Robots, once the exclusive stars of science fiction tales like “Terminator,” “R2D2,” and “Blade Runner,” are steadily transitioning from fantasy to reality. These mechanical marvels, which once seemed far-fetched, are now stepping off the screen and into our everyday lives.

This shift is underscored by a recent announcement from the American company Micropolis. They revealed the completion of two cutting-edge robotic patrol units intended for use by the Dubai police force. This marks a significant milestone in the integration of advanced technology in law enforcement.

Engineered for open-road operations, these robotic units boast impressive capabilities. They can reach speeds of up to 47 kilometers per hour and are equipped with facial recognition systems and license plate reading technologies. These features enable them to track suspects and navigate autonomously, offering a glimpse into the future of policing.

In a parallel development, Elon Musk recently shared intriguing footage on X, showcasing Tesla’s Optimus robot. In the clip, Optimus practices Kung Fu alongside a human, executing the martial arts moves with remarkable precision and timing.

While the practical applications of a Kung Fu-capable robot may be limited, the demonstration highlights the rapid advancements in robotic technology. It signals a growing array of potential uses that extend beyond traditional roles, hinting at a future where robots play an increasingly diverse role in society.

While the potential applications of Kung Fu fighting abilities are somewhat limited, the advancement in the sector over recent years demonstrates an expanding number of use cases for robot technology.

Already, robotics is used in manufacturing and healthcare, and the technology has even been deployed in combat in Ukraine.

Experts say the number of applications will inevitably grow, while becoming increasingly cost effective. 

So should investors be looking to include firms making robots in their portfolios? 

Robots could replace human labour 

It is a controversial idea, but one of the most obvious applications for humanoid robots is to do work that was previously done by humans – either more cheaply or more effectively.  

Julian Cook, portfolio specialist at T. Rowe Price Global Technology Fund, says: ‘They’re designed to replace human labour at lower cost, and as reliability and uptime improve, they could reduce wage pressures and operating costs across industries.’

Critical electrical components such as sensors and batteries have become more powerful and cheaper to produce.

Meanwhile, significant development in the AI sector over the past few years has enabled companies to build robots that can learn and adapt to new tasks, and operate more independently of human control.

YT Boon, fund manager and head of thematic at investment manager Neuberger Berman, says robots could eventually become a form of ‘physical AI’. 

‘Robotics is rapidly emerging as a transformative application of artificial intelligence in the physical world, enabling automation with intelligence,’ he says. 

‘This new wave of innovation is not just about mechanisation, but about machines that can perceive, reason, and adapt to complex environments.’

This means they could be well-suited to work on factory production lines, parcel delivery warehouses and perhaps even in shops on the high street. 

‘With advances in sensors, computer vision, and deep learning, physical AI is increasingly able to execute intricate tasks previously reserved for skilled human labour, paving the way for smarter factories, logistics hubs, and even service industries to be disrupted,’ Boon says. 

‘By automating labour-intensive processes and reducing dependency on human labour, robotics can lower unit costs, suppress wage inflation in repetitive roles, and increase economic capacity, though this may also result in greater demand for robotics enabled skills and technologies.’

Money maker: Tesla boss Elon Musk recently said he expects that Tesla’s Optimus will eventually be responsible for as much as 80 per cent of the company’s revenue

Tesla boss Elon Musk recently said he expects that Tesla’s Optimus will eventually be responsible for as much as 80 per cent of the company’s revenue.

He claims Tesla will build between 500,000 and one million robots by the end of 2027.

Cook said: ‘While that’s a long-term vision, humanoid robots are already moving from lab demos to pilot programs. Early use will focus on simple, repetitive tasks in semi-structured environments like machine tending and material handling.

‘Broader deployment will take years, but if Tesla shows real productivity gains and adoption, markets could start pricing in Optimus’s value within the next few years.’

Who to invest in if you want to back robotics 

Aside from Tesla, other Silicon Valley giants are also throwing their weight behind robotics. 

Nvidia recently launched a new chip, Jetson AGX Thor, which can be installed into robots as a ‘robot brain’.

Boon said Nvidia is ‘at the forefront of physical AI, providing the computational backbone for intelligent robots globally’.

Google’s Deepmind has been flirting with robotics too, rolling out new vision-language models in September that it says will enable develops to build robots that can solve complex multi-step tasks.

Dan Coatsworth, head of markets at AJ Bell, says: ‘We could be on the cusp of a new phase for the robotics industry where advancements in AI lead to more sophisticated capabilities for machines.

‘If technological capabilities improve and costs come down, it’s plausible that we could see a sharp rise in companies using robotics. That’s a compelling narrative for investors looking to play a specific theme.’

China is aiming to be a ‘global robotics powerhouse’ according to Boon, with the likes of Unitree and UBTech leading the sector and with more than half of the world’s humanoid robotics firms based in country.

Cook adds: ‘Chinese firms are advancing quickly in humanoids, Robots, and mobile robots, helped by cost and supply chain advantages, though top-tier software and reliability still favour US and Japanese companies.’

In October, Japanese investment giant Softbank agreed to buy the robotics arm of Swiss firm ABB for $5.4billion as it pushes to take a hold in the sector.

ABB, alongside others like Siemens, are ‘benefitting from better AI, cheaper components, and faster integration,’ Cook said.

European players, Cook adds, are more focused on service, research and remote operation. 

‘Only a few are aiming for large-scale industrial use like Tesla or leading Chinese players,’ he says. ‘Overall, Europe’s role in factory-focused humanoid robotics is still limited.’
