What little-known cold knowledge does Doraemon have?

I think there are several points. The following are personal opinions and have no other meaning. The pictures are all from the Internet.

Doraemon is probably the childhood memory of many people. This work was originally a science fiction work, but its essence is a prospect for the future. Everything is a long-cherished wish for future technology. When we were young, we only liked watching. When we go back to see it when we grow up, there will be many questions, some of which are set and some are thinking about its principle. Then let's talk about some cold knowledge that few people know. I'm sure you'll be shocked.

Why does Doraemon have a sister?

Doraemon is a parenting robot. It stands to reason that even if robots are mass-produced, they are individuals. But why does he still have a sister, and her performance is much better than him? This is because Doraemon and its sister Doraemon are made of the same batch of oil. Doraemon uses its floating oil and Doraemon uses the essence of precipitation, so there will be brothers and sisters. This is really a puzzling thing.

Why do robots eat and drink water without going to the toilet?

Doraemon also wants to eat, and if she doesn't eat, she will be hungry. But unlike human digestion, Doraemon can completely convert food into energy through the atomic furnace in the body, so it doesn't need to go to the toilet. So! It stands to reason that Doraemon can maintain life even if she dreams of eating soil, but she definitely wants to eat delicious food with taste. This is amazing.

In fact, Doraemon never touches the ground.

Doraemon doesn't wear shoes in the setting, but what he often goes in and out of the room won't pollute the floor. There's nothing to worry about. Doraemon has an anti-gravity suspension device, and its feet are always 3 mm from the ground, which means that Doraemon has been floating in the air, naturally it will not get dirty. This is simply a magical thing.

Doraemon has a four-dimensional pocket on her belly, which leads directly to four-dimensional space, and no matter how many things can be put down. Afraid of rats. It turns out that Doraemon also has fear.

2 1 12 was born on September 3rd in Tokyo, Japan. On the production line that day, 1 (the second set) was produced after 0 (the first set). An accident happened in the manufacturing process, which caused one of the screws to fall off and become a "special" robot. After that, he was sent to a special class in Robot School, where he met Doraemon's seven boys and made friends with them. After that, Doraemon attended the robot sales meeting held in the robot school. At that time, she was the child's teacher (セワシ) and accidentally pressed the buy button, so she bought Doraemon (born from Doraemon 2 1 12). In 2 1 12 The Birth of Doraemon, Doraemon, as a robot to take care of children, works in Shinhiko's great-grandson's house. In order to change poor Daxiong, Shi Xiu decided to ask Doraemon to return to the 20th century to help Daxiong. [ 1]
