Walmart to expand in-store tech, including Pickup Towers for online orders and robots

Walmart is doubling down on its technology innovations in its stores. The retailer today announced the expanded rollout of several technologies — ranging from in-store Pickup Towers to help customers quickly grab their online orders to floor-scrubbing robots. The firm plans to deploy 1,860 floor-cleaning robots by the end of 2019.

The Auto-S shelf scanners roll around aisles to scan prices and check inventory. The robots which have been tested since 2017, check inventory levels to see what needs restocking, identifying and finding misplaced items or locating incorrect prices or labeling, Tech Crunch reports.
