Small, soft-bodied, and cheerful, these robotic companions look like children, with bright eyes, friendly voices, and playful outfits. Some wear pink dresses with braids; others sport shirts and bow ties. But these are not real grandchildren—they are AI-powered robots created to bring comfort and companionship to South Korea’s aging population.
The need is urgent. A recent study reported that around ten older adults die by suicide in South Korea each day. The country consistently records some of the highest elderly suicide rates among developed nations, raising concern among public health officials.
A RAPIDLY AGING SOCIETY
South Korea is considered a “super-aged” society, with over 10 million people aged 65 and older—about 20% of the population. The speed of this demographic change has outpaced the development of social and pension support systems. Traditional family structures have shifted, leaving many seniors living alone, isolated, and financially strained.
Professor Othelia E. Lee, a social work researcher, explains, “One in three elderly South Koreans now lives alone. Isolation, loneliness, and feeling like a burden contribute to depression and a higher risk of suicide.”
TECHNOLOGY STEPS IN
To help fill the gap in eldercare, South Korea has increasingly turned to technology. Companies like Hyodol have introduced doll-like AI robots for seniors living independently. These robots connect to mobile apps and web-based monitoring systems, allowing family members and caregivers to check in remotely.
Beyond practical assistance—like medication reminders and emergency alerts—these robots provide emotional support. They respond to touch, carry on conversations, play music, and encourage cognitive activities. The simple act of greeting a returning senior with “Grandma/Grandpa, I’ve been waiting for you all day” can have a profound emotional impact.
BUILDING BONDS THROUGH DESIGN
Hyodol CEO Jihee Kim highlights that the dolls’ baby-like appearance makes them approachable and helps seniors form bonds, even if they are not tech-savvy. By late 2025, more than 12,000 robots had been distributed through government programs, with additional units purchased privately.
Research shows that interaction with these robots can reduce depression, improve cognitive function, and even delay the need for nursing home care. Many seniors give their robots names, dress them, and show them affection, strengthening the emotional connection.
ETHICAL CONSIDERATIONS
Despite the benefits, experts caution about over-reliance and potential infantilization. Some seniors may prefer human interaction or feel uncomfortable with the monitoring aspect. Hyodol emphasizes that these robots are meant to supplement, not replace, human care. Privacy measures are in place, with anonymized data and secure voice recordings.
GLOBAL CONTEXT
Similar technologies exist worldwide. Japan’s PARO, a robotic baby seal, offers nonverbal companionship for seniors and those with cognitive challenges. Studies show it helps reduce anxiety, depression, and agitation without verbal interaction, offering a safe alternative for sensitive users.
With the eldercare robotics market projected to reach $7.7 billion by 2030, AI companions—whether chatty “grandchildren” or soothing plush robots—are emerging as innovative solutions to support aging populations around the globe.
