Abstract: The presently disclosed subject matter includes a system and a method of navigating an unmanned ground vehicle (UGV) vehicle comprising a scanning device and an Inertial Navigation System (INS) being operatively connected to at least one processor. Operating the scanning device for scanning an area surrounding the UGV, and generate scanning output data; Generating, based on the scanning output data, a map representing at least a part of the area, the map being relative to a location of the UGV and comprising cells, each cell is classified to a class selected from at least two classes, comprising traversable and non-traversable, and characterized by dimensions larger than an accumulated drift value of the INS over a predefined distance; receiving INS data indicative of a current location of the UGV and updating a location of the UGV relative to cells in the map based on the INS data.

Abstract: The disclosed subject matter includes a method and system for navigating an unmanned ground vehicle (UGV), that include: generating, based on the scanning output data, a first map comprising a first group of cells and characterized by a first size; generating, based on the scanning output data, a second map representing an area smaller than that of the first map comprising a second group of cells, which are characterized by a second size being smaller than the first size; wherein each cell in the first group of cells and the second group of cells is classified to a class selected from at least two classes, comprising traversable and non-traversable, wherein the second part at least partly overlaps the first part; navigating the UGV based on data deduced from crossing between cells in the first map and second map.

Abstract: The presently disclosed subject matter includes a computerized method and a control system mountable on a vehicle for autonomously controlling the vehicle and enabling to execute a point-turn while avoiding collision with nearby obstacles. More specifically, the proposed technique enables an autonomous vehicle, characterized by an asymmetric contour, to execute a collision free point-turn, in an area crowded with obstacles. The disclosed method enables execution of a point turn quickly, without requiring the vehicle to stop.

Abstract: Thus, according to some examples of the presently disclosed subject matter, in order to reduce path planning time, information that has previously been calculated during planning of a path is reused during planning of other subsequent paths. Using the stored indication reduces time required for planning the path and thus enables to evaluate a greater number of optional paths within a given period of time. This can assist in increasing speed and smoothness of vehicle maneuverability.
