A non-transitory computer-readable recording medium storing a program for interacting with a user while two-dimensionally moving through a predetermined space,
- the program causing a processor of a robot for interacting with the user to execute a process comprising:
- in a case where a microphone acquires a first speech indicating starting of a game of hide-and-seek with the robot, selecting, with reference to a first table stored in the memory, a first region of the predetermined space where a number of blind spots is smallest in the predetermined space, the first table associating a plurality of regions included in the predetermined space and numbers of blind spots present in the plurality of regions with each other;
- controlling a movement mechanism to cause the robot to physically move to the first region;
- causing the speaker to output a first sound;
- counting a predetermined number;
- when counting the predetermined number, causing a sensor that detects an electromagnetic wave or sound wave reflected by an object to trace a movement locus of the user while the user is detectable by the sensor from a stationary position of the robot and identify an end point of the movement locus of the user that is detected by the sensor;
- in a case where the processor has finished counting the predetermined number, causing the speaker to output a sound indicating that the robot has finished counting the predetermined number, and controlling the movement mechanism to cause the robot to physically move through an entire region in the predetermined space through which the robot is able to move;
- in a case where the sensor has not detected the user by a time the robot finishes moving through the entire region, selecting, with reference to a second table stored in the memory, a first blind spot falling within a predetermined range from the end point of the traced movement locus of the user, the second table associating a blind spot in the predetermined space and a position of the blind spot with each other;
- determining whether the robot is to intentionally lose in the game of hide-and-seek or not to intentionally lose in the game of hide-and-seek;
- in a case where the processor has determined that the robot is not to intentionally lose in the game of hide-and-seek, controlling the movement mechanism to cause the robot to physically move to the first blind spot and causing the speaker to output a second sound;
- in a case where the microphone acquires a second speech indicating an admission of defeat in the game of hide-and-seek by the user, causing the speaker to output a third sound;
- in a case where the microphone does not acquire the second speech, causing the speaker to output a fourth sound,
- in a case where the processor has determined that the robot is to intentionally lose,
- selecting, with reference to the second table, a second blind spot falling outside the predetermined range,
- controlling the movement mechanism to cause the robot to physically move to the second blind spot, and
- causing the speaker to output the second sound,
- in a case where the microphone acquires including the second speech, causing the speaker to output the third sound;
- and
- in a case where the microphone does not acquire the second speech, causing the speaker to output the fourth sound.
