Broadcasting is a commonly used feature in wireless networking, e.g. for file distribution, re-tasking, event notification, or miscellaneous maintenance. Due to the limited resourc...
We present a novel geometric model for robot mapping suited for robots equipped with a laser range finder. The geometric representation is based on shape. Cyclic ordered sets of p...
