Movement robot

A movement robot comprising:

• a robot body;
• a driving mechanism configured to move the robot body;
• a detector configured to detect a distance to a surrounding object in a movement area of the robot body and a direction of the object;
• an instruction receiver configured to receive an instruction to perform a certain operation mode selected from two or more operation modes for the robot body;
• and
• a controller configured to control the driving mechanism and the detector,
• wherein the controller includes
• a storage configured to store detection information detected by the detector in chronological order,
• a map producer configured to produce, and update as needed, a map of a periphery of the robot body based on the detection information stored in the storage to store the map in the storage,
• a movement body detector configured to detect a movement body different from the robot body by comparing a new map produced by the map producer and an old map stored in the storage,
• a robot route information storage configured to associate the map produced by the map producer with robot route information indicating a movement route of the robot body to store the map in the storage,
• a movement body route information storage configured to associate the map produced by the map producer with movement body route information indicating a movement route of the movement body to store the map in the storage, and
• a coordinated movement control section controller configured to move the robot body in coordination with the movement body based on the robot route information and the movement body route information, wherein
• upon receipt of the instruction related to perform the certain operation mode by the instruction receiver, the coordinated movement controller acquires the movement route of the movement body and thereafter performs the certain operation mode by moving the robot body in coordination with the movement body based on the movement body route information.
