It was not a good day for 16 year old Craig Hutto. On June 27, 2005, wading in crystal clear waters off a near-deserted beach 50 miles south of Panama City, Craig was attacked by an 8-foot bull shark and lost his right leg from above the knee. Today Hutto is a 6-foot 4-inch 23 year old studying Nursing at Middle Tennessee State. Fortunately for him, Nashville is also the home of Vanderbilt University where its Center for Intelligent Mechatronics has for seven years been developing an advanced prosthetic limb. They also happened to need a Lab Assistant to help them test it.
