CAD is the cornerstone of how we operate. Error 404 designs everything in CAD first and then we custom manufacture almost one hundred percent of the robot components. Whether or not your team designs in CAD or simply models already constructed parts, CAD is an effective way to visualize and communicate your robot's design. We separate our CAD models, and therefore our physical robot, into generations. Gen 0 is a basic chassis and sometimes a prototype mechanism -- usually taken to Meet 1. Gen 1 and Gen 2 are generally our league meets and league championship. Gen 3 is Regionals and Gen 4 is Worlds.
