Abstract: This talk aims to illustrate the creativity, challenge, technical depth and professional enjoyment associated with the invention and design of mechatronic devices. Example systems include a maglev transportation system, a guided-catheter system, an oxygen concentrator, maglev artificial hearts, high-speed switching mechanisms including an electronic engine valve, an energy storage system, and "blue-sky" ideas such as electromagnetic launch. While modeling, control and optimization are essential ingredients in mechatronic systems, the large design and application spaces of mechatronic systems compel us to place a high value on innovation at the level of system architectures - this point is illustrated throughout the talk.
