pm. The Chinese University of Hong Kong 13

14. Assessment • Laboratory and Homework – 30% • Multiple Choice Quiz – 10% • Mid-term Test Run (Car Prototype) – 10% • Project Progress (Meetings with Mentor) – 15% • Demo 1 – 10% • Demo 2– 15% (optional; for students to get A and A-) • Final Report – 10% The Chinese University of Hong Kong 14

15. Plagiarism & Academic Honesty • As a CUHK student, you are respectfully requested to observe and acknowledge the academic honesty in academic works, which is the core value of higher learning. • We adopt a policy of zero tolerance on plagiarism. Disciplinary actions, usually involving severe penalties, will be taken for detected plagiarism cases. • Please see the following 2 documents for details: • “Guidelines to Academic Honesty,” Faculty of Engineering, CUHK, August 2012, http://www.erg.cuhk.edu.hk/erg-intra/upload/documents/ENGG_Discipline.pdf (intranet access only) • “Honesty in Academic Work: A Guide for Students and Teachers,” CUHK, August 2012, http://www.cuhk.edu.hk/policy/academichonesty/ • Simply put, don’t copy, don’t buy solution, just honestly do your work, and credit others’ contribution. The Chinese University of Hong Kong 15

16. Student/Faculty Expectations on Teaching &Learning • Learning process in university environment is an interactive engagement between faculty members and the student body. The Faculty of Engineering has always placed a strong emphasis on quality teaching and learning. • With a view to building up an atmosphere of mutual respect, acknowledgement, and responsibility between our students and faculty members as well as to enhancing teaching and learning in the Faculty, the Faculty has clearly established a balanced set of expectations for the students and faculty members of our Faculty: • “Student/Faculty Expectations on Teaching and Learning,” Faculty of Engineering, CUHK, 29 August 2011, http://www.erg.cuhk.edu.hk/erg-intra/upload/documents/StaffStudentExpectations.pdf The Chinese University of Hong Kong 16

17. Group Forming • Most of the course assessment will be group-based. • Find a peer to form a group with you by 06 Sep 2013 5:30pmin the CU eLearning System • Group sign up procedure is available in the “Elearn information.pdf” document in eLearn. • Make sure your partner is registered to the same lab session as yours. • Otherwise you will be randomly assigned to a partner.

20. Laboratory Rules • Laboratory preparation is vital for you to conduct the lab works. Prior to each lab, please • Read the lab manual, • Prepare lab sheet according to the lab manual, and • Bring the lab sheet to the lab with you. • Laboratory safety is very important! Strict observation of the Laboratory Safety Instructions listed in the homepage (http://www.cuhk.edu.hk/useo/) of the University Safety & Environment Office on the handling of Electrical and Electronic instruments and power sources is mandatory. • Please don’t eat or drink in the laboratory. • Be punctual. Attendance will be checked, and 1 mark will be deducted for those who are late for more than 15 minutes. The Chinese University of Hong Kong 20
