Tesco has launched a trial of a 6.5-foot-tall artificial intelligence-powered robot designed to roam supermarket aisles and identify missing stock, pricing mistakes, and misplaced items. The robot, called Tally and developed by Simbe Robotics, uses computer vision and AI to continuously monitor shelf conditions, replacing manual checks that staff previously performed.
How the Tally Robot Works
The life-sized machine autonomously navigates store aisles, scanning shelves multiple times a day. It can detect up to 10 times more out-of-stock products than manual inspections, according to Simbe. Tally also identifies pricing errors and items displayed in the wrong location, generating reports sent to store colleagues for quick resolution.
An image of the robot at a Tesco store was posted on Reddit by a user who commented: "Walked into my local Tesco to see a 'Inventory Checking' robot going about the store. Even more hilarious than it being called Tally is that nobody went within 5ft of it and kept giving it sideye."
Industry Expert Comments on the Trial
Industry expert Toby Pickard, Retail Futures Senior Partner at IGD, revealed the trial after spotting the robot in a Tesco store. He noted that this is Tesco's first deployment of autonomous shelf-scanning technology and only the second time a major UK supermarket has tested such a system.
"Rather than relying on manual audits, the robot captures shelf conditions multiple times a day and provides store teams with prioritised action lists via mobile apps and digital or printed reports," Pickard wrote on LinkedIn. "The goal is simple: resolve issues faster, improve inventory accuracy, and free up colleagues to spend more time serving customers."
Previous Trials and Global Use
Tally was first introduced a decade ago and has been used by retailers in several countries. Morrisons was the first UK supermarket to trial the robot last year at stores in Wetherby, Redcar, and Stockton. Those robots were approximately 5 feet 4 inches tall, while the Tesco trial uses a taller 6.5-foot version. During the Morrisons trial, the robot checked product placement, availability, and pricing accuracy, reducing the time staff spent on routine shelf inspections and allowing them to focus on customer assistance.
