Armstrong State University’s Engineering Studies Program hosted the 2015 Engineering Design Challenge on Saturday, which showcased the ingenuity and creativity of students from Johnson High School, Beach High School, Savannah High School, Savannah Early College, Savannah Christian Preparatory School, Richmond Hill High School, Savannah Arts Academy and Jenkins High School. Each team, comprised of four to six students, designed and built a battery-powered, multi-terrain wheelchair with the assistance of a project mentor and Armstrong engineering students. The competition included a 40-meter race, a timed maneuver course, a demonstration of safety features and a design poster presentation with an engineering journal evaluation. Cameron Coates, coordinator of the engineering studies program at Armstrong, said the students started working on their projects in December.
