OpenSim-based Science Fair Project Wins First Place

Feb 26, 2014

Florida high school students Christopher Fregly and Brandon Kim took first place in the Physics and Astronomy category at the Alachua Regional Science Fair. Working with NASA, Fregly and Kim used the OpenSim software to predict simple ways that astronauts could modify the standard squat exercise to be more effective at maintaining muscle mass on the International Space Station. They will be going on to compete in the Florida State Science Fair in April and in the prestigious Intel International Science and Engineering Fair in May. Read more here
