In a quiet robotics lab in north-west London, three black mechanical hands stretch and curl with human-like precision. No claws or pincers. Just joints where they should be.
“We’re not building Terminator,” laughs Rich Walker, director of Shadow Robot, as he proudly presents his company’s latest prototypes. His vision is less sci-fi villain and more everyday assistant: robots capable of handling household chores and supporting the elderly.
That ambition ties into one of the United Kingdom’s most urgent challenges. Social care services are under immense pressure. Skills for Care reported last year that England alone faces 131,000 vacancies for adult care workers. Age UK estimates nearly two million elderly people live with unmet care needs. By 2050, one in four people in the UK is expected to be 65 or older, further straining support systems.
Governments have turned to robotics for help. A previous UK administration committed 34 million pounds to accelerate care-focused robotic innovation and predicted that autonomous systems would become part of daily life within 20 years. The question remains: can people really trust strong, autonomous machines to support vulnerable seniors?
Japan’s early lessons
Japan offers a glimpse of what the future might look like. Over the past decade, its government subsidised development of care-focused robots in response to a fast-aging population and staff shortages in care homes.
Dr James Wright, an AI specialist at Queen Mary University of London, spent months studying three robot types used in a Japanese care facility:
• HUG, a mobility robot that helps transfer people from bed to wheelchairs.
• Paro, a baby seal-like robot for dementia therapy.
• Pepper, a humanoid robot that leads exercise sessions.
Wright expected overworked carers to welcome robotic help. Instead, he found the machines became burdens. Staff spent time cleaning, charging and troubleshooting them. Pepper struggled to lead classes because residents could not see or hear it clearly. Paro distressed one resident who became overly attached. HUG was bulky and often needed moving out of the way.
Within weeks, many workers gave up using them.
Developers say the robots have since improved. But Wright’s insights underscore the complexity of introducing automation into care environments.
Designing robots older adults actually want
Experts argue that better, more adaptable machines are coming. Professor Praminda Caleb-Solly of the University of Nottingham leads Emergence, a network connecting engineers with care providers and older users.
Feedback reveals diverse preferences: friendly voices, non-threatening or cute designs, and most importantly, robots that maintain themselves.
“We don’t want to look after the robot. We want the robot to look after us,” one respondent said.
Some care providers in the UK are already testing small, voice-activated devices such as Geni. Reactions vary widely, described by one project leader as “like Marmite.” But the goal is not to replace workers. Instead, robots could handle routine tasks, freeing carers to focus on human interaction.
Building machines that move like us
Back at Shadow Robot, Walker highlights the final frontier: dexterity. Their robotic hand uses around 100 sensors and can solve a Rubik’s Cube one-handed. Still, delicate tasks such as using scissors remain out of reach.
“Amazingly, cutting with scissors involves fine touch, balance and constant feedback. Telling a robot how to do that is extremely difficult,” he says.
Walker’s company is part of the Robot Dexterity Programme, funded by the UK’s Advanced Research and Invention Agency (ARIA), to create more graceful and efficient robot movement. Scientists are even studying how animals move to redesign robot bodies from the ground up.
Artificial muscles for a gentler touch
Another innovation comes from Danish engineer-entrepreneur Guggi Kofod, whose start-up Pliantics is developing artificial muscles to replace motors in robots. His motivation is personal, driven by loved ones who faced dementia.
“If we can build systems that reduce fear and help people live with dignity, that’s incredibly motivating,” he says.
The future of care may have metal hands
While robots have a long way to go before they reliably clean homes or support frail individuals without supervision, UK researchers insist progress is accelerating. The dream remains a robot that charges itself, keeps itself tidy and steps in when human help is stretched thin.
Not a Terminator. Just a helpful hand in a country that increasingly needs one.
