VEX educational robot originated in the United States, and is often called the VEX robotics World Championship held in the United States every April. This is one of the most important youth robot competitions in the world. Every year, elite players from more than 60 countries are selected to participate in this competition. VEX educational robots encourage children to design and program robots freely by assembling various robot parts by hand. In this series of processes, they learn different mechanical parts, understand the basic knowledge of machinery, and fully study and apply various electronic sensors, involving the knowledge of science, technology, engineering, mathematics and other comprehensive disciplines. At the same time, VEX robotics mainly adopts PBL project production learning mode. Children learn robots more in the form of group challenges, and fully learn robot knowledge in the process of constantly asking questions, discussing problems, solving problems and constantly improving, which is also an important exercise for children's critical thinking and innovative thinking. Regarding training, I know that the official VEX College is specially set up for domestic children. You can go to their website to find out.
