Real-Time Collision-Free Navigation of Multiple UAVs Based on Bounding Boxes [PDF]
Electronics, 2020 Predictably, future urban airspaces will be crowded with autonomous unmanned aerial vehicles (UAVs) offering different services to the population. One of the main challenges in this new scenario is the design of collision-free navigation algorithms to avoid conflicts between flying UAVs.

Distributed integral control of multiple UAVs: precise flocking and navigation [PDF]
IET Control Theory & Applications, 2019 The authors interest in this work is to perform a precise real‐time flocking of multiple unmanned aerial vehicles (UAVs). A consensus‐based flocking algorithm that ensures a precise security distance between UAVs is proposed. By using Lyapunov theoretical analysis, the authors propose a flocking algorithm that ensures the ultimate boundedness of ...

Autonomous navigation for multiple unmanned aerial vehicles (UAVs) in urban environments
MATEC Web of Conferences, 2023 This paper presents an autonomous navigation system for multiple unmanned aerial vehicles (UAVs) in urban environments. The navigation system comprises a long-term route planner and a short-term cooperative collision avoidance function. A 3D model of a real urban terrain is used to represent the environment within which the UAVs operate, and the system

Multiple UAVs Three-Dimensional Navigation Using a Hybrid Optimization Algorithm
, 2022 Abstract This paper aims to propose a hybrid approach for multiple UnmannedAerial Vehicle navigation. This is an NP-hard problem since the robots have to find the optimal safe path without colliding with other robots and obstacles in three-dimensional search space.

A Real-Time Flight Safety Alarm System for Multiple UAVs [PDF]
MATEC Web of Conferences, 2019 Airborne heterogeneous UAVs can encounter flight control or sensor failures while performing flight tasks. To protect against this, safety alarm systems (SAS) are typically implemented in ground control systems (GCS) to prevent crashes or other failures.

Electronics, 2023 Navigation relayed by multiple stations (NRMS) is a promising technique that can significantly extend the operational range of unmanned aerial vehicles (UAVs) and hence facilitate the execution of long-range tasks. However, NRMS employs multiple external stations in sequence to guide a UAV to its destination, introducing additional variables and ...
