Robots with all kinds of functionalities are currently being developed to address a large range of possible tasks; for instance, while they are already very common in factories for very repetitive, often high-risk tasks, researchers are now working on robots that can be programmed by workers themselves so that they can address even more tasks and work flexibly among human workers. Similarly, robots are being developed to work in the service industry, for instance, as waiters, receptionists or delivery robots. Furthermore, researchers are working on robots that can support work in elderly care, where robots are expected to assist care personnel especially on the time consuming or hard tasks, like feeding or lifting respectively, but also to entertain, engage, comfort or guide. Similarly, robots are developed to instruct and entertain children, to tutor them in math or in a second language or to provide them with company in adverse circumstances, like long-term hospitalization. In general, robots are being developed to assist with or take over a large range of tasks hitherto reserved to humans. Robots thus come in a multitude of different forms, functionalities and behaviors; for instance, they may resemble people or animals, but they may also come in the form of moving boxes, drones or robotic arms. While there is no single accepted definition of robots, robots are typically embodied such that they have physical bodies (though many robots have ‘digital twins’, i.e. they may be simulated), and they have sensing capabilities with which they take aspects of their context into account, as well as the capability to act upon this context to interact with the world (cf. Dautenhahn et al. 2002).
