Increasingly, the journey starts with a squat silver floor robot gliding beneath a storage rack, lifting a shelf and carrying it across a warehouse to a waiting worker.

At Geek+'s factory in the eastern Chinese city of Hefei, which the BBC visited, fleets of the robots are built and tested before being shipped to warehouses around the world.

Some of Britain's biggest retailers – including Tesco, Asda and Next – now use the company's technology.

By automating these repetitive journeys, Geek+ says retailers can increase picking speeds, store more goods in spaces that are hard to reach for humans, and reduce errors.

Unlike traditional warehouse automation, which relies on fixed conveyor systems and permanent infrastructure, autonomous mobile robots can be deployed simply using QR code floor markers and safety fencing.

Geek+, which listed in Hong Kong last year in one of the biggest robotics share sales of 2025, has become the world's largest supplier of autonomous mobile robots.

The UK has struggled with weak productivity growth for more than a decade, and economists say wider adoption of robotics will be essential if businesses are to become more efficient.

In its 2026 report SME Technology Adoption in the United Kingdom, the Organisation for Economic Co-operation and Development (OECD) said technologies like robotics would be key to improving productivity.

According to the OECD, Britain's low adoption of robotics is "surprising" given its manufacturing heritage, noting that while UK firms have embraced mature digital technologies, they lag behind in robotics and automation.

That presents an opportunity for companies such as Geek+. The UK has one of Europe's largest e-commerce and logistics sectors, but many warehouses are still in the early stages of automation.

Britain has already become Geek+'s biggest European market, with UK partner MotionTech deploying more than 2,000 robots across 10 warehouse sites.

"Customers want fast deployable solutions," says Barry Pemberton, Account Director at MotionTech. "They want high volume, high storage, fast picking… ultimately on a smaller footprint with a reduced headcount."

"We seem to have a very big shortage of labour in the UK at the moment. These technologies are really important to keep businesses thriving and meet demand."

The Trades Union Congress (TUC), which represents almost 6 million UK workers, says robotics should be used to raise productivity and improve jobs, rather than simply cut labour costs.

In its response to the government's consultation on a new AI and innovation strategy, it urged ministers to ensure workers are involved in decisions about automation and that employers invest in retraining.

"Working with technologists, workers and unions can help steer the UK's research and innovation towards workers' priorities for automation… avoiding job-cutting, low-productivity automation," the TUC said in its report.

Robotics has become a strategic priority for Beijing under President Xi Jinping's drive to develop what he calls "new quality productive forces".

With China's working-age population shrinking, policymakers increasingly see automation as essential to boosting productivity and maintaining the country's manufacturing advantage.

"The robotics story builds directly on China's electric vehicle ecosystem," says Kyle Chan, a researcher at the Brookings Institution.

Batteries, electric motors, cameras, sensors and semiconductors developed for electric vehicles (EVs) are increasingly being used across China's robotics sector, creating what he describes as "overlapping industrial ecosystems".

One company leading that crossover is Chinese EV maker XPeng, which unveiled its humanoid robot, Iron, last year.

Founder He Xiaopeng says he no longer sees XPeng simply as a carmaker.

"We want XPeng to be a high-tech company," he told the BBC. "In the future, any car company will transform into a car and robotics company."

Analysts say China's robotics push could follow a similar path as its global EV success, with local players using manufacturing prowess, dense supplier networks and rapid product development to establish an early lead.

"China is deliberately trying to build on some of those strengths," says Chan. "As it reaches into new areas, from humanoid robots to industrial robots to delivery robots."

Tesla is pursuing a similar vision with its Optimus robot, which Elon Musk has said could eventually become a bigger business than carmaking.

But China's ambitions to dominate the global robotics industry was dealt a blow this week when the US banned the import of new foreign-made advanced robots, citing national security.

The Chinese embassy in Washington responded to the move by saying that Beijing has long opposed the US' "politicising" of trade issues and sanctions based on "groundless pretexts".

The Chinese-made robots now operating in British warehouses are designed to solve the problem of moving goods. Geek+ says the company's next goal is to automate everything else.

"We are working on… end-to-end unmanned warehouse solutions," says Yanyu Liu, head of communications at Geek+.

That means automating picking, handling and eventually packing goods.

Across China, companies including AgiBot and Unitree are investing billions in humanoid robots.

But the business case for humanoids is less clear than it is for today's warehouse robots. If wheeled robots move goods cheaply, reliably and efficiently or robots with just arms can do the other automated tasks, what problem does a humanoid solve?

Developers say factories, hospitals and offices have all been designed around people, and so they may eventually be able to work in different environments without the need to redesign workplaces around automation.

But experts and developers alike agree that the current technology is not yet suitable for some repetitive tasks that require more dexterity.

"I don't think [humanoids] will change the landscape of the types of technology or the automation that's going to be put into place," says Pemberton. "They're definitely going to be complementary."

Chinese companies already account for the vast majority of global humanoid deployments, but it may be years before they are commonplace in warehouses.

For Britain, where productivity pressures and labour shortages are driving demand for automation, the country's warehouses are becoming an early testing ground for China's next major technology export.
