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.

Status: Completed

Key Features

Modular Design (Scalability)

Supports tricopter, quadcopter, hexacopter setups — flexible for multiple UAV applications.

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.

“Anything is a Drone!” — Research Context

Developed within the Embedded Systems Lab at the University of Trento (UniTrento DII), this project explores how any object can become a flying platform using modular and wireless UWB-based propulsion units. The concept eliminates traditional frames and cables — the payload itself becomes the drone’s structure.

  • Modular plug-and-play propeller units
  • Wireless communication between controller and rotors
  • Dynamic frame concept — the payload becomes the structure
  • Scalable and energy-efficient design for flexible missions
