With absolutely no training or outside guidance, 15-year-old Prasant Kumar Gupta surprised everyone by making a robot, assembling electronic and video game parts packaged in a plywood box. Gupta was so inspired by a robot made by college student Diwakar Jha that he decided to make his own. So with Rs 2,000 to buy all the parts, Gupta made his robot in just 30 days. His robot can shake its thumb, move its eyes, rotate its head and walk backwards and forwards. The robot, which operates on both battery and electricity, can also count people visiting Gupta's home, switch lights on and can even launch its rocket when someone enters the house. "I can build a more efficient and sophisticated robot if I had more money," says Gupta who comes from a middle-class family in Kadamchok of Janakpur. "Ever since he was a child, he was always interested in making something or the other," says his father Suresh Kumar Gupta, who assembles projectors, torches, alarms and other electronic goods for a living. A grade 10 student, Gupta wants to study science and engineering when he finishes high school.
