Walmart Robots: Automating Retail Operations from Stores to Warehouses

Walmart robots refer to the various types of robotic technologies and automation the retail giant uses in its stores and distribution centers. This includes in-store shelf scanning robots, warehouse picking robots, autonomous floor cleaners, and more.

The goal of implementing these AI-enabled machines is to improve inventory management, fulfill online orders faster, free up staff time, and ultimately provide a better shopping experience. Keep reading this comprehensive guide to learn all about the different Walmart robots and how they are transforming retail.

An Overview of Robotics at Walmart

Walmart first piloted the use of in-store robots back in 2017 through a partnership with Bossa Nova Robotics. These autonomous robots continuously roamed store aisles looking for out-of-stock items, incorrect pricing, and other inventory issues.

While the Bossa Nova relationship ended in 2020, Walmart continues to expand automation, especially in its supply chain. Robotic systems can assemble online grocery orders and process customer pickups at speeds difficult for human workers to match.

According to Walmart‘s 2021 Environmental, Social & Governance Report, the company has committed $14 billion through 2024 towards automation initiatives, including warehouse robotics. This shows Walmart‘s confidence in retail automation as part of its future.

Current Robot Types Used by Walmart

Walmart employs various robots and automated technologies in different parts of its operations:

In-Store Robots

• Shelf-scanning robots: Previously provided by Bossa Nova to scan shelves and report inventory discrepancies
• Autonomous floor scrubbers: Self-driving floor cleaners free up maintenance staff time

Warehouse Automation

• Picking robots: Symbotic‘s army of robots retrieve inventory to fulfill online orders rapidly
• Storage and retrieval system: Automatically stores and locates inventory pods
• Conveyor belts: Swiftly transports picked items to consolidation stations

Other Emerging Technologies

• Pickup towers: Automated kiosks dispense online orders for pickup
• Delivery drones: Being tested to transport online grocery orders from warehouse to customerDoorstep

While in-store shelf scanning robots have been pulled, automated fulfillment technology is quickly expanding as ecommerce accelerates.

The Rise and Fall of In-Store Robots

Between 2017 and 2020, over 500 Walmart locations utilized shelf-scanning robots developed by Bossa Nova Robotics. But the program ended rather abruptly in late 2020.

How Did Store Robots Work?

These autonomous robots stood about two feet tall and used multiple cameras, sensors, and AI to navigate the store. As they roamed aisles, the robots continuously captured shelf images and compared them against an existing planogram.

Onboard computers analyzed the images in real-time. When an out of stock, incorrect price tag, or wrong item placement was detected, the robot notified associates through their handheld devices. Workers could then quickly resolve issues.

This automated monitoring system helped maintain inventory accuracy between full store audits. It also freed up staff time previously spent manually scanning shelves.

The Benefits of In-Store Robots

Here are some of the major benefits shelf-scanning store robots delivered:

• Freed up worker time from repetitive manual inventory checks
• Helped maintain real-time inventory accuracy between full audits
• Rapidly detected on-shelf availability issues to prevent stockouts
• Identified incorrect pricing labels to maintain price integrity
• Reduced out-of-stocks through faster restocking based on robot data
• Improved overall customer experience and satisfaction

According to Bossa Nova, their robots could scan up to 85% of a store‘s shelves while only needing to recharge for 20 minutes for every 12 hours of operation. This allowed continuous monitoring.

Why Were In-Store Robots Pulled?

In November 2020, Walmart ended its 4 year robotics pilot with Bossa Nova and pulled the machines out of stores. Walmart cited the need for more staff in aisles to directly deal with inventory issues rather than relying on robots.

The COVID-19 pandemic saw online shopping surge, meaning more pressure on fulfilling click-and-collect orders. Stores needed "all hands on deck", as one Walmart executive put it.

Consumer advocates had also questioned whether shoppers preferred robots over humans in stores. But during their tenure, the robots did not attract significant customer complaints.

Could Store Robots Return to Walmart?

Despite this setback, don‘t count out the possibility of seeing in-store robots return, at least overseas. In 2021, Flipkart, Walmart’s Indian e-commerce subsidiary, acquired robotics startup Bossa Nova.

Flipkart may deploy Bossa Nova‘s shelf-scanning robots in Indian stores and warehouses. This shows Walmart still believes in the technology, especially for markets with chronic labor shortages.

The Automated Warehouse: Walmart‘s Supply Chain Of The Future

While Walmart stepped back from in-store robots for now, it‘s investing heavily in warehouse automation to speed up online order fulfillment. This transformation relies on robotics providers like Symbotic.

Why Warehouse Automation Matters

Walmart‘s ecommerce sales grew 79% in 2020 alone. Online grocery orders accelerated during the pandemic as shoppers avoided stores.

To meet this digital demand, Walmart needs to modernize its regional distribution centers. Automating the supply chain allows Walmart to:

• Fulfill a high volume of online grocery orders quickly
• Offer faster delivery times to stay competitive
• Rapidly assemble store pickup orders
• Better manage inventory accuracy with robots
• Free up staff time from picking and packing

By leveraging robotics, Walmart can continue to scale up online sales and push for one-hour delivery in the near future.

How Robotized Warehouses Operate

Symbotic’s AI-powered warehouse automation combines multiple technologies:

Robots – Symbotic‘s fleet of robots can pick and move over 1,000 items per hour. The robots retrieve inventory pods from defined storage locations based on order contents.

Storage System – A 16-level automated storage structure provides extremely dense inventory storage. Robots can access any item in seconds.

Software – AI algorithms orchestrate the storage, retrieval, and consolidation of inventory. Machine learning optimizes the warehouse workflow.

Conveyors – High-speed conveyors efficiently transport inventory pods to sorting stations and consolidation points.

Workstations – Associates assemble orders from inventory pods brought by robots and conveyors. They also handle exceptions.

Together, this creates an end-to-end automated fulfillment factory. Manual processes are reduced to speed up order processing.

The Business Impact of Automation

Automating regional distribution centers results in significant business benefits:

Metric	Change from Warehouse Automation
Online order processing speed	Up to 2-3x faster
Order accuracy	99% or higher
Online grocery order capacity	2x – 3x increase
Inventory storage density	2x increase
Out-of-stocks	Lower due to inventory accuracy
Labor productivity	People handle 2-3x more orders

In initial testing, Walmart‘s pilot automated warehouse saw 800-1200 orders processed per hour, up 400% from a typical center.
