An Innovative Algorithm to Estimate Risk Optimum Path for Unmanned Aerial Vehicles in Urban Environments

Autonomous Exploration in Unknown Urban Environments for Unmanned Aerial Vehicles

In this paper, we present an autonomous exploration method for unmanned aerial vehicles in unknown urban environment. We address two major aspects of explorationmap building and obstacle avoidanceby combining model predictive control (MPC) with a local obstacle map builder. An onboard laser scanner is used to build the online map of obstacles around the vehicle during the flight. A real-time MP...

unmanned aerial Vehicles : an Overview

j a n u a r y / f e b r u a r y 2 0 0 8 www.insidegnss.com Once we tried to Google “UAV” and got more than two million citations on the Internet. Try to find the definition of unmanned aerial vehicle (UAV) and you’ll uncover a welter of choices in the literature. So, let’s just say that a UAV is an aerial vehicle capable of sustained f light without the need for a human operator onboard. Althou...

Robust Trajectory Planning for Unmanned Aerial Vehicles in Uncertain Environments

As unmanned aerial vehicles (UAVs) take on more prominent roles in aerial missions, it becomes necessary to increase the level of autonomy available to them within the mission planner. In order to complete realistic mission scenarios, the UAV must be capable of operating within a complex environment, which may include obstacles and other no-fly zones. Additionally, the UAV must be able to overc...

3D Obstacle Avoidance in Adversarial Environments for Unmanned Aerial Vehicles

As unmanned aerial vehicles (UAVs) are considered for a wider variety of military and commercial applications, the ability to navigate autonomously in unknown and hazardous environments is increasingly vital to the effectiveness of UAVs. Reliable and efficient obstacle detection is a fundamental prerequisite to performing autonomous navigation in an unknown environment. Traditional two-dimensio...
