Robotic Gadgets Are Becoming Within Reach of Average Consumer

Since the 1960s, robots have assumed major roles in industrial manufacturing and assembly, the remote detonation of explosives, search and rescue, and academic research. But the devices have remained out of reach, in affordability and practicality, to most consumers. That, according to Professor Andrew Ng, the director of the Artificial Intelligence Lab at Stanford University in California, is about to change. One big reason, Mr. Ng said, is the mass production of smartphones and game consoles, which has driven down the size and price of robotic building blocks like accelerometers, gyroscopes and sensors. On the edges of consumer consciousness, the first generation of devices with rudimentary artificial intelligence are beginning to appear: entertainment and educational robots like the Hexy, and a line of tireless household drones that can mow lawns, sweep floors, clean swimming pools and even enhance golf games.
