Walmart’s Multibillion-Dollar Automation Push Stumbles on Simple Warehouse Tasks

Core Event: Robots Falter on Basic Fulfillment Work
Walmart’s effort to replace human labor with autonomous systems is hitting operational snags. Small wheeled robots that move inventory through more than a dozen fulfillment centers cannot reliably lift oversized items such as bags of dog food, large-screen TVs, or whole turkeys. The “breakpack” step—removing products from cardboard boxes for shipment—remains difficult, forcing the retailer to keep a sizable human workforce for the task.
Background & Context
Since 2016 Walmart has invested roughly $1 billion in automated ecommerce fulfillment, acquiring and later divesting its former technology partner Alert Innovation. The company now works with robotics provider Symbotic, which bought Alert Innovation in 2023. Walmart’s automation strategy mirrors an industry-wide “arms race,” with rivals such as Amazon also pouring billions into similar initiatives.
Data & Statistics
- More than 140,000 employees work in Walmart’s U.S. warehouses.
- Five next-generation fulfillment centers are operational; a sixth in Georgia is planned, and a new 900,000-sq-ft site opened in Stockton, California.
- At Stockton, automation is expected to create over 1,000 jobs while eventually reducing overall labor needs.
- Electricity use at fully automated grocery sites has risen to about $800,000 per month, up from roughly $250,000 when operations were manual.
- Symbotic reported that fewer than 10 % of its robots required repair in the prior year, a figure that has since fallen to about 5 %.
Official Statements & Responses
Rob Montgomery, head of supply-chain operations for Walmart U.S., described the current stage as “peak complexity,” noting the company is still integrating a patchwork of robotic systems into warehouses built in the 1980s and 1990s. Symbotic indicated its new SymMicro ecommerce system should be operational within six months and then rolled out to additional locations. Walmart officials emphasized that human workers will remain essential for tasks such as trailer unloading and robot maintenance, and that the company does not anticipate large-scale layoffs because warehouse turnover is already high.
On-the-Ground Reports
Employees at a newly automated grocery warehouse in California reported that robotic arms repeatedly fumbled large frozen turkeys, requiring shipments to be rerouted. Workers at the Brooksville, Florida test site noted that roughly 80 % of inventory movement is now automated, yet the remaining 20 %—including heavy items like dog food—still relies on human handling.
Conflicting Reports & Gaps
Sources differ on the exact proportion of robots under repair: one statement cites “less than 10 %” of units needing fixes in the previous year, while a later update places the figure at “about 5 %.” No publicly available analysis quantifies the net cost impact of higher electricity use versus projected labor savings, leaving the long-term financial viability of the automation program uncertain.

What’s Next
Symbotic expects its upgraded SymMicro system to be live in roughly six months, after which additional Walmart sites may adopt the technology. The Stockton fulfillment center will begin handling a larger share of online orders, and Walmart plans to open a sixth next-generation center in Georgia later this year. The retailer continues to evaluate box redesigns and robot maintenance protocols as it works toward reducing the human labor component of its supply chain.
