Dr. Robot will see you now

At CES 2013, robots ranging from cleaning droids to dancing bots to bedside medical advisers swarmed the Las Vegas Convention Center. One of the more newsworthy machines is RP-VITA, a 5-foot-tall iPad-operated robot developed by iRobot and InTouch Health. Designed to allow remote doctors to communicate with patients through the display, RP-VITA is the first navigating communications medical robot to receive FDA approval.
