Autonomous mobile robot

An autonomous mobile robot, comprising:

• a moving mechanism;
• an autonomous movement controller configured to control the moving mechanism;
• a self-location recognition unit configured to sense a self-location of the autonomous mobile robot within an active area;
• a map data storage unit configured to store a map data on locations of marks formed on the active area;
• a slit light device configured to irradiate a detection area with slit light;
• an infrared device configured to irradiate a detection area with infrared rays;
• a switch determination unit configured to compare a mark-formed region stored in the map data storage unit and the self-location sensed by the self-location recognition unit, and then, configured to switch between the slit light device and the infrared device, based on a result of the comparison;
• a capture unit configured to capture an image of the detection area irradiated by the slit light or infrared rays;
• a road surface sensing unit configured to detect conditions of a road surface by analyzing the captured image of the detection area being irradiated with the slit light;
• and
• a mark sensing unit configured to detect marks by analyzing the captured image of the detection area being irradiated with the infrared rays,
• wherein the infrared device irradiates the detection area upon the self-location being within the mark-formed region, while the slit light device irradiates the detection area upon the self-location being out of the mark-formed region.
