Wireless-Integrated Embedded Real-Time Control: A Case Study in Adopting Resources for Development of a Low- Cost Interdisciplinary Laboratory ProjectAbstractIn the last decade, it has become apparent that the grand challenge problems of this century spandisciplines. In spite of this, engineering curricula are still strongly stovepiped, even within eachengineering discipline, and both inertia and downward budget pressures encourage curricularconservatism. At the same time, the need is urgent to expose students to the diversity andcomplexity of real-world problems where there is no “best” solution. How should we helpstudents learn across disciplines and blend disciplinary knowledge to solve problems?This paper describes a laboratory project suitable for courses in areas of control and embeddedsystems that weaves critical aspects of control systems design with real-time embedded systemshardware and software, and along the way incorporates additional skills and tools. The projectbuilds on previous efforts that have used the classic “ball-in-tube” experimental platform. Wehave developed an extremely low-cost experimental platform that student teams assemble fromsimple parts (e.g., shoeboxes and muffin fans), and that uses wireless communication betweenthe real-time platform and a personal computer that provides a human interface and analyticaltools. For real-time data acquisition and control, we adopted the CLIO platform that wasdesigned for the experiential component of MUSE, a pedagogical project to increase the abilityof students to become conversant in skills related to systems thinking. In this spirit, the projectexposes students to experimentation, modeling and design across system layers. While tacklingthe project, students also become more adept at (i) architecting distributed applications thatintegrate embedded and desktop computing systems, (ii) data acquisition, including measurementnoise and signal conditioning, (iii) actuation, including motor control, and (iv) wirelesscommunication. We present early assessment results evaluating how effectively the projecthelps students build critical systems-thinking skills, and the challenges of adopting resources forfast-tracking the development of new laboratory projects.
