This extended abstract describes a project to make a robot travel autonomously across a public nature park. The challenge is to detect and follow the right path across junctions and open squares avoiding people and obstacles. The robot is equipped with a laser scanner, a (low accuracy) GPS, wheel odometry and a rate gyro. The initial results shows that this configuration is (almost) sufficient to traverse the park, when following simple preplanned guidelines. This paper describes the decisions and solutions, results so far, and expected further development.
