COURSE SYNOPSIS
 This course enables the students to comprehend
and identify theoretical design as well as the
machine elements that need to be considered in
machine design process.
 This course also encourages the students to think
as a machine designer.
 The concept and principle of machine design will
be applied in designing machine, focusing on the
outcome of creative and innovative student
thinking.

COURSE SYNOPSIS
 The course starts with the principle of basic design
concept and design phases.
 It concentrates on the dynamics of machine
design, as required in mechatronic program.
 The basic element of dynamics will be reviewed,
such as kinematics of machinery, velocity and
acceleration analysis.
 The components of machine design will include
gear systems, power screws, belts and chain
drive; cams, shafts, and bearings maybe added.

COURSE SYNOPSIS
 Introduction to robotics may also be added so this
course wil be useful for robotics courses later.
 Students will be exposed to the laboratory work
and research using MATLAB; other software may
be introduced.
 Students are required to provide a technical report
on selected engineering products or to develop a
product design.
 Class activities will be conducted to
enhance students’ skills and knowleges.

LIST OF EXPERIMENTS
1) Position Analysis
2) Velocity Analysis
3) Acceleration Analysis
4) Linkage Synthesis

LEARNING APPROACH
 Lecture : 48 Hours (75%)
 Practical : 8 Hours (12.5%)
 Tutorials : 8 Hours (12.5%)
 Students are required to follow all lectures and
tutorials given in the class, conduct all
experiments in the lab, and do all quizzes, tests,
and assignments.
 There should be two-way communications
between the lecture and the students.

EVALUATION CONTRIBUTION
 Final examination: 60%.
 Mid test: 10%
 Course work: 30%.
 Course work contribution:
 Practical work: 15%
 Assignments/Daily Tests : 10%
 Project: 5%
 If there is no project, Assignments/Dayly tests will
be 15%

 There will be three (3) assignments given, either
individual or group.
 Students must submit their assignments on the
stipulated date. Late submission will result in the
deduction of the mark from 10% to 100%!
 If a student cannot submit an assignment due to
any reason on the stipulated date, he or she must
submit it before the date. He or she can submit the
assignment through his or her friend.
 There is no reason for not submitting assignments.

 There will be three (3) tests given. Students who
do not submit their test papers are considered to
be absent from the class at the date of the test.
 Assignments and tests which have been marked
will be returned to the students on the stipulated
date.
 If the assignments or the tests are not returned by
the lecturer on the stipulated date, the students
will get 80% of the full marks for the assignments
or the tests.

MINGGU ULANGKAJI / REVISION WEEK
• Time to refresh your memory about what you have
done so far!
• Remember, this is not the time where you start to
learn your subject before your final exam! It will be
quite late!
• You should study hard from the first week!
Otherwise you may cry because you cannot solve
the final exam questions!

 Any question?
 If you have questions, you had better ask me now.
 The longer you keep it in your head, the less you
will understand later.
 If you are shy to ask any question in this class, you
can ask me later.
 You can also come to see me directly in my room.
But please make an appointment first.
 If you like, you can ask me through email or phone
me. But please don’t send me sms.

Don’t Worry, Be Happy!
It is not work that kills men; it is
worry.
Worry is rust upon blade.
Henry Ward Beecher

Dare To Dream
You see things; and you say
“Why?”
But I dream things that never were;
and I say “Why not?”
George Bernard Shaw
