Bossa Nova shelf-scanning robots

Walmart ended its shelf-scanning robot contract after finding other ways to monitor inventory

StoppedPress reportingOfficial ↗

Problem

Walmart wanted to identify empty shelves, incorrect prices and missing labels while freeing employees to serve customers. Its shelf-scanning robots used machine learning to gather inventory information.

Approach

Walmart introduced the scanners in 2016 and expanded their deployment through its partnership with Bossa Nova Robotics. By November 2020, the robots operated in about 500 stores. Retail Dive reported that employees picking online orders were walking the aisles more frequently and providing another way to identify inventory problems. Walmart ended the contract and said it would concentrate on other inventory processes and technologies.

Takeaway

The growth of online order picking changed the work already happening in Walmart's aisles. That reduced the need for a separate robot to collect inventory information.
