Video: Students design special wheelchair-bicycle

Engineering students at Dulaney High School in Timonium put the finishing touches Wednesday on a special wheelchair they designed for a 9-year-old boy with cerebral palsy. For the past six months, the students have been building a therapeutic chair for Chandler Winchester. It's a wheelchair-bicycle hybrid that Chandler's family hopes will eventually be able to allow him to exercise his limbs. Chandler's family applied for the device through the Baltimore-based nonprofit V-LINC, which connects volunteer engineers with families in need. High school seniors designed the chair and built it from scratch around a car seat. The young engineers are calling it "Chandler's Chariot."
