This project is a proof-of-concept prototype of a low-cost rocket launcher and guided rocket system built using consumer electronics and 3D-printed components. The rocket uses folding fins and canard stabilization controlled by an onboard ESP32 flight computer and MPU6050 inertial measurement unit, while the launcher integrates sensors such as GPS, compass, and barometric modules for orientation and telemetry. The system was designed in Fusion 360, simulated using OpenRocket, and developed through iterative mechanical, electronics, and launch testing. The total hardware cost of the prototype is approximately $96.
