2.1 General attitudes toward robots
Traditionally, robots have been used in industry to assist the human workforce by performing repetitive and dull tasks (Sharkey
2008). For example, robots function well in manufacturing lines where the same task must be performed repeatedly throughout the day (Lopes et al.
2017). Currently, a wide variety of robots are used in addition to those used in industry. Robots can be divided into two categories—industrial robots and service robots [International Federation of Robotics (IFR)
2012]. Robots have also become available for private consumers, for example, robot vacuum cleaners (Forlizzi and DiSalvo
2006).
While the purposes of industrial robots are evident, the uses of service robots, to which category care robots belong (see Okamura et al.
2010), are less clearly defined. The International Organization for Standardization (ISO) defines a service robot as a robot “that performs useful tasks for humans or equipment excluding industrial automation applications” (ISO 8373
2012). Service robots can be defined as those used by service providers or individual consumers to serve people by performing various tasks, for example, vacuum cleaning. Wu et al. (
2012) divide service robots into three categories: (1) monitoring robots (to help observe behavior and health), (2) assistive robots (to provide support to the individual and/or their caregiver in daily tasks), and (3) socially assistive robots (to provide companionship). Examples of these robots are telepresence robots (e.g., Double and Giraff), medicine-dispensing robots (e.g., Evondos), robotic walking aids (e.g., Lea), robotic spoons (e.g., Gyenno), exoskeletons for rehabilitation of the patient (e.g., Indego) or for supporting the care worker (e.g., Laevo, Auxivo), transportation robots for delivering meals and medicine (e.g., TUG), and social robots for therapy, entertainment, and communication (e.g., Paro, JustoCat, Zora, Pepper) (Niemelä et al.
2021; Pirhonen et al.
2019). This development from industrial robots to service robots has brought robots closer to people, with the development of robots that are able to assist people in a variety of tasks, such as indoor transportation (Severinson-Eklund et al.
2003; Summerfield et al.
2011).
Attitudes toward robots have been investigated in many service contexts, for example, at home (de Graaf et al.
2019), in elder-care facilities (Melkas et al.
2020; Tuisku et al.
2019), at school (Fridin and Belokopytov
2014), and for shopping (Doering et al.
2015). These studies have often concentrated on the acceptance of one particular robot. The question of acceptance becomes more abstract when dealing with a general level of acceptance—when the study participants’ perceptions cannot be tied to a known robot. Interestingly, the Europe-wide Eurobarometer surveys (European Commission
2012,
2015) have shown that attitudes toward robots in general are favorable, with 70% of European respondents expressing a positive attitude toward robots. Finland was found to be the fourth most positive country in Europe in relation to the use of robots, with an 85% acceptance rate; only Sweden, Denmark, and the Netherlands reported higher acceptance rates. Turja and Oksanen (
2019) further investigated Eurobarometer data further from the perspective of robot acceptance in the workplace in general. They found that acceptance of robots as assistants at work depends on the individual’s experience, which means that acceptance is more related to the individual’s own principles than to the European country in which they live. A recent study by Latikka et al. (
2021) concerning working life noted that the participants’ attitudes were more positive toward robots as pieces of equipment that are semi-autonomous than toward robots that functioned as autonomous co-workers in the workplace context. This is because the latter may evoke connotations of humans being replaced with robots at work, whereas equipment is more likely to support or complement human work.
The development of the appearance and gestures of robots has mainly concentrated on how robots can be made to act similarly to humans (e.g., Ghazali et al.
2018) or to look like humans (e.g., Walters et al.
2008), although a robot’s appearance depends on the particular tasks it was designed to perform. While these are important aspects of human–robot interaction (HRI), it is equally important to understand how people utilize robots in their daily lives and what new possibilities are arising due to interaction with robots. Human–robot interaction is thus not only about the adaptation to and adoption of robots, but also about developing a richer sociotechnical imagination to enable designers to create robots that better fit into particular social contexts (Šabanović and Chang
2016; see also Nickelsen
2018). The departure point for this study is the need for a broad societal understanding of human–robot interaction.
2.2 Attitudes and acceptance toward care robots
Studies focusing on participants’ experiences and attitudes toward care robots available for utilization in welfare services (Bedaf et al.
2015) include, for example, the therapy seal robot Paro (Wada and Shibata
2007), the socially assistive humanoid robot Zora (Melkas et al.
2020; Tuisku et al.
2019), telepresence robots (Cesta et al.
2016; Koceski and Koceska
2016), and exoskeletons (Sale et al.
2012). In addition to these physical robots, there exist studies of solutions such as voice assistants and chatbots that can be considered to have a social and communicative function in care (e.g., Lee et al.
2020; Skjuve et al.
2021). Acceptance and ethical issues related to socially interactive and therapeutic robots have been studied by Jenkins and Draper (
2015) and by McGlynn et al. (
2017). However, different types of robots may trigger different responses in terms of acceptance, depending on the target group (Robinson et al.
2013).
Concerning public opinion about care robots, while the Eurobarometer data showed favorable attitudes toward robots in general, using robots specifically in health care was seen negatively. Only 22% of the general public in Europe accepted the use of robots in health care, with an 18% acceptance rate in Finland. Literature reviews have also been conducted on the acceptance of robots in various occupational fields (e.g., Savela et al.
2017), and while the results show that attitudes toward robots are positive in many fields of work (e.g., education, business, and industry), in the case of care work, attitudes are more negative. These results are mainly explained by the fact that people consider it inhumane for a robot to take care of a person.
The general public’s attitudes toward the use of robots in the care of older people were examined in a media analysis that showed that opinions were mostly negative (Tuisku et al.
2019). It was found that the general public’s main concern was that robots would replace human-to-human contact and care. However, based on these results, it was obvious that the general public did not have sufficient knowledge about the use of robots in welfare services. For the general public, media coverage may provide the only information they receive regarding the use of care robots.
Broadbent et al. (
2010) investigated general perceptions relating to the use of robots in welfare services. Interestingly, the participants saw many benefits and applications for health-care robots, including performing simple medical procedures and providing physical assistance. However, some participants were concerned about reliability, safety, and the loss of personal care. The researchers concluded that perceptions about the use of robots were influenced by the participants’ prior exposure to robots in literature or in entertainment media. Previous research has shown that exposure to robots positively affected attitudes toward them (Broadbent et al.
2010; Melkas et al.
2020), although other studies have obtained contradictory results (Kristoffersson et al.
2011).
In addition to focusing on public opinion, prior research on the acceptance of robots in welfare services has focused on the attitudes of actual users, that is, older people and care workers (Broadbent et al.
2012; Coco et al.
2018; Melkas et al.
2020; Turja et al.
2018). Older people interact with a robot in the course of receiving services from it, while care workers are often the ones who control the robot. The results concerning the attitudes of actual users—older people and their caregivers—indicated that when people had more knowledge about robots, were shown a robot, or were able to use one, their attitudes toward robots became more positive (e.g., Johansson-Pajala et al.,
2019). Some negative connotations seem to be attached to the idea of care robots, along with an ambiguity in terminology, which may lead to misunderstandings or ‘colored’ (distorted) information (Pekkarinen et al.
2020a,
b). Papadopoulos et al. (
2018) reported that health-care workers have mixed views on the use of robots in care settings, and few health-care professionals had used or even seen a robot. A lack of knowledge creates false impressions concerning robots’ capabilities and risks (Johansson-Pajala et al.
2020). Providing hands-on experience and promoting increased awareness and education about what care robots can do are necessary to move away from preconceptions based on fiction and imaginary images of robots (Frennert et al.
2021).
Attitudes toward care robots have also been studied through surveys. Turja et al. (
2018) investigated the attitudes of Finnish health-care workers toward the use of robots in welfare services and discovered that the views of the health-care workers were generally negative. However, they considered a robot acceptable for doing certain work tasks, such as heavy lifting. It seems that care workers have reservations about the use of robots in welfare services. On the other hand, Melkas et al. (
2020) found that the attitudes of care workers changed when they were able to interact with a robot and witness the positive attitudes of older people. Niemelä et al. (
2016) noted in their study that care workers had negative prejudices toward the use of social robots in care, but valued them for their positive social and emotional impact on older residents.
While many of the experiences reported with care robots have been positive (see Beeuwkes Buntin et al.
2011; Andtfolk et al.
2021), certain concerns persist regarding the use of robots in welfare services. Welfare services are traditionally seen as a field in which only humans can perform (Parks
2010; Sparrow and Sparrow
2006). Sharkey and Sharkey (
2012) list six concerns regarding the use of robots in elderly care, including (1) a potential reduction in the amount of human contact, (2) an increased feeling of objectification and loss of control, (3) loss of privacy, (4) loss of personal liberty, (5) deception and infantilization, and (6) unclear circumstances under which older people should be allowed to control a robot. The principle fear in utilizing robots in welfare services is the loss of human contact (Sharkey and Sharkey
2010). This fear is expressed by both care personnel who may not have had any experience using a robot with older people and by the general public (Tuisku et al.
2019). However, as many studies show, social robots are not meant to substitute for care workers, but rather to complement them (Pfadenhauer and Dukat
2015), and in fact, additional caregivers may be needed when utilizing a robot with elderly clients (Melkas et al.
2020). In recent years, this fear has characterized the discussion around the utilization of robots.
In the few studies focusing on the views of decision-makers, decision-makers have been shown to have more positive attitudes toward care robots than ordinary employees. For example, Tuisku et al. (
2019) found that managers who had been actively involved in the acquisition of a care robot for elderly care saw it as a positive tool. Beedholm et al. (
2015) investigated the attitudes of different stakeholders (management, nursing staff, and older people) regarding the acquisition of a robot bath for a nursing home in Denmark. Their interviews revealed that attitudes were highly dependent on the respondent’s role. The managers who were responsible for acquiring the robot bath showed the most positive attitude. A study by Niemelä et al. (
2016) showed that managers were interested in acquiring a lifting robot, while the caregivers were distrustful and preferred a therapy robot seal. Thus, acceptance may also depend on the robot in question, for example, its appearance and usability (Pfadenhauer and Dukat
2015; Johansson-Pajala et al.
2020).
Gallego et al. (
2008) identified the importance of decision-makers’ roles in acquiring new health-care technologies. Their study showed that decision-makers, in this case, senior health service managers, nurse managers, and senior medical clinicians, were responsible for the acquisition of new health-care technologies and played an active role in acquiring such solutions. This study revealed that while the managers had to adhere to constraints imposed at a higher level, such as funding issues, they were still in a position to make decisions regarding the kind of technology to be purchased. Thus, people at the level of management and policy-making play a considerable role in the initial introduction of technologies in the care sector, and this is why their motivation and attitudes need to be studied. In addition, they play an important role in the broader stakeholder network.
