Demonstrate the physical operation of a complete robot after Lego EV3 mechanical construction and programming. Then use videos to introduce and explain the VRC (VEX Robotic Competition) and FRC (First Robotic Competition) robot world competitions, which are currently mainly for junior and high school students. Although this winter camp only starts with the basic Lego EV3 mechanical construction, letting children understand the relevant robot VRC and FRC world competitions, including the use of materials, competition regulations, and the current participation of various secondary schools in Taiwan, is also an important part of inspiring their interest.
