This project combines hardware assembly, 3D printing, and flight tuning into a compact soccer drone. The design focuses on a protected outer shell, beginner-friendly control, and a small footprint that can survive closer contact than a bare racing quad.

Voi mot nhom hoc sinh, bai toan khong chi la lap cho bay duoc, ma con phai giu chi phi hop ly va de sua khi co va cham. A small soccer-style drone needs to be light, durable, and easy to orient in flight. For a student team, the challenge was not just making it fly, but also keeping the build affordable, repairable, and safer during contact.

We built around the SpeedyBee F405 AIO V2, LANNRC 1404 Plus motors, ELRS 2.4GHz control, a 3D-printed inner frame, and a protective outer soccer shell. The drone uses orientation LEDs, a Tattu 3S battery, and Betaflight tuning to improve direction control, response, and overall balance.
