摘要： Disclosed are a map exploration method for exploring an unknown region by a robot, a chip, and the robot. The map exploration method includes: step S1: acquiring frontier points that meet a preset passing condition by means of a frontier detector based on a rapid exploration random tree algorithm; step S2: filtering out frontier points for exploring the unknown region among the frontier points acquired in step S1; step S3: on the basis of navigation costs of frontier points explored by the robot at a current position and income information corresponding to the navigation costs, and by considering a passable condition of the frontier points, selecting a frontier point with the highest revenue from the frontier points filtered out in step S2, configuring the frontier point as a target point, and then controlling the robot to move from the current position to the target point, thereby building a local map.

摘要： A self-position estimation device includes a peripheral object information acquisition unit acquiring peripheral object information, a storage unit storing map information and dynamic object information, a dynamic object determination unit, and a self-position estimation unit. The dynamic object information includes fixed portion information and movable portion information. The dynamic object determination unit determines whether or not the dynamic object exists around the moving body by collating the peripheral object information with the fixed portion information, when the dynamic object determination unit determines that the dynamic object exists around the moving body, the self-position estimation unit estimates the position of the moving body in the map information by excluding the portion corresponding to the dynamic object from the peripheral object information and collating the map information with the peripheral object information.

摘要： A map generation device that generates a route. The map generation device includes: a node detector that detects a node; a node information obtainer that obtains detected node information including location information of the detected node and path information indicating a positional relationship between the detected node and a path connected to the detected node; a node determiner that determines whether the detected node information matches previously-reached node information; a node information adder that adds, to the route map, the detected node information as new previously-reached node information when the node determiner determines a mismatch; and a map corrector that, when the node determiner determines a match, determines that the detected node corresponding to the detected node information and a node corresponding to the previously-reached node information are a same node and corrects the route map.

摘要： A system and method for a motorized mobile chair use a plurality of sensors having a plurality of sensor types to detect a plurality of objects and generate sensor data about the detected objects, each of the detected objects being a person, the sensor data about the objects comprising a plurality of range measurements to the people and a plurality of bearing measurements to the people. The system has at least one processor to receive the sensor data about the people, group the detected people into a plurality of zones, determine a closest person in each zone, and generate one or more control signals to cause the motorized mobile chair to match a speed and a direction of the closest person in the zone corresponding to a direction of travel of the motorized mobile chair while at least approximately maintaining a selected space to the closest person in the zone corresponding to the direction of travel of the motorized mobile chair.

摘要： A travel map creating apparatus includes a position sensor obtaining the positional relationship of an adjacent object relative to the apparatus; a floor map creator creating a floor map based on the positional relationship; a self-position calculator calculating the self-position on the floor map; a marker identifier identifying a marker; a marker position calculator calculating the relative position of the marker to the apparatus; a mode switcher switching the mode of the apparatus between a floor map creation mode and a marker identification mode; a restricted access information generator, based on the floor map, the self-position, and the relative position of the marker, defining a boundary of a restricted area to which the entry of an autonomous mobile robot is prohibited and generating restricted access information including the boundary; and a travel map creator creating a travel map including the defined restricted area based on the restricted access information.
