This ambitious project aims to revolutionize drone technology by creating a lightweight, cost-effective, and programmable drone. The drone is designed to be controlled through a Software Development Kit (SDK), making it highly versatile and adaptable to various applications. By leveraging sophisticated technology and innovative design principles, this drone sets new benchmarks in drone performance and functionality.
Serves as the central processing unit, managing computations and communications effectively.
Captures comprehensive data on the tracker's spatial orientation and movement, ensuring precise activity tracking.
Guarantees optimal power management, a pivotal feature for the device's operational longevity.
The drone's structure ingeniously expands upon the Printed Circuit Board (PCB) itself, contributing to its lightweight and compact form.
I2C and SPI communication paths are meticulously designed with matched impedance, ensuring high-speed data transfer and operational integrity.
Careful analysis of electromagnetic interference and noise generated by motors leads to the implementation of analog filters, guaranteeing a stable power supply to the MCU and sensors.
The power lines of the PCB are robustly designed to handle a maximum current of 15 Amps, accommodating the drone's dynamic power requirements.
Incorporated within the circuit, this charger facilitates the recharging of the LiPo battery, the drone's primary power source.
Developed to expedite data reading, with special enhancements like overclocking the I2C line for optimal performance.
The system boasts six simultaneously running cascaded Proportional-Integral-Derivative (PID) controllers, meticulously maintaining the drone's position and stability.
A significant breakthrough in this project is the optimization of wireless communication and flight control loop codes within the same MCU. This optimization ensures that the flight control loop maintains its critical constant rate, unaffected by potential delays in wireless communication.
Unlike conventional drones that typically use separate ICs for wireless communication and flight control to prevent interference, this drone harmoniously integrates both functions within a single MCU. This integration not only conserves space and reduces weight but also enhances the efficiency and responsiveness of the system.
