Research summary
What the record says.
Paro is a robotic harp seal pup developed by Takanori Shibata at Japan's AIST, in continuous production since the mid-2000s and in clinical use worldwide. It responds to touch, voice and light with movement and seal sounds, and is used in dementia care to reduce agitation and support engagement, filling the role of animal therapy where live animals are impractical.
It is the most-studied companion robot ever made, with more than 30 peer-reviewed studies, and was classified as a Class II medical device by the US FDA in 2009. A unit costs around $6,100, with leasing around $169 per month through distributors; the eighth-generation design changed little because it did not need to.
Paro chose a seal deliberately: unfamiliar enough that users hold no expectations a robot would fail to meet. Twenty years later, the entire companion-robot industry is still relearning that lesson.
