Robots in the service segment fulfil different tasks than those in other industries. As assistants to human beings, service robots have to reproduce human actions in order for us to accept them. Care-O-bot 4 embodies an exciting new archetype of such a service robot, since it has a particular human appeal. It moves smoothly and elegantly through rooms. Featuring elaborate gestures and facial expressions, it evokes the emotions of everybody involved. In addition, this robot can navigate autonomously, automatically detect obstacles and pick up requested objects. A highly fascinating feature for users is the interaction with the Care-O-bot 4, which happens either via speech recognition or with a clearly designed, almost playfully appealing interface on the robot’s head. A modular design concept allows for a customised set-up for different tasks. This makes the robot versatile in use, opening up new areas of application. In an impressive symbiosis of research, engineering and design, this service robot combines an intelligent interface with a design quality that is also appealing to the touch – interaction with it becomes a cognitive-sensual experience, evoking positive emotions.
