20-year-old Mpho Makutu picks scrap metal, wires and card boxes from Johannesburg’s dump sites to build remote-controlled cars and battery-powered robots and cranes. He displays his inventions in the streets of Soweto where tourists pay to see how they work.
His most recent invention is a red battery-powered robot that grabs objects and moves them around at the touch of seven different wire levers. It took him two weeks to build the robot from cardboard boxes‚ wires and scrap metal he picked from dump sites
Robots are also used to mine gold in South Africa
