Often robots are seen as a means to an end to fulfill a logical objective task. Android robots, on the other hand, provide new possibilities to fulfill emotional tasks and could therefore be integrated into assistive scenarios. We explored this possibility by letting older adults and stakeholders have a conversation with an android robot capable of expressing emotion through facial expressions. The study was carried out with a wizard-of-oz approach and data collected with a mixed methods approach. We found that the participants were encouraged to speak more with the robot due to its smile. Simultaneously, many ethical questions were raised about transparency and manipulation. Our research can give valuable insight into the reaction of older adults to android robots that show emotions.

翻译：机器人通常被视为实现逻辑目标任务的工具。而仿人机器人则为实现情感任务提供了新的可能性，因此可被整合到辅助场景中。我们通过让老年人和利益相关者与一台能够通过面部表情表达情感的仿人机器人进行对话，探索了这一可能性。研究采用"巫师奥兹"方法进行，并采用混合方法收集数据。我们发现，由于机器人的微笑，参与者更愿意与其交谈。同时，关于透明度和操纵性引发了诸多伦理问题。我们的研究为深入了解老年人对展示情感的仿人机器人的反应提供了宝贵见解。
