The invented anti-collision stroller was invented by Liu Jie, a junior 3 student of Zhuge Middle School in Xiangyang, Hubei. This little invention, which is very practical and helpful to real life, is actually inspired by the low-headed people in life. Many parents or elders are actually negligent when taking care of their children. For example, when pushing a stroller, it is actually easy to get distracted. For example, when waiting for the traffic lights, they will take out their mobile phones and start killing time. At this time, their attention is not on the stroller, but on the mobile phone. So many accidents may happen at this time, so the security risk will also increase.

In view of this common social phenomenon, Liu Jie, a junior high school student in Xiangyang, invented this intelligent anti-collision stroller according to this phenomenon. In fact, in real life, we can also solve many problems and avoid some risks. Its principle is that when the stroller collides with an obstacle, the brake pad will automatically fall down to achieve the purpose of automatic braking. Besides automatic braking, the invention can also effectively prevent collision, so that children in the stroller can be protected to a great extent.

This invention has a wide range of knowledge, including programming, 3D printing, laser engraving and circuit knowledge. For a junior high school student, it covers such a wide range of knowledge that many people are amazed. In fact, the important thing is not to know something about this knowledge, but to apply what you have learned, so that junior high school students can master the knowledge in their minds. And apply it to real life, so as to invent such a practical thing, which is also of great help to people's daily life.

Liu Jie's invention is to apply what he has learned, so he is also an example to many students. We should not only learn the knowledge from books, but also apply it to practice.
