PARO is a therapeutic robot baby harp seal, intended to be very cute and to have a calming effect on and elicit emotional responses in patients of hospitals and nursing homes, similar to animal-assisted therapy except using robots. History Paro was designed by Takanori Shibata of the Intelligent System Research Institute of Japan's AIST beginning in 1993. It was first exhibited to the public in late 2001, costing US$15 million to develop, and became a "Best of COMDEX" finalist in 2003, and handmade versions have been sold commercially by Shibata's company Intelligent System Co. since 2004. Paro is based on harp seals Shibata saw in an ice field in northeastern Canada, where he also recorded their cries in order to use them for Paro's simulated cries. Paro was classified as a Class 2 medical device by U.S. regulators in fall 2009. Paro has been used primarily in care facilities, especially as a form of therapy for dementia patients. After a study was conducted to see the effects of robots on children with autism spectrum disorder, it appeared that there are numerous benefits. The robots were able to analyze the specifics of the disorder and then intervened by creating controlled environments that assisted in reducing the anxiety that can result from the disorder (2016). This also benefits children as the robots are social companions for those interacting with it. The study found that as a result of the robots, “encouraging effects such as increased engagement, increased levels of attention and novel social behaviours, for example joint attention and imitation were found, when the children interact with robots” (Huijnen, 2016, p. 2010). The robots had roles of a playmate, social actor, therapist and contained the ability to behave as humans (2016). According to a study based on a 2014 census in Brazil, 195 of 250 older people living in retirement homes chose the Paro robot for nurses. A 2016 study of 130 older citizens living in Slovakian retirement homes indicated that 70 of them chose companion bots as well, according to research done by a group of mechatronic experts. It was feasible to detect agitation tendencies and intervene before patients got aggressive using Paro by modulating their sensory stimulations. Experiments at a Japanese nursing home show that dementia patients who interacted with Paro calmed down in the majority of cases without the usage of drugs. Because the robot does not need to
