Here come 'smart stores' with robots, interactive shelves

Tomorrow's retail stores want to take a page from their online rivals by embracing advanced technology -- everything from helpful robots to interactive mirrors to shelves embedded with sensors. The goal: Use these real-world store features to lure shoppers back from the internet, and maybe even nudge them to spend more in the process. Amazon's new experimental grocery store in Seattle, opening in early 2017, will let shoppers buy goods without needing to stop at a checkout line. This photo provided by SoftBank Robotics America demonstrates a shopping experience with SoftBank Robotics' humanoid robot called Pepper, waving at right. The robot can greet shoppers and has the potential to send messages geared to people¿s age and gender through facial recognition.
