"STRONG", "tough" and "battle-ready" are some of the words often used to describe robots. But Sega Toys, a Japanese firm, breaks that stereotype with a "female" robot that's sweet and interactive. Using her infrared sensors and battery power, the 38cm tall robotic girlfriend named "EMA" blows kisses at nearby human heads. Like a real girlfriend, EMA can also hand out business cards, sing and dance. Sega plans to launch it in September for around $175.
