Apparently even Walmart is looking at automation in its stores. Two different initiatives seem to be under evaluation by Walmart.
EMMA (Enabling Mobile Machine Automation), an autonomous machine for scrubbing store floors, is under evaluation at five stores. After a training run controlled by a human operator to identify the desired operational path, the machine will autonomously clean the floor. It has built in sensors and cameras similar to autonomous vehicles currently on the roads that allow it to navigate around obstacles at a sedate 2.5 miles per hour. EMMA is a product of Brain Corp.
In a separate trial, Walmart has deployed shelf-scanning robots in 50 stores. These machines will scan store shelves to verify inventory, prices and misplaced items. These units are from Bossa Nova Robotics.
Will these attempts at automation cost jobs? Well, probably over the long term, but it is unlikely that the impact will be significant. It is clear though that robots and automation will be in our future.
