The Robots of Walmart

Walmart is testing free-roaming robots at 50 of its stores.  The six-foot robots roam the aisles at top speeds of three miles per hour, scanning shelves and checking price tags.  They use radar and cameras to see what needs to be restocked, and can scan the aisle in a fraction of the time it would take a human. 

So that means robots will be replacing human workers??

The company says "This new shelf-scanning technology frees up time for our associates to focus on what they tell us are the most important and exciting parts of working at Walmart – serving customers and selling merchandise."

Not everyone is buying the idea that human workers are not being replaced--
