Robots walk, talk, pour beer and take over CES tech show

Robots that walk, talk, pour beer and play pingpong have taken over the CES gadget show in Las Vegas again. Just don't expect to find one in your home any time soon. Most home robot ventures have failed, in part because they're so difficult and expensive to design to a level of intelligence that consumers will find useful, says Bilal Zuberi, a robotics-oriented venture capitalist at Lux Capital. But that doesn't keep companies from trying. 'Roboticists, I guess, will never give up their dream to build Rosie,' says Zuberi, referring to the humanoid maid from'The Jetsons.' AvatarMind has developed service robots like iPal which is based on artificial intelligence, motion control, sensors and power management.
