Although solar energy, robot production, and batteries are all high-tech, if you want to do something relatively elementary, it is still very easy and does not require much technological content. Take solar energy as an example. If you want to make a solar water heater, it is easy. Just find an iron box and connect the pipes. However, it is very difficult to make a solar battery with high energy efficiency (the world has not yet overcome this problem. , haha, the current material science has not reached that level yet), the same goes for robots. It is not difficult to make a robot. It is just a bunch of parts combined together in an orderly manner through your creativity to realize the function. Find a battery and make it. A motor, you can just use a fuel engine instead of a motor, a bunch of transmission rods, you can make it with a little more effort, and you don’t need to be highly educated, but it will be difficult to make a robot with artificial intelligence (currently still under research stage, mainly because the computer chips used today have not yet made a qualitative leap), and batteries are also very easy. I remember that when I was in high school, it seemed that it was quite simple to do experiments. I made some copper sulfate wires or something, but the energy efficiency of fuel cells It has never been completely perfected, otherwise today's cars would no longer need to burn oil.
Let me introduce you to two people:
1. Chen Xide, a former ordinary worker in Shanghai Construction Machinery Factory, (junior high school education), his family was labeled as a counter-revolutionary during the Cultural Revolution, he worked hard to study solar energy Technology, he built the first solar water heater in 1972 and China's first high-temperature solar furnace in 1979. He entered the Shanghai Energy Research Institute in 1980 and was received by President Li Xiannian in 1981. In 1984, he was invited to the United States by an American company. In 1990, he went to Thailand to start a business with his own solar water heater technology and founded Xide Water Heater Company. He registered more than a dozen patents and returned to China for development after 2005.
2. Wu Yulu, an ordinary farmer in Tong County, Beijing, (primary school education), has been researching and making robots independently since he was young. In 1978, he built a robot that can walk independently, called Boss Wu, and later built a robot that can climb walls. Wu Lao San, Wu Lao San who can serve tea and pour water, speak and write calligraphy, Wu Lao Qi, the octagonal monster, Wu Lao 25 ??who can pull a rickshaw, etc., there are 26 robots. Among them, Super Wu Laowu: can walk, can pour tea and water, can write calligraphy, can sense people within 2 meters and speak (can move his eyes and mouth) to say hello, was bought by the Institute of Robotics of the Chinese Academy of Sciences for 100,000 yuan, Wu Yulu now often He has been invited to science exhibitions in various places and is also a member of the Chinese Association of Science and Technology. Many of his patented robots have been purchased at high prices and put into practical use
So work hard.
