Technology and life: starting with solar cars

Chapter 100 Wheels
The center of gravity is very important, especially when the center of gravity is unstable during high-speed movement, it may cause rollover.

The higher the center of gravity is not, the better. The stability of the center of gravity depends on the position of the center of gravity. A good center of gravity must be a point that ensures that the object can run smoothly.

It is still in the stage of conceptual design and scheme design, and there is no need to determine the position of the center of gravity now, because Liu Yun's plan is to put those components such as batteries and components such as engines inside the mechanical thigh, so that Effectively lower the center of gravity, commonly known as sinking.

The problem of the center of gravity is more metaphysical. It is estimated that it will take a lot of time to adjust in the future, but this is still acceptable. After all, if you want to use the mecha as a Transformer, you still have to accept this shortcoming.

The more complex the design, the more difficulties to overcome, and naturally, the more time and energy it takes.

In addition to the problem of the center of gravity, Liu Yun intends to put the wheels on the legs of the mecha 1.0, that is, under the feet, so that the effect similar to the mecha can be easily achieved, but in order to show the effect similar to the mecha The legs move in a tandem and back cycle.

It means that at the beginning, the left foot is in front and the right foot is in the back, and then the left foot is in the back and the right foot is in front. This way of walking forward alternately can imitate the way of running of human beings, which is more enjoyable to watch.

This continuous circulation of the front and rear order of the wheels can make the Mecha 1.0 different from the rigid design of the car's left and right tires in a horizontal position, which can be said to be very user-friendly.

The purpose of designing Mecha 1.0 is to go beyond the car, but to use the characteristics of the car and use the car as a prototype to design Mecha 1.0 using various mechanical principles of the car.

The mecha manufactured in this way can meet faster running, more graceful and fast running.

This can be regarded as the first step for human beings to realize mechs, which can imitate the operation methods of those Zerg aliens.

There are not many Zergs on the planet Moss, and there are even fewer Zergs legally living on the planet Moss. It can be said that there are only a few hundred Zergs legally living on the entire planet Moss.

And most of these legally living Zergs are Level 1 mantises, which belong to the lowest level of Zergs.This level 1 praying mantis is not very good in terms of attack power or defense. It is not very different from our common beasts, but its shape is rather peculiar, a bit like an enlarged version of a praying mantis. This enlarged version of a mantis is in There is definitely no such thing as Planet Moss.

It is said that Liu Yun has traveled through the planet of Huisi for so long and has not seen Zerg yet.

In fact, in 2999, there were no aliens living on the planet Reus. I don’t know if it’s because of the butterfly effect. Since Liu Yun traveled back to the previous time, there have been many differences on the planet Reus. The place.

For example, there are many legally living aliens on the planet Moss.

It has to be said that it is acceptable for aliens, aliens and humanoid groups to live in peace on the planet Moss, but because the differences between races are too great, various conflicts between aliens and humans often occur.

Fortunately, aliens are generally more restrained, and don't care much about causing trouble on the planet Moss.Because it is very difficult for aliens to obtain the legal right to live on the planet Moss, most of the aliens have obtained a residence permit to live on the planet Moss after 81 or [-] difficulties, so they are naturally reluctant to go It's a death, and the result of the death is likely to be the cancellation of the legal right to live on the planet Moss.

Once the legal right of residence of aliens is deprived, it means that aliens will not be able to appear in public places in a fair manner. Even if they cannot appear in public places, many places with people are not allowed to go. It is very easy. exposed.

The result of the exposure was naturally reported, and then expelled from the planet Moss.

For these aliens who like to enjoy themselves on the planet Moss, they are unwilling to go back to the original planet and live the life of eating raw meat and drinking dirty water all day long. Life on the planet Moss is still comfortable. Delicious vegetables and all kinds of meat are available. It can be said that the product resources are extremely rich, which is why the aliens want to enter the planet Moss even if they sharpen their heads.

Without him, the life on Planet Moss is so cool, at least there is no need to worry about eating and drinking, which is far from comparable to those planets with poor civilization.

Especially those Zergs are even more reluctant to return to the original planet. When they were on the original planet, these level 1 mantis insects were basically hungry all day long. It can be said that eating one meal a day is considered good. Ordered, sometimes not able to eat a meal for several days.

Then look at the planet Moss, as long as you are willing to work, you can easily earn 100 yuan, which is enough to buy several catties of live grasshoppers to satisfy your hunger. Stars don't like it.

It's a pity that the management of aliens on the planet Muse is relatively strict, and not everyone can legally stay on the planet Muse.

Liu Yun has not seen any aliens so far, and he must meet aliens if he has the opportunity.

At present, Liu Yun has no time. At present, the focus of Liu Yun's work is to manufacture mechas, but he doesn't have so much free time to do other things.

I just finished talking about the wheels. Liu Yun plans to put the wheels at the bottom of the Mecha 1.0 version. Since the Mecha 2.0 version will castrate the tires and simply use the two legs of the Mecha to run, so when designing the Mecha 1.0 You have to use small wheels, not those very visible tires.

If you use the tires of a car, it won't be a car.

Liu Yun's idea is to put a turntable under the 1.0 mecha, hang many small round wheels on the turntable, and control the direction of the mecha 1.0 by manipulating the wheels under the turntable.When the 2.0 version of the mecha is released, the turntable under the mecha is castrated, so that the 2.0 mecha can truly imitate human actions.

Mecha version 1.0 slides on the ground through the small wheels under the turntable. The friction between the round wheels and the ground is smaller, and it is easier to reduce the resistance of progress.

As for the material of the wheels on the turntable, Liu Yun plans to use 304 material directly as the small wheels under the turntable.

The shape of the wheel can be round, which is the ball shape of a football star, or it can be flat and round like a car tire.

In fact, there is not much difference between these two types of wheels, but the small ball of the star is relatively easier to change, because the ball of the star does not need to adjust the direction when it is convenient to change, and the flat circle needs to turn when changing the direction. Just a click.

The flat, circular wheels need to change direction first in order for the mech to go in a certain direction.
