care & love
In a small clinic in rural Kenya, 68-year-old Amina sits on a worn wooden chair, her legs swollen from arthritis. Her daughter, Fatima, a single mother of three, bends to adjust Amina's position, wincing as her back strains under the effort. "I can't afford to take time off work," Fatima says quietly, "but if I don't help her move, she gets bedsores. And the clinic only has one nurse for 50 patients." This scene is far from unique. Across low-income countries, aging populations are colliding with strained healthcare systems, leaving millions of elderly people and their caregivers struggling to meet basic needs. But there's a glimmer of hope: robots designed for elderly care are emerging as silent partners, easing burdens and restoring dignity—if they can be made accessible.
By 2050, over 80% of the world's elderly population will live in low- and middle-income countries, according to the World Health Organization. Yet, these regions often lack even basic resources: nursing homes are rare, home care services are scarce, and healthcare workers are overstretched. In Bangladesh, for example, there's just 1 doctor for every 2,000 people, and elderly care is often left to untrained family members. This gap isn't just about medical care—it's about daily survival: helping an elderly person stand, preventing bedsores, or simply transferring them from a bed to a wheelchair without injuring either the caregiver or the patient.
Enter robots. Not the futuristic androids of science fiction, but practical, affordable tools designed to augment human care. From exoskeletons that help lift legs to electric beds that adjust with the push of a button, these technologies are quietly transforming how elderly care is delivered in resource-poor settings. Let's explore three game-changing innovations: lower limb exoskeletons, electric nursing beds, and patient lifts—and how they're making a difference where it's needed most.
For many elderly people in low-income countries, losing the ability to walk isn't just a loss of independence—it's a loss of connection. Maria, 72, in rural Peru, stopped attending her weekly church gatherings after a fall left her with limited mobility. "I felt like a burden," she recalls. "My granddaughter had to carry me everywhere, and she's only 12." But everything changed when her local clinic received a donated lower limb exoskeleton—a lightweight, wearable device that supports the legs and helps users stand and walk.
Lower limb exoskeletons are often associated with high-tech hospitals, but a new generation of simpler, more affordable models is emerging. These devices, sometimes called "wearable robots-exoskeletons lower limb," use basic motors and sensors to assist with movement, reducing the strain on weakened muscles. Unlike their expensive counterparts, many are designed for daily use, not just rehabilitation. For example, some models weigh as little as 5 kg and can be adjusted without specialized tools, making them ideal for home or community settings.
The impact goes beyond physical mobility. Studies in India and Tanzania have shown that elderly users of exoskeletons report lower rates of depression and higher self-esteem. "I can visit my neighbor again," Maria says, smiling. "And my granddaughter doesn't have to miss school to help me." For caregivers, too, exoskeletons reduce the risk of back injuries—a common problem when assisting with walking or standing. In a survey of Kenyan home caregivers, 80% reported pain from lifting or supporting elderly relatives; those using exoskeletons saw a 50% reduction in discomfort.
Of course, cost remains a barrier. A high-end exoskeleton can cost $50,000 or more, but "oem" (original equipment manufacturer) models—produced by companies that specialize in affordable, customizable devices—are changing that. Some Chinese and Indian manufacturers now offer basic exoskeletons for under $5,000, and local assembly partnerships are bringing prices down further. In Vietnam, a nonprofit has partnered with a local factory to produce exoskeletons using recycled materials, cutting costs by 40%.
In a crowded hospital ward in Nigeria, Nurse Aisha bends over a patient, manually cranking a rusted bed to adjust its height. "This bed is 20 years old," she says, wiping sweat from her brow. "It takes two people to move it, and it still gets stuck. Half the time, we can't even raise the head high enough for patients to eat." For elderly patients confined to bed, this isn't just inconvenient—it's dangerous. Manual beds make it hard to reposition patients, increasing the risk of pressure ulcers (bedsores), which affect up to 30% of bedridden elderly in low-income countries.
Electric nursing beds are a game-changer here. These beds, which adjust with the push of a button, allow caregivers to easily raise the head, feet, or height of the bed—reducing strain and improving patient comfort. "With an electric bed, I can reposition a patient in 30 seconds alone," says Nurse Aisha, who now works at a clinic with two new electric beds. "Patients can sit up to eat, which means fewer cases of aspiration pneumonia. And the beds have pressure-relief mattresses—we've seen pressure ulcers ｄｒｏｐ by 60%."
The "electric nursing bed market" has grown rapidly in recent years, with manufacturers in China, India, and Malaysia producing models tailored to low-resource settings. These beds often skip fancy features (like built-in scales) in favor of durability and low power consumption—some run on rechargeable batteries, ideal for areas with unreliable electricity. "We prioritize 'multifunction' without complexity," explains a representative from a Chinese manufacturer. "Our basic model has three motors for adjusting positions, but it's simple to repair and uses parts available locally."
For home care, "portable nursing bed" options are also gaining popularity. These lightweight, foldable beds can be used in small living spaces and are easier to transport than traditional models. In the Philippines, a community health program distributes portable electric beds to families caring for elderly relatives at home, reducing hospital readmissions by 45%. "My mother can sleep comfortably now, and I don't have to quit my job to care for her," says a daughter in Manila.
Transferring an elderly person from a bed to a wheelchair is one of the most dangerous tasks for caregivers. In Ghana, 70% of home caregivers report back injuries from lifting, and many are forced to stop working as a result. "I herniated a disc helping my father into the shower," says Kwame, a 35-year-old caregiver. "After that, I couldn't lift him at all. We had to hire someone, but we could barely afford it."
"Patient lift assist" devices solve this problem. These tools—ranging from simple slings to motorized hoists—allow one caregiver to safely transfer a patient with minimal effort. Ceiling-mounted lifts are ideal for hospitals, but portable models (some weighing as little as 15 kg) work well in homes. "I can now transfer my father by myself," Kwame says, using a portable lift donated by a local charity. "It's not just easier for me—it's better for him. He doesn't feel like he's being 'moved'; he's part of the process."
Patient lifts also protect patients from falls. In a study of nursing homes in Brazil, facilities using lifts saw a 75% reduction in patient falls during transfers. For elderly people with limited mobility, this means fewer fractures and hospital stays. "Falls are the leading cause of injury-related deaths in the elderly," says a public health expert in Tanzania. "Patient lifts aren't just about convenience—they're life-saving."

Despite their benefits, robots in elderly care face significant challenges in low-income countries. Cost is the biggest barrier: even affordable models can be out of reach for individual families or underfunded clinics. Maintenance is another issue—spare parts and technical support are often scarce. And training is critical: caregivers need to learn how to use these devices safely, which requires time and resources.
But solutions are emerging. Governments in Kenya and Colombia have launched subsidy programs for assistive technologies, covering up to 70% of the cost for low-income families. Community "tech hubs" in India and Senegal train caregivers to use and repair devices, turning local residents into "robot champions." And partnerships between NGOs and manufacturers are driving innovation: one collaboration between a U.S. nonprofit and a Chinese factory resulted in a $1,500 patient lift designed specifically for rural clinics.
There's also a growing focus on "appropriate technology"—devices that are simple, durable, and culturally sensitive. For example, some exoskeletons now come with locally designed harnesses to fit traditional clothing, and electric beds are painted in bright colors to align with cultural preferences for vibrant home environments. "Technology shouldn't feel foreign," says a designer from a Kenyan tech startup. "It should feel like an extension of the care already happening."
Robots will never ｒｅｐｌａｃｅ the human touch in elderly care—but they can amplify it. In the villages of Tanzania, in the slums of Manila, and in the rural clinics of Peru, these technologies are already helping caregivers provide better care, and elderly people live with more dignity. They're not just tools—they're partners in a mission to ensure that growing old doesn't mean being forgotten.
As Nurse Aisha puts it: "These beds and lifts don't take away my job—they let me do it better. I can spend less time cranking beds and more time talking to my patients, holding their hands, and making them feel loved." And for Maria, the Peruvian grandmother who now walks to church again: "The exoskeleton gave me my legs back. But more than that, it gave me my life back."
The road ahead isn't easy, but with innovation, collaboration, and a focus on people, robots could be the key to ensuring that every elderly person—no matter where they live—gets the care and respect they deserve.
