As promised at an old post about the Summer School at Bremen. Below there are some pictures from the Co3AUVs Summer School at the Jacobs University of Bremen.

The first summer school on Cooperative Cognitive Control for Autonomous Underwater Vehicles (Co3-AUVs) was held in July_2010 at Jacobs University in Bremen, Germany. The summer school is organized within the Co3-AUVs project.

The Co3-AUVs summer school has a strong hands-on character. Participants receive the opportunity to work with state of the art marine robotics equipment and to engage in practical experiments. In addition, they are introduced to an Open Source marine robotics simulator featuring among others 3D visualization and physics, which allows them to continue possible work started in the summer school. Students on all levels (PhD /graduate/undergrad) from outside the Co3-AUVs project are particularly welcome to participate in the summer school.

The equipment used in the summer school for hands-on experiences includes complete AUV as well as core components like different types of thrusters, sonars, cameras, attitude and acceleration sensors, underwater modems and ranging. In addition to an introduction to the different components, the summer school concentrates in its sessions on Simultaneous Localization and Mapping (SLAM) in marine scenarios using vision and sonar both for 2D and 3D mapping and navigation.

Also, I have put just a few pictures from the pleasant and beautiful city of Bremen and from the Munich Airport to don`t make this post very long. Yes, they were having some party for the Audi A1 and I was having my shake at the McDonalds at the same time
