A method of navigating a robot includes creating a robot navigation map using a map database required for navigation of the robot; and creating a path on which no obstacle is located in the map database using the created robot navigation map. Further, the method of navigating the robot includes primarily controlling the robot so that the robot travels along the created path; and secondarily controlling the robot so that the robot avoids an obstacle on the path.

Method and apparatus for navigating robot

An apparatus for detecting a position and orientation of a mobile object includes: a relative position detection unit for acquiring a relative position with respect to movement of the mobile object; an absolute position detection unit for acquiring an absolute position of the mobile object; and a position updating unit for updating the position and orientation of the mobile object based on an initial or previous position of the mobile object and the relative position. The apparatus further includes: a position correction unit for updating a current position of the mobile object with the absolute position, and correcting the orientation of the mobile object by setting an orientation of the mobile object in the relative position equal to an orientation of the mobile object in the absolute position.

Apparatus and method for detecting position and orientation of mobile object

A method for generating a safe path of a mobile robot includes searching for a whole path from a starting point to a destination point within a map information entered in the robot; extracting information about an expected distance between the robot and a peripheral obstacle when the robot moves along the searched whole path; and correcting the whole path locally using the information about the expected distance from the peripheral obstacle.
