American retailer Wal-Mart is rolling out shelf-scanning robots to more than 50 stores in the United States after a successful pilot scheme in Arkansas, Pennsylvania and California.

The two-foot tall robots scan shelves using cameras to identify missing and misplaced items, as well as incorrect prices and labels.

Human employees then use the data to stock shelves and fix errors more rapidly, which helps increase sales.

Wal-Mart said the robots would not replace employees, adding that humans typically only have time to scan shelves about twice a week.

“If you are running up and down the aisle and you want to decide if we are out of Cheerios or not, a human doesn’t do that job very well, and they don’t like it,” Jeremy King, chief technology officer for Walmart US and eCommerce, told Reuters.

He added that the robots are 50 per cent more productive than their human counterparts in terms of speed and accuracy.
