ACE Robot Interacting with Pedestrians (IMAGE) Technical University of Munich (TUM) Caption Navigating only by asking pedestrians it encountered for directions, the robot called ACE, or Autonomous City Explorer, made its way from the institute where it was built -- at TUM, the Technische Universitaet Muenchen -- to Marienplatz roughly a mile away. A project of the Munich-based CoTeSys collaboration, ACE is part of a larger effort to enable more natural, effective, and safe interaction between machines and people.
