This research proposes the use of a small animal robot that encourages users to improve the room environment.The robot measures room temperature using a built-in temperature sensor (DHT11) and evaluates the risk of a possible heat stroke. In cases where the risk of a heat stroke is high, the robot demands the user to lower the room temperature by imitating motion that suggests suffering.Through observing users’ behavioral changes, this work assesses the effectiveness of setting “helping behavior towards robots” as a motive.
