The 2003 model of the autonomous robot "AIBO". Showing a mastery of modeling design, the developers created a rounded body based on a spherical motif, looking for a balance of "cute" and "cool." Thanks to a variety of sensors, this "AIBO" has sophisticated image recognition and can express a wide range of emotions. Not only capable of learning and growing, the robot can react when petted. LEDs equipped with static electricity sensors make it possible. This model marked further advances as a partner robot that makes a good companion to its master.
