Abstract: Each robot effectively appeals its own device even when multiple robots are present in surroundings. A robot comprises a person detector, an appeal permitter, and a movement controller. The person detector detects a person. The appeal permitter permits execution of an appealing movement attracting interest of a person. The movement controller executes the appealing movement when the person detector detects a person and execution of the appealing movement is permitted by the appeal permitter.

Abstract: A robot control device (a communication terminal) is a robot control device controlling a student robot playing a role of a student learning with a user and includes acquirer (a learning performance acquirer) that acquires an indicator presenting academic ability of the user, determiner (a student robot operation controller) that determines an operation of the student robot based on the indicator presenting the academic ability of the user acquired by the acquirer, and executor (the student robot operation controller) that makes the student robot execute the operation determined by the determiner.

Abstract: A biometric authentication device has a structure member which is wearable to a user, and a biological information acquisition unit that acquires biological information of the user, and a biometric authentication unit that performs authentication of the user. The biological information acquisition unit is provided in a position where a finger of the user in contact when the structure member is worn/removed to/from the user, acquires first biological information with the finger of the user in contact with the biological information acquisition unit and second biological information which is at least one of a finger direction and action data, the finger direction is a direction of the finger in contact with the biological information acquisition unit and the action data is a data corresponding to spatial movement of the biometric authentication device when the structure member is worn/removed to/from the user.
