Modular Design (Scalability)
Supports tricopter, quadcopter, hexacopter setups — flexible for multiple UAV applications.
Project Overview
Developing a Modular Communication System for UAVs Using Ultra-Wideband (UWB) Technology
This project focuses on the design and implementation of a modular communication system for drones using UWB technology. The system enables real-time communication between the flight controller and ESCs, overcoming traditional wiring limitations. It is suitable for advanced logistics applications and highly customizable UAV configurations.
Key Features
UWB Communication
Decawave DWM1001C @ 6489.6 MHz, 499.2 MHz bandwidth, up to 6.8 Mbps for reliable low-latency links.
Latency Optimization
End-to-end delay within ~5 ms for motor control, validated via simulation and real-world tests.
System Architecture
The architecture includes a master module that captures PWM signals from the flight controller, and multiple slave modules (each with ESC, motor, UWB receiver). Slaves synchronize motor control using PWM triggered by a master sync signal.
Performance Results
Experiments show stable flight despite introduced wireless delays. Hardware-in-the-loop simulations confirm robust control even around the 5 ms delay threshold, consistent with real-world outcomes.
