Walmart Inc. has ended its effort to use roving robots in store aisles to keep track of its inventory, reversing a yearslong push to automate the task with the hulking machines after finding during the coronavirus pandemic that humans can help get similar results. The retail giant has ended its contract with robotics company Bossa Nova Robotics Inc., with which it joined over the past five years to gradually add six-foot-tall inventory-scanning machines to stores.
