In January 2015, Fraunhofer IPA presented a prototype of the “Care-O-bot® 4” service robot. The charming helper is now proving its worth in the real world. “Paul” the robot has been greeting customers in Saturn-Markt Ingolstadt since the end of October 2016 and directing them towards their desired products. Care-O-bot 4®, alias Paul, approaches Saturn customers and welcomes them to the store. If they ask him about a certain product, he accompanies the customer to the department and points them in the direction of the relevant shelf. As he indulges in small talk about the weather or another subject, Paul turns out to be a most charming contact partner. However, he prefers to leave actual customer service to his human colleagues.
