Robotic barman and robotic barista are collaborative robots responding to user orders. These orders are made using a tablet that contains an app where users can choose a drink of their choice. After entering a name, orders are sent to the server where they are queued and executed one by one. During the process of making the beverage, users can try to interact with a robot that is programmed so that they will not hurt anyone in direct contact. You can try to stop the robot, move the whole shoulder or literally shake hands with it.
