ROS Summer Schools provide the right starter kit by using robotic hardware and ROS software. Program first starts with some days of introductory courses, before main tasks of mobile robotics, i.e. perception, localization, mapping & path planning will be tackled. The event’s philosophy is: “Learning by doing to get hands-on experience“. Besides acquiring the necessary theorethical knowlegde, all topics will be taught in small groups on real mobile robots. A highlight is a competition (urban challenge) at the end of the summer school: Participants form different teams that have the task to design a typical mobile robotic application like indoor/outdoor exploration. They all use the same hardware, powered by their learnt ROS skills. The ROS Summer School includes also some leasure activities, such as trips to Paris and Cologne (or other nearby cities). Last, but not least we have a farewell barbecue at the end. The ROS Summer School is supported by the ROSIN project of the European Commission.
