Walmart's new robot fleet is having an impact on stores.
The retailer has expanded its initial test of its shelf-scanning robots to 50 stores across four states, including Arkansas and California. They're shaped like six-foot-tall roving towers on wheels and are equipped with cameras that can spot shelving errors. Walmart is working with the fully autonomous robots' manufacturer, Bossa Nova Robotics, for the program.
The robots scan aisles for out-of-stock items, things that were put in the wrong place by customers, incorrect prices, and wrong or missing labels. They continuously go up and down the aisles of the store, alerting human employees to the errors it sees.
