WASHBURN, Tenn. — Scott Rogers, whose daily journey begins with a single step on a bionic leg, is preparing for a hike up the 2,168-mile Appalachian Trail.
"I have been told I can't do it, that I won't make it. But how do you know?" the 34-year-old says.
Rogers hikes with the help of the "C-Leg" — a prosthetic powered by a battery, driven by hydraulics and controlled by microprocessors that monitor his movement 50 times a second to create a natural, stable gait.
