The project involved designing, assembling, and testing a rocket with 3D printed components. Key aspects included developing an ignition system with a seven-segment display, achieving attitude stabilization with fins, and recovering flight and video data. Testing of the rocket engine and structure was performed using simulation software like ANSYS and OpenRocket. Sensor fusion and PID control were used to measure flight motion and manipulate fin angles for stability.
