There could be a future where robots will do most of your grocery shopping for you. And for some Walmart shoppers, that future is getting even closer.

Walmart (WMT), the world’s largest seller of groceries, will begin piloting a robotics system for its fast-growing online grocery pickup (OGP) service in one of its stores. The retailer has teamed up with Massachusetts-based Alert Innovation to deploy its Alphabot, a first-of-its-kind technology, in its supercenter store in Salem, New Hampshire just off of Interstate 93.

“This is about the evolution of retail,” Alert Innovation CEO John Lert told Yahoo Finance. “So, we believe that this really marks the dawn of a new era and in which robots are going to increasingly pick orders for customers and relieve them of that burden.”

Alphabot automates specific steps of the online grocery pickup process by using autonomous mobile carts to gather shelf-stable, refrigerated, and frozen items from a high-density storage system. Alphabot’s robotic carts retrieve and deliver these items to store associates to quickly fulfill online orders. What’s more, all of this happens at the back of the store, out of the view of customers.

An inventor, who as one person put it is the “Walt Disney of retail,” Lert has envisioned a supermarket that would deploy robots for more than 24 years, well before the rise of e-commerce.

“My passion was trying to figure out how to automate a supermarket,” he said.

He explained that while there’s value in shopping for fresh items like peaches and steak, pacing grocery store aisles for packaged goods is a “chore” for the customer who is essentially an “unpaid warehouse worker filling their own orders.”

Alphabot is supposed to make the job of the customer and the associate easier. Its aim is to allow associates to complete more orders faster than they would by simply walking up and down the aisles in search of goods. It also frees up time for associates to carefully select fresh produce and meat while the robots do the other work behind the scenes. For the customer, it saves time and keeps prices low.

In the last few years, Walmart has made a significant push in the online grocery pickup space. Presently, the service is available in 1,800 stores with plans to expand to more than 2,000 by the end of this year. On October 1, the Salem store will have the online grocery pickup and soon after the first-ever Alphabot technology.

One of the issues facing retail today is how to combine brick-and-mortar retail with e-commerce in a seamless experience.

Walmart, known for its “everyday low prices,” pays associates to pick and pack orders placed online. Alphabot is designed to make that process more efficient and cost-effective and improve the job for the associate.
