Method for building spatial map, method for searching optimum traveling path using spatial map and robot control device using the same

摘要

PURPOSE: A map generating method using an autonomously traveling robot for generating a spatial map, a method for producing an optimum traveling path using a spatial map, and a robot control device using the same are provided to produce an optimum traveling path by generating a spatial map using an autonomously traveling robot. CONSTITUTION: A spatial map building unit(110) generates a spatial map on the basis of robot global coordinates calculated from robot local coordinates in the space. A travelling path production unit produces an optical travelling path to a destination on the basis of the spatial map. A global coordinate calculation unit(210) calculates the robot global coordinates from the robot local coordinates outputted from each of a plurality of position coordinate systems. An error correction unit(220) senses a RPM(Revolution Per Minute) of a motor of a robot and generates an offset. The error correction unit corrects the errors of the robot global coordinates in the global coordinate calculation unit by using the offset.
