The gentleman of tomorrow: touchingly reasonable, aesthetic and likable – Care-O-bot 4 is the new archetype of a service robot. It was developed at the Fraunhofer IPA in Stuttgart in close cooperation with Phoenix Design, combining User Experience Design in all its many disciplines. As a matter of course, timeless design, formal and functional precision are vital elements for its deployment in a modern architectural environment – barrier free. Care-O-bot 4 is singularly flexible and elegant. With its slim form, it moves smoothly and fluidly about the room. The intelligent interface and the tactile-visual design quality turn interaction into a cognitive and sensual experience. Being capable of autonomous navigation, identifying obstacles and picking up target objects are only some of its powers. The result: a symbiosis of design and engineering, of function and emotion – seducing users to enter into an interaction right away.
