A helping (robotic) hand for the elderly

Will caring robots be welcomed by the elderly?

With ageing populations in much of the developed world, care for the elderly is a looming crisis. Many believe that the answer to a chronic shortage of human care-workers lies in breakthroughs in robotics—from robots that clean floors and help around the home, or dexterous artificial arms that can help people to bathe and dress, to humanoid companions that entertain and provide emotional support.

Robotics technology is improving to the point where robots will soon supplant the more mundane tasks of care-workers. And with the global population of over 65s set to grow 181 per cent by 2050, according to UN predictions, there will certainly be plenty of demand. The question is whether these ‘service robots’ will come soon enough to meet that demand, and whether we will welcome them when they do.

The most fertile ground for service robots is Japan, where a robot-friendly culture meets the most pronounced ageing crisis in the world.  At the forefront is manufacturing giant Toyota, which is developing a family of assistive ‘partner’ robots specifically for elderly care.

These range from single-purpose machines that can lift people to and from bed, for example, to more sophisticated multi-function robots.Toyata’s Human Support Robot is designed to help people with limited mobility around the house. It features an articulate arm and telescopic body and can recognise objects in the environment, handy for picking up a dropped pen or fetching a book from a high shelf.

Much of the underlying technology in robotics comes from the manufacturing industry, and one challenge is to give robots built for the assembly line a gentler touch. Researchers in Denmark are adapting factory arms to help people shower; others are adapting robotic limbs for more dexterous, delicate tasks such as folding clothes, cooking or doing the dishes. One sophisticated and multi-purpose bot designed for everyday environments, PR2, can fold towels and fetch a beer from the fridge – albeit very slowly, for now. 

Many of these prototypes perform well in the lab but are not yet safe enough to operate around people—let alone provide intimate care for the infirm. Some researchers, such as Accompany, a multidisciplinary consortium funded by the European Commission, are working to resolve this by designing smarter living environments in tandem with robots that are optimised to work within them.

Other robots are designed to provide emotional and social support. A Japanese-developed mechanical seal called Paro​, for example, is used to help dementia sufferers. The robot pet learns which behaviours result in more stroking, and repeats it to curry greater favour. Researchers hope that robot pets like Paro will give care-receivers a sense of empowerment by becoming care-givers themselves.

Robots that are truly aware of our emotional needs are a long way off, however. More practical applications of robotics will become viable rather sooner, as the price of the technology plummets.

Technical challenges remain. Multitasking humanoid companions will need to overcome safety concerns, and giving them the ability to operate in unfamiliar and dynamic, real-world environments is still a work in progress.

But perhaps the biggest uncertainty is whether the elderly of the future will welcome these robots into their lives.
