The complete WoZ4U system in the form of an extended deployment UML diagram showing the connected and interacting components, starting with the wizard’s input, and leading to the execution of a command on the robot. The WoZ4U server component maps requests from the frontend to robot API calls and keeps the frontend up-to-date by continuously fetching data from the robot. The frontend is populated with experiment-specific UI elements defined in the configuration file.
