Introduction:

Building upon the initial design's success, the second version features a robust 600mm carbon fiber frame and arms tailored for a 2kg quadcopter. This upgraded frame is capable of lifting a payload of up to 500g, making it ideal for delivering essential supplies in emergency scenarios. The frame incorporates a customized power distribution board designed for the Pixhawk Cube, supporting both auxiliary and main outputs for efficient power management. Additionally, the folding arms ensure compact storage and easy transport, crucial for deployment in remote or disaster-stricken areas. The drone utilizes 12–13 inch propellers paired with 620 KV Tarot BLDC motors, providing optimal flight performance and stability. Guided by Mission Planner software, the seamless integration of these components guarantees precise operation and mission execution, further advancing open-source drone solutions for global disaster response efforts.
