Walmart recently unveiled its Alphabot robotic system, an automated system that is set to revolutionize grocery order fulfillment by enabling quicker, more efficient order picking. Operating inside a 20,000-square-foot warehouse-style space, Alphabot uses autonomous carts to retrieve ambient, refrigerated, and frozen items ordered online for grocery pickup. After it retrieves the items, Alphabot delivers the products to a workstation, where a Walmart associate checks, bags, and delivers the final order.

Alphabot merges e-commerce and brick and mortar methods of serving customers, and it may be a harbinger of things to come. “By assembling and delivering orders to associates, Alphabot is streamlining the order process, allowing associates to do their jobs with greater speed and efficiency,” said Brian Roth, Walmart’s senior manager of pickup automation and digital operations, in a company press release. “Ultimately, this will lower dispense times, increase accuracy, and improve the entirety of online grocery. And it will help free associates to focus on service and selling, while the technology handles the more mundane, repeatable tasks.”

As customers continue to demand e-commerce options, the online grocery order business is expected to continue growing—and automated technologies, such as Alphabot, will help grocers keep up. For example, according to recent research from McKinsey, retailers are experiencing increasing margin pressure as a result of intense competition and investments in e-commerce. Typically, grocery retailers are facing 100–150 basis points of margin pressure.

“While cost pressures are not new, many retailers have already exhausted traditional cost-reduction levers,” wrote the McKinsey researchers. “Unable to pass on costs to their customers in this hypercompetitive environment, retailers are using automation to support and bolster margins.”

Generally, automation technologies are available to close the gap, but most grocery retailers are not ready to deploy all the technologies that could improve their margins. McKinsey researchers’ assessment of available automation technologies shows that a typical grocery store could already operate with up to 55%–65% fewer staff-hours. Those technologies include electronic shelf-edge labels, self-checkout terminals, shelf-scanning robots, and partially automated backroom unloading.

Few food retailers are prepared to completely overhaul their business models to accommodate available technologies, but many, like Walmart, are taking steps toward increased automation. For instance, in 2018, Kroger partnered with Microsoft to launch Kroger Edge, digital shelves that display prices, nutrition facts, coupons, and video ads, which can all be updated from a central source using Microsoft’s cloud computing service Azure. The plan is to eventually link the shelves to shoppers’ smartphones to allow for more personalization.

And Amazon now operates 25 of its Amazon Go stores, which use computer vision, sensor fusion, and deep learning technologies to allow customers to truly “grab and go,” with no checkout lines or cashiers. The technology automatically detects when products are taken from or returned to the shelves and keeps track of them in each shopper’s virtual cart. Shoppers’ Amazon accounts are charged for purchases when they exit the store.

As consumers continue to shift to online grocery ordering and other quick, convenient methods of food shopping, grocery retailers are expected to continue shifting their business models to include more automated technologies.
