Mobility is a key driver of the development of large urban areas and tall buildings. The level of automation during construction and operation of such urban areas is continuously increasing. Humans do not only outsource work to robots, but they also share their workspace and mobility space with them, as they serve different purposes and provide services. How does robotic automation impact the design of mobility services, buildings, smart cities and our interaction with them? Socially-aware robots will be an essential asset to design robot-augmented building services, because such services will transfomr urban areas into a co-mobility space, shared among humans and robots. The team developed multiple robot prototypes to support elevator installation or to act as an elevator service companion. The design of these prototypes, as well as their human machine interface, while functional, can still be improved to provide a superior user experience, mechanically as well as via apps, voice, or gestures.
