Play, Dreams and Imitation in Robota 167In the Robota dolls and other works [1, 2], we have exploited the robot’sability to imitate another agent, robot or human, to teach it a basic language.The imitation game between user and robot is a means to direct the robot’sattention to specific perceptions of movement, inclination, orientation. Therobot can then be taught words and sentences to describe those perceptions.2. RobotaFigure 20.1 shows a picture of the two original Robota dolls.
