Airborne sensor fusion: Expected accuracy and behavior of a concurrent adjustment
Jan Skaloud, Davide Antonio Cucci, Aurélien Arnaud Brun, Kyriaki Mouzakidou
Tightly-coupled sensor orientation, i.e. the simultaneous processing of temporal (GNSS and raw inertial) and spatial (image and lidar) constraints in a common adjustment, has demonstrated significant improvement in the quality of attitude determination wit ...
2024Soft Robot Shape Estimation With IMUs Leveraging PCC Kinematics for Drift Filtering
Josephine Anna Eleanor Hughes, Francesco Stella
The control possibilities for soft robots have long been hindered by the need for reliable methods to estimate their configuration. Inertial measurement units (IMUs) can solve this challenge, but they are affected by well-known drift issues. This letter pr ...
Piscataway2024VDMNav: 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 ...
2024VDM-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 ...
EPFL2024Into the ice: Exploration and data capturing in glacial moulins by a tethered robot
Josephine Anna Eleanor Hughes, Max Mirko Polzin
Glacial moulins (cylindrical meltwater drainage shafts) provide valuable insights into glacier dynamics, but are inaccessible and hazardous environments for humans to study. Exploring them using passive sensor probes has revealed their complex geometry, wh ...
Hoboken2024Lumped Drag Model Identification and Real-Time External Force Detection for Rotary-Wing Micro Aerial Vehicles
Alcherio Martinoli, Lucas Cédric Wälti
This work focuses on understanding and identifying the drag forces applied to a rotary-wing Micro Aerial Vehicle (MAV). We propose a lumped drag model that concisely describes the aerodynamical forces the MAV is subject to, with a minimal set of parameters ...
2024Model-based constraints for trajectory determination of quad-copters: Design, calibration & merits for direct orientation
Jan Skaloud, Davide Antonio Cucci, Kenneth Joseph Paul
This paper proposes a novel method to improve georeferencing of airborne laser scanning by improved trajectory estimation using Vehicle Dynamic Model. In Vehicle Dynamic Model (VDM), the relationship between the dynamics of the platform and control inputs ...
