NEW YORK (CBSDFW.COM/AP) — Mechanical workers will soon be ‘on the clock’ at Texas Walmart locations. The company says it is enlisting the help of robots to keep up with their ever increasing number of online orders.

The company said it plans to build warehouses at its stores where self-driving robots will gather groceries and have them ready for shoppers to pick up in an hour or less.

Walmart declined to say how many of the warehouses it will build, but construction has started at North Texas stores in Lewisville and Plano. Building is also underway at locations in American Fork, Utah and Bentonville, Arkansas — where Walmart’s corporate offices are based. A test site was opened more than a year ago at a store in Salem, New Hampshire.

Walmart hopes the warehouses will speed up curbside pickups, where orders are brought outside to shoppers’ cars. Both options became increasingly popular as virus-weary shoppers avoid going inside stores. At the start of the pandemic last year, Walmart said delivery and pickup sales grew 300%.

The company said the robots won’t roam store aisles. Instead, they’ll stay inside warehouses built in separate areas, either within a store or next to it. Windows will be placed at some locations so shoppers can watch the robots work.

The wheeled robots carry crates of apple juice, cereal and other small goods to Walmart workers, who then bag them for shoppers. Rival Amazon uses similar technology in its warehouses, with robots bringing books, vitamins and other small items to workers to box and ship.

Walmart said the robots save time since employees don’t have to walk store aisles to find items. Workers will, however, have to go into the store to pick out fresh groceries, such as meat, fish and vegetables. They’ll also have to grab TVs, vacuum cleaners and other large items that are too large for the robots to carry.
