Grocery store robots: common questions

Machines that do a specific job in a supermarket or convenience store without a person driving them: scanning shelves for gaps and wrong prices, cleaning floors, delivering orders, picking online orders, storing stock in an automated grid, or restocking shelves and rotating stock.^{[4][7][8][12][1]}

Walmart tested shelf-scanning robots in 50 stores from 2017 before ending the contract in 2020; Co-op and Tesco have used Starship delivery robots in Milton Keynes since 2018; grocers including Kroger, Sobeys and Coles license Ocado's automated fulfilment platform; and Seven-Eleven Japan plans to deploy Telexistence's humanoid in stores from 2029. Vendors list their current retail customers on their own sites.^{[3][9][11][10]}

Few vendors publish prices, and many sell as a monthly service rather than a purchase. Ask for the full cost in writing: hardware or subscription, installation, maintenance, software, and the staff time it needs. The economics page shows how to model payback with your own figures.

Yes, and it is the newest category. Humanoid robots from Theseus Robotics restock shelves, rotate stock and pick orders, and operators can see them in in-person private previews. Telexistence already runs a beverage restocking robot, Ghost. Most robots in stores today still only report gaps for staff to fill.^[1][2][10]

Today's grocery robots take on single, repetitive tasks: checking shelves, scrubbing floors, carrying orders, restocking. Retailers announcing robots, such as Seven-Eleven Japan, describe the aim as covering labour shortages and freeing staff for work only people can do. What it means for your staff depends on how you redeploy the hours; ask any vendor how its customers did it.^[10]

The one where a robot both finds and fixes the problem. Shelf checks are the most automated job today, but the value only lands when the gap is filled, so restocking and stock rotation are where most of the floor hours are. Order picking matters most if online grocery is a large share of the store's sales.^[3][1]

They are designed to slow down, stop and give way, and standards such as ISO 13482 for service robots and ISO/TS 15066 for collaborative robots set requirements for working near people. In the EU, the Machinery Regulation applies from 14 January 2027. Ask any vendor which standards its robot is certified to, and watch it work during trading hours.^[18][19][14]

Good systems alert staff and, for some robots, a remote operator takes over: Starship's delivery robots can be remote-controlled when autonomy fails. Ask who is alerted, how fast, and whether the store has to staff the fallback.^[9]

There is little independent research on it. Vendors publish their own survey figures; ask for the method behind them, and watch how shoppers react during a trial in your own store.^[4]

Any mobile robot takes aisle space. Shelf scanners move slowly through the aisles in opening hours, while many floor cleaners run when stores are quiet. Ask to see the robot at your busiest time of day.^[3]

Yes. Starship delivery robots have carried Co-op and Tesco groceries in Milton Keynes since 2018, Ocado's automated fulfilment was developed in the UK and is licensed to France's Casino, and Theseus Robotics builds humanoid restocking robots in Zürich.^[9][11][1]

The EU Machinery Regulation 2023/1230 applies from 14 January 2027 and covers machinery safety. The GDPR applies to any camera images of identifiable people. The EU AI Act sets rules on AI systems, including biometric identification.^[14][15][17]

Robots that see the shelf use cameras, and a camera in an aisle can capture people. Under the GDPR, images of identifiable people are personal data. Ask whether the robot blurs or discards people in its images, how long images are kept, and where they are stored.^[15][16]

Shelf robots are built to look at products, not faces, but ask each vendor directly. In the EU, using biometric identification is restricted under the AI Act and the GDPR.^[17][15]
