Obstacle Avoidance and Path Planning Using a Sparse Array of Sonars
Matei Ciocarlie · 2004
This paper proposes an exploration method for robots equipped with a set of sonar sensors that does not allow for complete coverage of the robot's close surroundings. In such cases, there is a high risk of collision with possible undetected obstacles. The proposed method, adapted for use in urban outdoors environments, minimizes such risks while guiding the robot towards a predefined target location. During the process, a compact and accurate representation of the environment can be obtained.
