The 70-year-old man invented a smart car that automatically climbed stairs. What do you think of the old man's invention?

A few days ago, Zhou Lao, a 70-year-old man from Huai 'an, Jiangsu Province, has invented an intelligent car that can automatically climb stairs. Compared with the size of wheelchair, this car can help some people with inconvenient legs or feet or disabled people climb stairs and pass through potholes no more than 30 cm deep. You know, there are many old people with inconvenient legs and feet in our country. Even in a wheelchair, you can't go up and down stairs. But they can only move on flat ground. Therefore, often the children of the elderly will arrange the house on the first floor or in the elevator room to facilitate the elderly to go in and out, but the stairs everywhere still hinder the actions of the elderly. Therefore, the smart car invented by Mr. Zhou Lao is undoubtedly a great boon to these old people.

According to Mr. Zhou Lao, this car is designed based on Nordic all-terrain crawler. Below the wheel is the track style, which is divided into front and back parts. If you encounter stairs, slowly climb the first half and lift the second half to the corresponding position. Moreover, the track is very wide, and the car will not easily overturn. Moreover, the car is very stable, and the old people will not feel inclined and shaking greatly when sitting on it, and the effect is quite good.

Mr. Zhou Lao applied for a national patent after the experiment was successful. On August 22nd, the Patent Office approved his application and named it? Chassis drive device of all-terrain intelligent stair climber? The invention of. There must be countless experiments behind success. Zhou Lao had built five such smart cars before, but they all failed. All scrap iron can be sold for more than 3000 yuan, which shows that the parts used by Mr. Zhou Lao are expensive. It is reported that the whole car contains more than 2,000 parts, most of which were built by Zhou Lao himself, which cost a lot of time and money.

This car has invested a lot of time, energy and money, and I don't know what price it will sell after listing, so I don't think it will be too cheap. However, this car is really a good invention for the elderly, and many elderly people with inconvenient legs and feet need to go downstairs to play outdoors, so I believe many children will buy this invention for their elderly people in the future.
