Back To Cuddly Robots


Our pets give us unwavering support and at times of pressure or stress help to lower our cortisol levels. Of course, there are other times when they get into something that they’re not supposed to that they add to our stress levels, but by and large, companion animals are good for us and are recommended to improve our quality of life as we age.

It is not always possible to have our own cat or dog so what are we going to do? We can of course talk to the passing dogs as they are being walked. Mostly they appreciate the attention, but not always. Anyway, these brief encounters are no real substitute.

The alternative is the touchy-feely robot. Previous posts have talked about Paro last year. Paro is the baby Harp seal robot that comes in white (mostly) or dark gray so it doesn’t show the dirt quite so much.

Paro is a very responsive robot who likes being stroked, talked to and picked up and held. It wriggles with pleasure, flapping its flippers appreciatively and squeaking like a baby Harp seal should, bring our cortisol levels crashing with each cuddle.

 He (or maybe she, whichever you feel is appropriate) does come through the mail at quite a high price though. At close to $7k he is a more serious commitment than anything but the most successful show animal, but unlike them there is no chance of stud fees or offspring to sell off to recoup the outlay.

An article in Discovery News reports that about a 19,000 people are still living in temporary housing, which was erected in a baseball stadium in northern Japan after the tsunami that occurred about one year ago (1). Paros are being offered to help reduce depression and as replacement for drowned pets that they can’t bear to replace. There are also Paros that are available for short term loan, rather like a library book.

Perhaps we should adopt this idea and have surgeries prescribe short term Paro house guests as an alternative to antidepressant drugs. It may prove a cheaper option in the long-term.

Robot Friends


Companion robots have been with us for a few years now, although the focus has been mainly in Japan. Ifbot was a white plastic guy who could make himself useful and do things like taking photographs. He didn’t seem to be much in demand after the first few weeks in an old folks home. Perhaps R2D2-like bots are better as care-bots than in the companion role.

Animal robots seem to do better. AIBO, the dog-bot and NeCoRo, the cat-bot both seem to be hits with kids. However, the ultimate (at present) companion-bot is PARO, a baby Harp seal robot. It made top spot as the most therapeutic robot in the Guinness World Records collection.

It may be the helpless look with the big “baby” eyes, or its cries, but it always needs a hug and a stroke. It does well as a companion-bot and has worked well in some old folks homes, and now has at least 35 users in North America. Most of these users are institutions.

The numbers of people who have interacted with Paro is quite large as over 1,000 have been sold with about two thirds of these for private use, so he/she is now an establishment figure.

A survey has been conducted by Shibata et al to see how people are getting on with their companion Harp seal robot flopping around in their living space and crying for attention (1). 85 people agreed to give their responses. 61 of these were women and 22 were men and most of the owners were between 30 and 90-years old (95%).

The owners all liked to stroke and hug their robot as well as speak to him/her. The owners liked to say hello when they came home and praise Paro for responding, as well as saying “good night” or “good morning.” Many people who had kept pets previously wanted a brush and a collar to keep their Paro spruced up and well decked out.

That Paro is a cute baby animal that they can’t buy in a pet shop is probably a major part of his/her attraction compared to dog or cat-bots. Also many of the owners could not currently own a pet because of apartment living or some such constraint.

It appears that companion-bots that respond when you hug and stroke them, who look and feel cuddly, and who respond when you speak to them, are welcomed by all ages. What we need now is an fMRI study coupled with measurements of the levels of hormones such as dopamine to compare the therapeutic effectiveness of a companion animal with a companion-bot.
