LOUISIANA TECH UNIVERSITY MECHANICAL ENGINEERING PROGRAM College of Engineering and Science Living with the Lab • Each student owns their own “lab” consisting of – – a laptop tools (multimeter, dial caliper, wire strippers, . . . ) $80 software (Mathcad, Solid. Works, MS Office) a robot kit (the Boe-Bot) to provide a personal “lab” $100 • Student owned labs provide a way to boost hands-on learning beyond what is possible using traditional university laboratories

LOUISIANA TECH UNIVERSITY MECHANICAL ENGINEERING PROGRAM College of Engineering and Science Freshman Projects Laboratory Two classrooms designed to support the curriculum (40 students, 24 students) Classrooms allow us to easily switch between lecture, laboratory and shop activities within a single 110 minute class period.

LOUISIANA TECH UNIVERSITY MECHANICAL ENGINEERING PROGRAM College of Engineering and Science Seven “Threads” Define the Freshman Experience 1. SYSTEMS – one major project per quarter 2. ELECTROMECHANICAL – breadboarding, sensors, control 3. FABRICATION AND ACQUISITION – shop activities; locate, specify and purchase components 4. SOFTWARE – Excel, Mathcad, Solid. Works, Programming 5. FUNDAMENTALS • electricity and DC circuits • conservation of energy • basic chemistry and electrochemistry • conservation of mass • least squares fitting to calibrate sensors • statics 1. engineering economics 6.

LOUISIANA TECH UNIVERSITY Questions? MECHANICAL ENGINEERING PROGRAM College of Engineering and Science 2008 Freshman Design Expo May 7, 2008

LOUISIANA TECH UNIVERSITY MECHANICAL ENGINEERING PROGRAM College of Engineering and Science History • In 2002 we offered a pilot robotics-centered curriculum to 30 students • In 2006 we received $498, 000 NSF CCLI grant to expand the curriculum to all engineering students • In the fall of 2007 we implemented the curriculum for all students Why? • We wanted freshman design to be more than mousetrap cars and straw bridges • We wanted to progressively build skills and competence so that freshmen could implement significant projects • We wanted to make students more innovative
