At only 16, Blaise Awa Chi is already an accomplished engineer. The young prodigy of robotic technology, who had a traumatic childhood in rural Cameroon, has since moved to the country's economic capital of Douala, where he is following his passion for robotics, building bulldozers and graders, along with small aircraft. The resulting prototypes are made of cardboard, plywood, and other available materials, which are battery powered and operated by remote control.
