ACE - The Autonomous City Explorer Project
As robots are gradually leaving highly structured factory environments and moving into human populated environments, they need to possess more complex cognitive abilities. Not only do they have to operate efficiently and safely in natural populated environments, but also be able to achieve higher levels of cooperation and interaction with humans. The Autonomous City Explorer (ACE) project envisions to create a robot that will autonomously navigate in an unstructured urban environment and find its way through interaction with humans. To achieve this, research results from the fields of autonomous navigation, path planning, environment modeling, and human-robot interaction are combined.
Videos
ACE has its own channel on YouTube (www.youtube.com/user/AutonomousCityExplor), where there are videos about the project and experiment, a trailer, and the acceptance speech for the IJCAI-09 AI Video Competition "most innovative video" award.
Research fields
Navigation and localization
- Particle filter based SLAM and moving objects tracking

Researchers
- The ACE team at the Marienplatz in Munich.
The evolution of ACE.
- ACE aged 1 month, 6 months, 12 months, 18 months.
- ACE at the Stachus in Munich, interacting with pedestrians
Field Experiments
July 2007: Field experiment and user studies at the Stachus (Munich) collaboratively with the University of Salzburg.
July 2008: ACE went autonomously through the Munich
pedestrian area to the Marienplatz.
August 2008: ACE went autonomously from the lab to the Marienplatz in Munich. It did not use any map knowledge or GPS and found its way solely from information given from passers-by. (Everybody who gave directions to ACE: thank you.)
- The route from the TUM to the Marienplatz.
- ACE is being interviewed.
October 2008: ACE could be seen in the Deutsches Museum, during the "Long Night of Munich's Museums".
