Walmart filed a patent for an autonomous...shopping cart. The self-driving robo-cart will have a retro-fitted 'Roomba-like' robot drive module under their standard shopping carts. Customers can summon a WalMart robo-cart with their smartphones and follow the customers as they go through the aisles. Unattended carts in the aisles or parking lots can be brought back to a collection area. Most importantly, the carts will be equipped with sensors, microphones, speakers and video cameras to assist the shopper and it is obviously building a data-load of customer store traffic patterns and shopping preferences. Maybe I'll ask it what tasty family meals can I make for $29.86...
