On September 3, 2112, it was born in the Matsushita factory in Tokyo, Japan. On the production line of the day, it is No. 1 (the second one) produced after No. 0 (the first one). An accident occurred during the manufacturing process, causing one of the screws to fall and become a "special" robot. Later, he was sent to a special class at the Robot School where he met the "Dora A Dream Seven Kid" and became friends with them. After that, Doraemon participated in the robot sales meeting held in the robot school. At that time, the child's World Repair accidentally pressed the purchase button, so I bought the Doraemon (from the 2112 Doraemon). Birth"). In "The Birth of Doraemon in 2112", Doraemon is a robot for child care, working in the mysterious field of Daxiong. In order to change the bad Daxiong, Shi Xiu decided to call Dora A to return to the 20th century to help Daxiong.
Doraemon's body color is blue, face, belly, hands, feet are white. The nose is red. But when I was just making it, Doraemon was yellow and had ears. In the early days of serialization, Doraemon is fatter and deeper in body color. It is light blue. Doraemon's body has anti-gravity function, so the feet will not be contaminated with dust, and there is no need to take a bath with water. Just wipe it with a towel, but in "Reversing the Magic Flute", A dream says to go to take a bath. Doraemon's hand is a ball  shape that absorbs things. Because there is no finger, the guessing is always lost to others.
The energy source of Doraemon comes from food. All the things that are eaten are converted into energy by the atomic furnace in the body, and there is no need to go to the toilet. Doraemon will also be thirsty, need to drink water, and drink cold drinks to cool off.
Doraemon's body is very strong and can be active in the deep sea and the universe. (The big long story of Daxiong's Undersea Ghost Rock City). But Doraemon is afraid of heat and cold, but also afraid of mosquito bites. In the 12 volumes of 'Ghosts', Doraemon even said, "Is this kind of advanced robot will be bitten by mosquitoes." In addition, he will also sneeze and even catch a cold.
According to the film 'The Birth of Doraemon in 2112', the performance of the Doraemon was particularly poor because it was dropped from a height after the electric shock of the time criminal and a screw was missing. But the setting in the Doraemon is: Doraemon and his sister are using the same oil in the oil tank, and the manufacturing of the Doraemon is the upper light oil, which is manufactured. The beauty of the United States is the heavy oil that has been precipitated, so the quality of the Doraemon is particularly bad. This setting was once again enabled in the Paddy A Dream TV animation after 2005.
