Robo-doc, dancing droids lead CES 2013 robot pack (pictures)
They'll help you get healthier, clean your floors, and entertain you. Robots take a step or two toward ubiquity at this year's Consumer Electronics Show.

Dr. Robot will see you now
Bots with a view
A $299 version will clean windows that have frames, in other words well-defined borders, while a $349 version will be able to clean glass walls or windows that have no frames.
Robot ball + Nyan Cat = bliss
Lego gets more robotic
Toss out the pool brush, toss in Mirra
An improvement on the company's previous Verro pool bots, the $1,299 Mirra can pump and filter about 70 gallons of pool water per minute and suck up debris as small as 2 microns.
Home helpers
Famibot and Minibot can perform functions like roving around and purifying the air, alerting you if there's a fire or intruder, and sending your phone a video feed of your home.
They should hit U.S. markets in the first half of 2013, with Famibot having a suggested retail price of $899, and Minibot priced at $499.
Telepresence on the cheap
Recent features include a laser pointer and the ability to use any audio/video software such as Skype to communicate with friends while rolling around in a distant location.
Robot 'Gangnam Style'
Tosy went back to work on the entertainer droid, giving it more actuators, moves by choreographer Derek Hough, and a tune to dance to -- something called "Gangnam Style," which you've probably never heard of.
The drone is back
Titanoboa slithers in
Titanoboa is 50 feet long and weighs 1,200 pounds. While it usually creeps around Burning Man, it put in an appearance at CES, slithering in right by the CNET trailer.
