In old days, it has been said that in one of the robot villages, there was a robot girl whom the entire robots fell in love with, and everyone wanted to marry her, that is why they named her the DELBAR robot. Her robot suitors were so many that she decided not to be seen in the public eye of robots anymore, and to spend most of her time in nature and mountains. A long time passed, and no one saw him again, and the young robots no longer believed that such a robot existed, so they called him a legend. Although some reports indicate that he has seen in springs and some places in the forest, the robots do not believe the words of those who have seen him, and they say that the robot lover is a legend.Little by little, DELBAR Robot’s name changed to Delbo, which was an abbreviation of his own name. She is a symbol of a lover that is hard to come by, and only seen by those who are true lovers. Robots who have seen Delbo have also said that in one moment all nature went out of their view. Delbo is the name of all robot girls, which robots love to marry with, and now she only mentioned as a legend, which we know is a real lover. DELBO is one of ZEM group’s robot, combination of art, engineering, and creativity.
