Abstract: [Problem] To provide a calibration apparatus capable of reducing a workload for calibrating a position and a direction of each range sensor. [Solving Means] In the measurement arithmetic unit 100, the social group identification portion 5610 identifies a group candidate that is detected as a group out of moving measuring objects in each laser range finder. The group comparison portion 5612 identifies a group in agreement for each pair of the laser range finder, and calculates the relative position of each pair of the laser range finder according to the position and the directions of the identified matching group. The network position identifying portion 5620 calibrates the position and the direction of each laser range finder in the sensor network coordinate system such that the error of the position of the object observed in common from each pair becomes minimum.

Abstract: A robot control system detects a position and a direction of each user by a plurality of range image sensors provided in an exhibition hall. A central controller records an inspection action after a user attends the exhibition hall until the user leaves to generate an inspection action table. When the user attends again, the central controller reads a history of inspection action from the inspection action table. Then, the central controller chooses from an utterance content table an utterance content containing a phrase that mentions the inspection action included in the history at a time of last time attendance, determines the utterance content, and makes a robot output the determined utterance content to the user.
