This talk introduces Lawrence Tech, the MSMSE curriculum, our program challenges, and our successes

Lawrence Tech MSMSE curriculum Theory and Practice

James A. Mynderse MSMSE at Lawrence Tech 3

Lawrence Tech is a small, non-profit, private university in an urban campus within metro Detroit

James A. Mynderse MSMSE at Lawrence Tech 4

Mechanical Engineering is the largest

• dept. with 9 degree programs and 931

students (Spring 2016)

• Adjunct faculty are all working in or retired from local industry

Our faculty reflect our university motto, “Theory and Practice”

• MSMSE numbers include 2 in-progress students not enrolled for

Spring 2016 headcount

Our student population reflects both our status as a private university and our location in metro Detroit

Student time investment, interest, and aptitude varies widely

Working students have little time for coursework and studying

• Work hours range from 40-60 per week
• Some students traveling 1-3 weeks during semester

Research in the program is minimal

• 23 graduates since May 2013 (zero completed theses)
• 21 in-progress (3 in-progress theses)

James A. Mynderse MSMSE at Lawrence Tech 8

• Graduating high-quality engineers with an industry focus
• Applied research involving undergraduate and graduate students

To appeal to working students, we focus

• n the practical

We define mechatronics graphically:

James A. Mynderse MSMSE at Lawrence Tech 10

The 31 credit program includes remedial coursework, 8 core courses, and 2 thesis/electives

James A. Mynderse MSMSE at Lawrence Tech 11

Program curriculum is tied to our graphical definition of mechatronics

Mechanical Systems

• Vibrations
• Dynamics

Control Systems

• Modern Control Systems
• Digital Control Systems
• Advanced Control Systems (elective)

Electronic + Computer Systems

• Mechatronic Systems 1 (lab)
• Mechatronic Systems 2 (lab)

James A. Mynderse MSMSE at Lawrence Tech 12

• Low MSMSE enrollment, easy to fit students into existing courses
• No additional MSMSE-specific course with associated faculty load

Four MSMSE courses were borrowed from existing programs – this saves on faculty!

James A. Mynderse MSMSE at Lawrence Tech 13

Required MSMSE-specific laboratory courses bookend the program

• First course is exciting!
• New students get an early

taste of design

• Undergraduate students get

lured into the program

• Last course is exciting!
• Graduating students

demonstrate what they have learned

• Great talking points for both

students and program

James A. Mynderse MSMSE at Lawrence Tech 14

The program includes both theory and practice: Examples of each follow

Theory Hands-On Practice Theory + Practical Applications

Modern Control Systems is a mid-level graduate course and a technical elective for undergraduates

• Topics:
• Review of classic control design
• “Advanced” classical control design
• State-space analysis
• State-space design
• Extensive use of MATLAB
• Case studies are being developed for each lecture topic
• 14/28 lectures have associated case studies
• Introduced in lecture, completed as homework
• Assessment planned for Spring 2017

“Dextre” is part of the international space station (ISS) mobile servicing system (MSS)

James A. Mynderse MSMSE at Lawrence Tech 17

• How long does it take for a signal to move from Earth’s surface to

the ISS?

• How long would it take if Dextre was in use on the Moon?

In some cases, it may be useful to operate dextre remotely via teleoperation

James A. Mynderse MSMSE at Lawrence Tech 18

Design a control system!

1. Build a Simulink model of the plant with time delay 2. Design a PID controller for the plant without time delay 3. Test the PID controller on plant with time delay 4. Apply Smith predictor in Simulink 5. Test the PID controller with Smith predictor

Mechatronic Systems 1 is an entry-level graduate course and a technical elective for undergraduates

• Lecture topics:
• Mechatronic design
• Sensors and actuator integration
• Finite state machines
• 7 structured labs using Arduino Uno platform
• Group problem-based learning (PBL)

design task

James A. Mynderse MSMSE at Lawrence Tech 20

The PBL spans the entire semester and includes lecture and lab sessions

Lecture topics and lab experiments form an integral part of the design experience

• Rooted in the context of the

problem

• Must loop back to the design

problem Lab experiments can be tailored to the needs of the project Assessment in Fall 2014, 2015 showed improvement over previous course offering

Deep borehole disposal is a promising

• ption for nuclear waste disposal [4]... A

2-5 km deep borehole is drilled and spent nuclear fuel and high-level radioactive waste are lowered into the borehole. To aid in collection of the nuclear waste, the federal government is investigating the use of a specialized train for transportation of the waste to a storage location [7]. Your team must design and build an autonomous robot capable of retrieving sealed containers of nuclear waste from the specialized train and transporting them to the borehole for disposal.

2014 Problem: Autonomous devices to locate, collect, and dispose of simulated nuclear waste containers

James A. Mynderse MSMSE at Lawrence Tech 22

Students were provided with a sketch of the borehole facility to be used in the prototype demonstration

Dummy nuclear waste containment devices

• Spheres with 2.63” diameter

(tennis balls)

• Random distribution

2015 Problem: Bridge Inspection Before Catastrophic Failure

It is a commonly accepted fact that the infrastructure of the United States is crumbling due to insufficient funding, inattention, and insufficient political will [1-2]. Some notable bridge failures include the I-75 bridges in metro Detroit [5] and the I-65 bridge over Wildcat Creek in Indiana [6]. Your team will compete for the contract to build, operate, and maintain a fleet or bridge inspection robots to be used throughout the state. To win the contract, your team will design, build, and demonstrate a prototype system to locate and mark bridge damage. Because the contract calls for a fleet of robots, cost matters!

Mechatronic Systems 2 is an upper-level graduate course

• Lecture topics:
• Continuous controller design
• Discrete controller design
• Controller implementation using DSP/FPGA/microcontroller
• Lab practice using NI cRIO, STM32 ARM processors
• Group design task including controller design and implementation

James A. Mynderse MSMSE at Lawrence Tech 26

Student-selected projects vary in quality and results but all report substantial learning

James A. Mynderse MSMSE at Lawrence Tech 27

In summary, MSMSE at Lawrence Tech is an established program with a focus on theory and practice Questions?
