They have bright round eyes, soft fabric bodies, and voices filled with the cheerful energy of a young child. Some wear pink dresses with braided hair, others sport neat shirts and bow ties. Yet these are not real grandchildren—they are interactive robots designed to bring companionship to older adults in South Korea, where loneliness among seniors has reached alarming levels.
A recent report in the Journal of the Korean Medical Association revealed that around ten older adults in the country lose their lives to suicide each day. While high suicide rates among the elderly are a known concern in several East Asian societies, South Korea’s numbers remain among the highest in developed nations and the most severe within OECD countries.
“We’re facing a genuine social emergency,” says Othelia E. Lee, a social work professor who studies older adults across South Korea. The country crossed into “super-aged society” status, with more than 10 million people aged 65 and above—roughly one-fifth of the population. Lee explains that this demographic shift happened so quickly that proper social support systems struggled to keep up.
The country’s rapid economic transformation reshaped family structures, moving away from multigenerational homes and traditional care norms. “Now, nearly one in three seniors lives alone,” Lee notes. Isolation, financial strain, and a sense of burden have become major contributors to depression—and ultimately suicide—among older adults.
Because public health services are stretched thin, the government has turned to technology to fill gaps in emotional support and daily monitoring. This environment paved the way for Hyodol, a care-focused AI company whose doll-like robot was created specifically for seniors spending their days alone.
Hyodol’s companion robot is a small, soft doll—usually between 15 and 20 inches—that talks, sings, encourages cognitive exercises, and responds to touch. It connects to a mobile app and a monitoring system that allows caregivers or relatives to check in on seniors remotely. Along with reminders to take medicine, the robot can alert caregivers in emergencies.
But its emotional role appears most meaningful. Users are greeted with childlike warmth as soon as they walk through the door: “Grandma, Grandpa, I’ve been waiting for you all day.” According to Hyodol CEO Jihee Kim, the intentionally adorable design builds comfort and trust, especially for seniors who may find technology intimidating.
By late 2025, more than 12,000 of these robots had been distributed through public programs, and about a thousand were purchased privately. Although the latest model carries a significant price tag, many social workers say the benefit justifies the cost.
One case described by a social worker involved an older woman who once contemplated suicide. After receiving her robot companion, she formed a strong emotional bond that eased her loneliness and reduced her sense of hopelessness.
Research supports these anecdotal findings. In a 2024 study, Lee found that seniors often named their robots, dressed them, and showed them affection—behaviors linked with reduced depression and better cognitive health. Some users even delayed the need for nursing home placement.
However, the strong attachments raise concerns. Some critics argue that the childlike design may unintentionally infantilize older adults or encourage dependence on a machine rather than real human interaction. Kim acknowledges that the robot doesn’t work for everyone—more independent seniors sometimes view it as unnecessary or irritating.
Privacy and data protection also remain topics of debate, although Hyodol states that user data is anonymized and kept secure.
Other countries are exploring different forms of companion robotics. Japan’s PARO, a therapeutic robotic seal, avoids verbal interaction altogether and acts more like a calming pet. Studies have shown its effectiveness for dementia patients, veterans, and children with developmental disorders.
With eldercare robotics projected to become a multibillion-dollar industry by 2030, South Korea’s chatty “robo-grandchild” and Japan’s comfort-focused robotic animals may be early examples of a global shift in how societies support aging populations.
