How do humans control the rover? Based on what principle?

After human beings walked out of the earth, they were not intimidated by the vast universe, but inspired their enthusiasm for exploring the universe, which is an indomitable spirit, and it is the existence of this spirit that human science and technology can develop so fast and human civilization.

to be able to go out of the earth and explore the universe in such a short period of time. The main reason why scientists are so concerned about Mars is that it is somewhat similar to Earth's environment, and probes can land on Mars. Other planetary scientists are also very interested in exploring, such as Venus, if the surface of Venus is similar to Mars, scientists should most want to explore Venus, which is close to the Earth and is also the sister star of the Earth.

So why don't scientists land and explore Venus? The reason is simple, the temperature on the surface of Venus is too high for the atmosphere.

It's also very bad, it's a purgatory.

planet, the probe simply could not land on the surface of Venus.

People control a rover that walks on Mars.

The main thing is the three-point communication method, that is, the earth, an artificial communication satellite, and Mars, so that electromagnetic waves.

In the past, the atmosphere was later launched to Mars by the relay of satellites, and we know that the water vapor and other media in the atmosphere interfere with and weaken the radio waves, and there will be errors when pointing directly from the Earth to Mars. The synchronous communication satellite around the earth itself has energy, and can be charged by solar energy, and the electromagnetic waves emitted by people from the earth (wireless fingers) are amplified again with greater intensity, and there is no medium interference in space, and it is much more convenient to control the rover.

Electromagnetic waves travel at about the speed of light in the universe, so even though they seem far away, they are only a very small delay for electromagnetic waves. It is actually somewhat similar to the control of a remote-controlled car, which is remotely controlled by radio signals. When you give a command, and then the radio signal is transmitted to the control system inside the remote control car, you can complete various movements and actions of the car according to the command.

The control of InSight is somewhat similar to this, but the complexity is much higher, and if the probe wants to land on Mars, it also has to do a lot of work in advance, first landing on Mars through computer simulation on Earth, and then the relevant data and instructions will be entered into the rover after the simulation is successful. The detector relies on these input instructions to get the job done. However, because Mars is relatively far away from the Earth, communication in space must be relayed, and the signals sent by InSight cannot be directly connected with the Earth, and must go through several transits.

This is the same as controlling a remote-controlled toy car, except that the toy car is controlled on Mars, the remote control command is issued, the earth sends a signal to Mars, and then the car receives the signal and can start doing things. However, it takes 20 minutes to travel from the Earth to Mars at the speed of light, and electromagnetic waves also travel at the speed of light. The control rover is relayed by two signal relay satellites, and the person sends a command, which is converted into an electromagnetic wave signal, ** to the relay satellite near the earth, and the earth relay satellite sends a signal to the relay satellite attached to the fire, and the relay satellite of Mars sends a signal to the rover, and the rover can do things according to the instructions.

Humans control the rover through wireless signals, based on digital ** and other related principles.

It uses electromagnetic waves to control the rover, and the principle should be the principle of electromagnetic wave control.

The Mars rover is currently a very popular and fashionable car, the eoswheel rover is even more trendy, you can guess the basic appearance of this scooter when you hear its name, it is composed of a wheel, and the circuit system is installed inside, and it can be used for a long time after charging for about two hours before each use. And the car is a thinking car, which is not to say that the car has thinking, but its action is guided by human thinking, forward, backward, turning these are controlled by people's ideas, simple and easy to operate, and the exercise is very good. If you are proficient in transportation, there is no danger.
