U-M-Flint seniors Casey Lang, Jason Smith, Fred Vandervennet and Ethan Roelle demonstrate a baseball launcher they designed and built. The engineering students created the machine to send a variety of flies and grounders to the outfield. The launcher has a range of 400 feet and is completely computer controlled. It can send a ball anywhere on the field, and it can throw curves, sliders and fastballs when used for pitching. (Photo by Mel Serow, U-M-Flint)
