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 2
Lawrence Tech is a small, non-profit, private university in an urban campus within metro Detroit James A. Mynderse MSMSE at Lawrence Tech 3
Mechanical Engineering is the largest dept. with 9 degree programs and 931 students (Spring 2016) DEME 16 MSME MSIE MSMSE MEM MSAE 69 22 55 94 221 BSME BSIE BSRE 368 22 47 James A. Mynderse MSMSE at Lawrence Tech 4
Our faculty reflect our university motto, “Theory and Practice” # Contributing to MSMSE Program Full-time Faculty 6 Adjunct Faculty 10 • Adjunct faculty are all working in or retired from local industry James A. Mynderse MSMSE at Lawrence Tech 5
Our student population reflects both our status as a private university and our location in metro Detroit Students Student Jobs Class Offerings Mostly domestic, Many start jobs in BSME Day & Evening some international junior year Most of domestic MSME Mostly international Evening Few of international 16 domestic 100% of domestic MSMSE Evening 8 international 50% of international • MSMSE numbers include 2 in-progress students not enrolled for Spring 2016 headcount James A. Mynderse MSMSE at Lawrence Tech 6
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 7
To appeal to working students, we focus on the practical • Graduating high-quality engineers with an industry focus • Applied research involving undergraduate and graduate students James A. Mynderse MSMSE at Lawrence Tech 8
We define mechatronics graphically: James A. Mynderse MSMSE at Lawrence Tech 9
The 31 credit program includes remedial coursework, 8 core courses, and 2 thesis/electives James A. Mynderse MSMSE at Lawrence Tech 10
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 11
Four MSMSE courses were borrowed from existing programs – this saves on faculty! • Low MSMSE enrollment, easy to fit students into existing courses • No additional MSMSE-specific course with associated faculty load James A. Mynderse MSMSE at Lawrence Tech 12
Required MSMSE-specific laboratory courses bookend the program • First course is exciting! • Last course is exciting! • New students get an early • Graduating students taste of design demonstrate what they have learned • Undergraduate students get • Great talking points for both lured into the program students and program James A. Mynderse MSMSE at Lawrence Tech 13
The program includes both theory and practice: Examples of each follow Theory + Practical Applications Theory Hands-On Practice James A. Mynderse MSMSE at Lawrence Tech 14
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 James A. Mynderse MSMSE at Lawrence Tech 15
“ Dextre ” is part of the international space station (ISS) mobile servicing system (MSS) James A. Mynderse MSMSE at Lawrence Tech 16
In some cases, it may be useful to operate dextre remotely via teleoperation • 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? James A. Mynderse MSMSE at Lawrence Tech 17

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 19
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 James A. Mynderse MSMSE at Lawrence Tech 20
2014 Problem: Autonomous devices to locate, collect, and dispose of simulated nuclear waste containers Deep borehole disposal is a promising option 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. James A. Mynderse MSMSE at Lawrence Tech 21
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 following release from train Randomly placed storage shed (starting location) James A. Mynderse MSMSE at Lawrence Tech 22
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! James A. Mynderse MSMSE at Lawrence Tech 23

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 25
Student-selected projects vary in quality and results but all report substantial learning James A. Mynderse MSMSE at Lawrence Tech 26
In summary, MSMSE at Lawrence Tech is an established program with a focus on theory and practice Questions? James A. Mynderse MSMSE at Lawrence Tech 27
