Only cleaning robots Cleaning robots Every day, hard-working cleaning workers are busy non-stop. They are happy and worried: they are happy that they can serve the people, but they are worried that there are too many things to do.

You would think that you could let a robot help.

Yes, there are already robots that can clean.

They can clean every place, sweep them into trash cans, and send them to the garbage station.

These robots are so smart and capable, they seem to be really good helpers for cleaning workers!

But the cleaners were still not satisfied.

If there is no electricity, they will "go on strike". A city the size of a city is full of buildings, and we cannot let robots drag long wires around.

You will think, you can use batteries! Then you have to charge the robot or change the batteries frequently.

Because the battery will soon run out, and if it runs out of power, the robot will "starve".

It would be too troublesome to ask the cleaning workers to find the "starving" robots one by one.

Can the robot charge itself?

Scientists are working on robots that can work by just "eating" garbage on the ground.

If a special battery is installed in the belly of this kind of robot, it can turn the garbage it "eats" into energy, and then turn the energy into electricity.

When sweeping the floor, these robots can work non-stop as long as they "eat" the garbage on the ground.

With this kind of robot that "eats" garbage, it will be much easier for cleaning workers. They only need to sit in the office and direct them.

With the development of science and technology, human beings' high technology is wonderful. I must study hard now, grow up and contribute to the motherland, and strive to create such advanced robots.
