DOES EVERYTHING BUT TALK – Ready to respond to his master's directions is Robetron a sixfoot electronic 'man,' who owes his existence to the ingenuity and diligence of 13-year-old Donald Rich of Kew Gardens, Borough of Queens, New York.
Robetron, who is capable of 'seeing' with his electronic eyes and of 'sensing the presence of a human being, can pick up objects manually or magnetically and moves about on wheels powered by electric motors. Donald holds a computer he designed to fit the robot like a vest, enabling Robetron to do mathematical calculations.
