Optimizing Terrain Mapping and Landing Site Detection for Autonomous UAVs
Pedro F. Proença, Jeff Delaune, Roland Brockers
The next generation of Mars rotorcrafts requires on-board autonomous hazard avoidance landing. To this end, this work proposes a system that performs continuous multi-resolution he…
Mid-Air Helicopter Delivery at Mars Using a Jetpack
Jeff Delaune, Jacob Izraelevitz, Samuel Sirlin +32
Mid-Air Helicopter Delivery (MAHD) is a new Entry, Descent and Landing (EDL) architecture to enable in situ mobility for Mars science at lower cost than previous missions. It uses…
Range-Visual-Inertial Odometry: Scale Observability Without Excitation
Jeff Delaune, David S. Bayard, Roland Brockers
Traveling at constant velocity is the most efficient trajectory for most robotics applications. Unfortunately without accelerometer excitation, monocular Visual-Inertial Odometry (…
xVIO: A Range-Visual-Inertial Odometry Framework
Jeff Delaune, David S. Bayard, Roland Brockers
xVIO is a range-visual-inertial odometry algorithm implemented at JPL. It has been demonstrated with closed-loop controls on-board unmanned rotorcraft equipped with off-the-shelf e…
Long-Duration Fully Autonomous Operation of Rotorcraft Unmanned Aerial Systems for Remote-Sensing Data Acquisition
Danylo Malyuta, Christian Brommer, Daniel Hentzen +3
Recent applications of unmanned aerial systems (UAS) to precision agriculture have shown increased ease and efficiency in data collection at precise remote locations. However, furt…
Disturbance Estimation and Rejection for High-Precision Multirotor Position Control
Daniel Hentzen, Thomas Stastny, Roland Siegwart +1
Many multirotor Unmanned Aerial Systems applications have a critical need for precise position control in environments with strong dynamic external disturbances such as wind gusts…
