Information processing device, information processing system, method, and program

A method for controlling a mobile device to follow a target that is mobile, the method comprising:

• capturing with a camera an image of the target to be followed by the mobile device;
• measuring with a distance sensor a distance from the distance sensor to the target;
• recognizing the target with an information processing apparatus comprising target recognition circuitry, the recognizing includes receiving image data of the image captured by the camera and identifying the target as well as a position of the target;
• determining a movement path of the mobile device with movement path circuitry, the determining includes
• creating a following path to follow the target based on sequential position information about the target, and
• conveying information about the following path to a drive apparatus so the drive apparatus can drive the mobile device toward the target, wherein
• the determining includes determining whether the target to be followed moves a predetermined distance measured by the sensor from a current position, and
• under a first condition the target has not moved from the current position, the movement path circuitry does not perform updating of the following path, and
• under a second condition the target moves from the current position, the movement path circuitry creates a new movement path;
• and
• driving a movement of the mobile device with the drive apparatus to follow the following path.
