Mechatronics
What is Mechatronics?
Mechatronics is the
synergistic combination of
precision mechanical
engineering, electronic
control and systems thinking
in the design of products and
manufacturing processes.

Vision Statements
• Teach our students to learn to design and build electro-mechanical
systems, and intelligent machines and products
• Teach them to be able to function in environment that
fosters interdisciplinary activities
• Prepare them for industrial positions
• Prepare them to succeed as researchers in graduate schools
and research laboratories
The George W. Woodruff School of Mechanical Engineering
How Are Vision Statements Accomplished?
By:
• Class lectures
• Lab assignments
• Oral presentations
• Report writings
• Collaborative learning (working in teams)
The George W. Woodruff School of Mechanical Engineering
Course Format
In-class lectures
• Class meets 3 hours per week
• Lecturing is done by instructor
• Students can participate in lecturing (optional)
Laboratory Experience
Electronic Exercises
• Done by individual student
• Takes each student about 1 hour per week to complete each one
• Three Electronic Exercises (1, 2 and 3) are assigned:
Overview of test equipment, soldering and RC filters
555 Timer and its applications
Stepper motor controller and driver
The George W. Woodruff School of Mechanical Engineering
Course Format
Group Lab Exercises
• Done in groups of 3 students
• Each group spends about 3 hours every two weeks to
complete
• Four group lab exercises are assigned per semester
 Interfacing host computer with MC9S12C32 and sequencing
light emitting diodes.
 Strain gage data acquisition using A/D conversion
 DC motor control using interrupts and pulse width modulation
(real-time control)
 Programmable logic controller (PLC)
Note: Each lab assignment is demonstrated; and only two lab
exercises require report

TYPICAL STUDENTS PROJECTS in ME
8843
• ME 8843 is advanced mechatronics course
 It is project based
 Can be taken by students who have completed either ME 4447 or ME
6405 (Introduction to Mechatronics)
 Some undergraduate students with high GPAs can be allowed to
register for ME 6405
 Currently ME 4447 and ME 6405 are taught together, but students who
registered for ME 6405 are required to do more in class
