Mechatronics technology emerged from the fusion of Mechanical Engineering, Electrical Engineering and Computer Science. In order to accommodate this emergent technology in the engineering curriculum, the Mechanical Engineering Department developed an interdisciplinary mechatronics laboratory and a course (in collaboration with Electrical Engineering) with support from the National Science Foundation and the Louisiana Board of Regents.
The present mechatronics laboratory includes various physical systems such as fluid, manufacturing, robots, DC motors, stepper motors, and toy trains. Some general-purpose instruments such as an oscilloscope, function generator, and multimeter are also available in the laboratory for testing and troubleshooting. All these physical systems can be controlled by computers through a suitable electronic interface. The main objective is to provide hands-on interdisciplinary mechatronics design experience to the students.
