“…Two German participants indicated to have already known the Floka robot. The German data was previously analyzed and published in work on the impact of robots' head-body relations on participants' perceptions of Meka vs. Flobi vs. Floka [15]. Sample sizes were specified according to the heuristic that statistical requirements are fulfilled with a minimum of 20 participants per condition [28].…”

“…Participants either rated Meka or Floka (see Figure 1). On top of each page of the online survey, colored photographs (465px × 231px) depicted the respective robot from three perspectives (frontal, about 45°, and 90°, [15]).

“…To facilitate a pleasant HRI, robots should feature humanlike characteristics, but still appear technical enough to display their nonhuman characteristics [12], [13], [14]. For instance, a humanlike torso, facial social cues, and the relation between width and height of a robot head determine a robot's humanlikeness (e.g., [12], [13], [15]). The wider a robot head relative to its height, the less it is perceived as humanlike [12].…”

“…The wider a robot head relative to its height, the less it is perceived as humanlike [12]. Similarly, humanlikeness ratings depend on whether participants evaluate a robot head's portrait or the holistic robot platform [15].…”

“…Some features of the Flobi head had to be redesigned to match the Meka wheelbase. Compared to Flobi, Floka's head is broader, has smaller eyes, and a new hair part (see [15] for results of a study with a German sample investigating the impact of robots' body-head relation on the overall perception of Meka vs. Flobi vs. Floka).…”

In the present study, we compared Japanese and German participants' perceptions of social robots. To do so, participants from both cultural backgrounds evaluated two types of service robots designed for use in the smart home context. One of the prototypes featured a rather technical appearance, whereas the other prototype featured a newly designed social robot head. Against our predictions, Japanese and German participants evaluated both robot types similarly. Japanese participants generally showed a stronger tendency to anthropomorphize nonhuman agents and attributed more mind, particularly on the experience dimension, to both robot types than German participants. Nonetheless, Japanese and German participants attributed similar levels of agency to both robot types. Unexpectedly, Japanese participants perceived the robots even as less humanlike than German participants. As predicted, Japanese participants reported less attitudinal robot acceptance and tended to show less trust toward both robot types than Germans. Japanese and Germans indicated similar levels of robot anxiety, perceived uncanniness, and robot likeability. Japanese and German participants generally perceived the robots rather as machines and tools than as human companions. Especially German participants wanted to use the robots for rather safe, boring, and simple tasks that do not require any direct interaction with them. Japanese and German participants were not yet familiar with robots and showed less positive attitudes toward them than widely believed (e.g., [1]). Implications how to gain a more realistic view on users' perceptions of robots to enable a fruitful and comfortable HRI are discussed. *This research was supported by the Cluster of Excellence Cognitive Interaction Technology 'CITEC' (EXC 277) at Bielefeld University, which is funded by the German Research Foundation (DFG). It is further related to the European Project CODEFROR (FP7-PIRSES-2013-612555). might perceive robots differently: Shinto and Buddhism are prevalent religions in Japan, while German culture is influenced by Christianity. A Shinto legend holds that Japanese islands were formed by two gods who became progenitors of the gods of Shinto religion and of the first Emperor of Japan [3]. This belief resulted in a deep respect for nature, animals, gods, and heroes. Further, Japanese people believe that a soul, humanlike traits, and intentions are inherent in any entity, such as in gods, heroes, animals, and nature. This is also reflected in Japanese popular culture in which various kinds of nonhuman agents, including robots, are presented as having humanlike traits [4]. According to [5], anthropomorphism, the tendency to ascribe human traits to nonhuman agents, helps to understand others' behavior and thus might reduce uncertainty. Accordingly, one might assume that the tendency to anthropomorphize nonhuman agents and the prevalence of robots in Japanese popular culture is linked to more positive evaluations of HRI and less anxiety toward robots than in Western countries.

Attitudes towards robots are not always unequivocally positive or negative: when attitudes encompass both strong positive and strong negative evaluations about an attitude object, people experience an unpleasant state of evaluative conflict, called ambivalence. To shed light on ambivalence towards robots, we conducted a mixed-methods experiment with N = 163 German university students that investigated the influence of robot autonomy on robot-related attitudes. With technological progress, robots become increasingly autonomous. We hypothesized that high levels of robot autonomy would increase both positive and negative robot-related evaluations, resulting in more attitudinal ambivalence. We experimentally manipulated robot autonomy through text vignettes and assessed objective ambivalence (i.e., the amount of reported conflicting thoughts and feelings) and subjective ambivalence (i.e., self-reported experienced conflict) towards the robot ‘VIVA’ using qualitative and quantitative measures. Autonomy did not impact objective ambivalence. However, subjective ambivalence was higher towards the robot high versus low in autonomy. Interestingly, this effect turned non-significant when controlling for individual differences in technology commitment. Qualitative results were categorized by two independent raters into assets (e.g., assistance, companionship) and risks (e.g., privacy/data security, social isolation). Taken together, the present research demonstrated that attitudes towards robots are indeed ambivalent and that this ambivalence might influence behavioral intentions towards robots. Moreover, the findings highlight the important role of technology commitment. Finally, qualitative results shed light on potential users’ concerns and aspirations. This way, these data provide useful insights into factors that facilitate human–robot research.
