Hyodol: a grandchild-shaped doll robot that local governments give to older people living alone

Hyodol is a plush doll robot shaped like a seven-year-old child. Korean local governments hand it out to older people who live alone, and more than ten thousand are in use.

A plush doll robot that looks like a grandchild

Hyodol is a doll robot made by Hyodol Co. in Anyang, Korea. Seven sensors sit inside a plush doll shaped like a seven-year-old child, so it responds when stroked on the head or held by the hand. It talks, reminds users of medication and meal times, and plays songs. If it detects no movement for 24 hours, it alerts care workers. The unit price was reported as 1.6 million won.

Spread through local government budgets

Hyodol is sold mainly to local governments rather than individuals. Pilots began in 2019 in Seoul’s Yeongdeungpo district and in Goyang. By May 2021 about 3,000 units were in use across 50 local governments, and by August 2026 more than 15,000 across more than 187. In June 2026, however, Segye Ilbo gave a figure of about 500 units across 185 local governments, far below the other counts. A user, Bang Chun-ja, told AFP: “when I’m with Hyodol, I never get hurt.”

Effects at three months, burdens in the field

A 2022 study in the Journal of Applied Gerontology followed 180 low-income older adults living alone. Depression and quality of life improved at three months, but the gains did not last to six months. Jeonnam province said depression scores in its pilot fell from 7.34 to 2.74, but that figure was not peer-reviewed. Problems in the field were reported too. A user with dementia got lost after the doll said it wanted to hear a stream, and the company removed such phrases. Reports also raised heavier workloads for care workers and privacy concerns.

Who decides what the doll says?

Hyodol is both a companion and a set of eyes for care workers. That means a single sentence from the doll can change what its user does. The case of the user who got lost shows how carefully a robot’s words must be designed when it speaks to older people.

When one sentence from a robot moves its user, who reviews that sentence?
