Building is an essential part of creating the robot. This is because builders will have to physically build the robot, while following the CAD model of the design. As builders, we are provided with many parts and tools to help create our ideas to reality, and along with that we work together as a team. Although the CAD Model is the 3D blueprint of the design, a key element that is always essential to building is problem-solving. If something went wrong, builders will have to improvise and use the power of problem-solving to work around any complications or difficulties.
