VDM-based navigation for Delta-wing UAVs: Models, calibration, implementation
Autonomous navigation of small UAVs is typically based on the integration of inertial navigation systems (INS) together with global navigation satellite systems (GNSS). However, GNSS signals can face various forms of interference affecting their continuous ...
EPFL2024VDMNav: Software Architecture for Aerodynamically Constrained Navigation on Small Fixed-Wing Drones
Jan Skaloud, Gabriel François Laupré
Navigation of drones is predominantly based on sensor fusion algorithms. Most of these algorithms make use of some form of Bayesian filtering with a majority employing an Extended Kalman Filter (EKF), wherein inertial measurements are fused with a Global N ...
2024Performance and accuracy of cross‐section tracking methods for hydromorphological habitat assessment in wadable rivers with sparse canopy conditions
Giovanni De Cesare, Paolo Perona, Robin Schroff
This article investigates the performance and accuracy of continuous Real-Time Kinematic (RTK) Global Navigation Satellite System (GNSS) position tracking for hydromorphological surveys, based on a comprehensive river restoration monitoring campaign. The a ...
2024Aerodynamic modeling of a delta-wing UAV for model-based navigation
Jan Skaloud, Pasquale Longobardi
This study aims to identify an optimal, as well as practical, parametric structure for a delta-wing UAV aerodynamic model for the purpose of model-based navigation. We present a comprehensive procedure for characterizing the aerodynamics of this platform, ...
2024TSLAM: a tag-based object-centered monocular navigation system for augmented manual woodworking.
TimberSLAM (TSLAM) is an object-centered, tag-based visual self-localization and mapping (SLAM) system for monocular RGB cameras. It was specifically developed to support a robust and augmented reality pipeline for close-range, noisy, and cluttered fabrica ...
2024Avoidance of Concave Obstacles Through Rotation of Nonlinear Dynamics
Controlling complex tasks in robotic systems, such as circular motion for cleaning or following curvy lines, can be dealt with using nonlinear vector fields. This article introduces a novel approach called the rotational obstacle avoidance method (ROAM) fo ...
Piscataway2024Identifying aerodynamics of small fixed-wing drones using inertial measurements for model-based navigation
Jan Skaloud, Gabriel François Laupré
The success of drone missions is incumbent on an accurate determination of the drone pose and velocity, which are collectively estimated by fusing iner- tial measurement unit and global navigation satellite system (GNSS) mea- surements. However, during a G ...
