Abstract:
PURPOSE: A landmark of autonomous mobile robot for traveling across space with different coordinate and system comprising the same and method of moving using the same are provided to having a location recognition system freely move to a different space by including a bottom mark. CONSTITUTION: Bottom marks(110A, 110B) are respectively set up at different spaces and provide location information based on coordinate information. A medium mark(120) is set up between different spaces and provides location information about direction change of a freely moving robot. A link mark(130A, 130B) is set up between the bottom and medium marks and among the medium marks. The link mark guides the freely moving robot to move toward the bottom and medium marks.

PURPOSE: A mapping apparatus of a moving body and method thereof are provided to convert a vector model based map and a raster model based map into each standard model map. CONSTITUTION: A map preparation data collecting block(106) collects map data. A vector model based map making block(108) generates a local vector map and a vector model based map. The vector model based map preparation block performs location compensation of a movable body. A raster model based map preparation block(110) prepares a raster model based map. A standard map converting block(112) converts the vector model based map and the raster model based map into a standard model map.
Abstract:
PURPOSE: A driving data acquisition apparatus and a method thereof are provided to negate the error accumulation property of an encoder and obtain excellent position recognition result using single unit. CONSTITUTION: A display unit(110) displays the trace on a driving surface. A moving body moves on the driving surface. An image acquisition part(120) gets the trace image. A controller(130) compares a first trace image and a second trace image. The controller calculates and outputs the driving information of the moving body.

PURPOSE: A route creation apparatus between areal maps in a broad areal space and a method thereof are provided to efficiently move in a broad areal space by rapidly creating a route to drive between local spaces by using the relationship of local coordinate system. CONSTITUTION: A route creation apparatus between areal maps in a broad area space comprises: a coordinate system replacement unit(101) which converts the local coordinate system of a first local map and a second local map to the world coordinate system of a wide area map corresponding to the broad area space; a route selection unit(103) which determines the moving body movement route to the second local map with passing through a first areal space and a second areal space in the first local map; a coordinate conversion section(105) which changes the local coordinate of the route in the first local map and the route in the second local map into the world coordinate by the world coordinate system; and a route information generating section(107) which creates the movement route information by using the world coordinate corresponding to the moving body movement route. The first local map corresponds with a first areal space in a wide areal space. The second local map corresponds with a second areal space in a wide areal space. The wide area map corresponds with a broad areal space.
Abstract:
A method for rapidly obtaining indoor eco-map with moving body and distant measuring sensor is provided to rapidly obtain an eco-map by using laser sensing information and position information of a moving body in which a sensing part and an encoding part are mounted. If a moving body is operated(S700), position information of the moving body is generated by an encoding part, and distant value information from a sensing part to an object is generated by the sensing part of the moving body. After obtaining the position information and the distant value information(S702), position information and sensing information of the moving body are predicted(S706). Matching of the predicted position and sensing information of the moving body and real measuring information of the moving body is determined(S708). If the predicted information and the real information are matched, the predicted position information of the moving body is renewed, and indoor eco-map is written.
