As a result of declining birth rates and increasing life-expectancies, populations around the world are nowadays ageing at unprecedented rates. In Europe, the life expectancy at birth for both, men and women, has increased by 10 years within the past five decades, and is expected to rise even further in the future (European Commission, 2020). While the increasing longevity brought about by significant breakthroughs in healthcare has been a major achievement of our time, the changing demographics are also posing tremendous challenges on public health care systems in providing sufficient care for the growing share of older people. Already today, the demand for workers in elderly care is significantly exceeding the supply, a trend that will continue and accelerate even further.
Major developments in AI and robotic technology however provide an exciting opportunity to complement elderly care by counteracting the growing labor shortages within nursing facilities and home care and helping older people to preserve their independence for longer (Association for Advancing Automation, 2020).
Overview of service robots in elderly care
Broadly, one can distinguish between two categories of robots in elderly care. The first category includes rehabilitation robots which aim at physical assistance and would include devices such as smart wheelchairs and artificial limbs. The second category refers to assistive social robots which are seen as “social entities” that are meant to actively interact and communicate with the user. Within this category, there are two different kinds of social robots: service type robots and companion type robots (Broekens et al., 2009).
Service type robots
Service type robots have their main functionality in assisting older people in their everyday lives. One example is the robot “Pearl” . It reminds people of their daily activities, such as eating or going to the bathroom and supports them in their mobility, for instance by navigating them through the nursing facilities and accompanying them to appointments, social events or regular walks for exercise (Pollack et al., 2002).
Companion type robots
Apart from service type robots, robots are also being utilized as “companions” that can help counteracting loneliness and strengthening the psychological well-being amongst older people. One example is the robot “Pepper” which is utilized in several care homes in the UK. “Pepper” can learn about the interests of care home residents, allowing him to have conversations with them, play their favorite music and play games with them (The Guardian, 2020). Another type of companion robots includes therapeutic pet robots, such as the cat-shaped robot “iCat” or the seal-shaped robot “Paro”. Studies have shown, that “Paro” can indeed reduce loneliness, depression, agitation and blood pressure among older adults with dementia (Hung et al., 2019).
Reflection
Personally, I think these are exciting developments. While robots can by no means sufficiently compensate for the growing labour and capacity issues in elderly care, I do think that they can become an important pillar as an additional source of support. However, the emphasis here should clearly be on additional support. It is crucial to consider the ethics of using robots to care for the elderly and not to neglect the importance of interpersonal contact and quality of care for the sake of efficiency.
What are your thoughts on the utilization of AI and robotics in elderly care?

Hi Nina,
I totally agree that robots should be seen as additional support in the healthcare! I really like your topic, coincidentally I wrote my research project in high school about this.
Already 5 years ago, I visited Japan and saw robots like Pepper and Paro. At that moment, I still had never heard of these robots in Europe and I really like it that these robots are getting better known and accepted throughout the years. Although it should be seen as additional support, I do believe that it is crucial to implement robots in the healthcare sector.
Indeed, pets are proven to help against loneliness and Paro could be seen as a robot pet, which supports depressed or demented patients. Of course a nurse should still visit elderly patients, but I believe that service and companion robots could improve the healthcare. Moreover, in my opinion, robots could take-over some basic tasks of nurses and give elderly people to chance to live longer at home. I see the robot Pearl as a great opportunity to improve well-being, however I do also believe that it is still important that humans do pass by to check. In this case, nurses could check the robot and check care of any extra tasks.
