Engineer Joshua Bird has developed a single-motor drone featuring a 3D-printed frame. Unlike traditional rotary-wing aircraft that utilize swashplates or secondary propellers for stability, this design manages torque and directional control by modulating motor speed. The drone relies on a 45-degree hinged rotor system where blades pivot during acceleration to adjust pitch and roll.
To achieve yaw control, the project integrates motor adjustments with 3D-printed stabilizing fins. During the development process, the creator utilized a custom high-speed camera setup, consisting of a Sony camera and a microcontroller, to identify issues with propeller rigidity. This led to the replacement of initial components with sturdier 3D-printed parts.
Initial flight testing took place in a bedroom environment, utilizing an IR beacon for navigation. While current flight capabilities are restricted to this setup, the developer plans to integrate a linear camera to enable operations in other environments. The project documentation and source code are available via a GitHub repository.
