Hi everyone, my name is Junhao Yu. I can tell from the name that I am from China and I live in Brooklyn now. My major is mechanical engineering, and I like it very much. This comes from my dream when I was very young. About 5 years ago, I taught myself to assemble a racing drone. This is a dream I wanted to achieve when I was in the fifth grade of elementary school. Fortunately, I realized it. When I first had this idea, I didn’t even know the name of each component. Then I looked for information on the Internet bit by bit to learn the role and working principle of each component of the drone. At the same time, I also love to play games and stay at home.
