Disclosed herein is a mobile robot, and system and method for autonomous
navigation of the same. The mobile robot includes a communications module
for transmitting a light source control signal to selectively control
light sources of a landmark array to flicker, an image processing module
for calculating image coordinates of the light sources from an image
signal, a pose calculation module for calculating position coordinates of
the mobile robot, a motion control module for calculating a moving path
and controlling the mobile robot to move along the moving path, and a
main control module for controlling interoperations of the modules and
general operations of the mobile robot.
