Kilometer-Scale GNSS-Denied UAV Navigation Via Heightmap Gradients: A Winning System from the SPRIN-D Challenge

ICRA 2026poster

Reliable long-range flight of unmanned aerial vehicles (UAVs) in GNSS-denied environments is challenging: integrating odometry leads to drift, loop closures are unavailable in previously unseen areas and embedded platforms provide limited computational power. We present a fully onboard UAV system de…

Timepix Radiation Detector for Autonomous Radiation Localization and Mapping by Micro Unmanned Vehicles

IROS 2019poster

A system for measuring radiation intensity and for radiation mapping by a micro unmanned robot using the Timepix detector is presented in this paper. Timepix detectors are extremely small, but powerful 14 × 14 mm, 256 × 256 px CMOS hybrid pixel detectors, capable of measuring ionizing alpha, beta, g…

Model Predictive Trajectory Tracking and Collision Avoidance for Reliable Outdoor Deployment of Unmanned Aerial Vehicles

IROS 2018poster

We propose a novel approach for optimal trajectory tracking for unmanned aerial vehicles (UAV), using a linear model predictive controller (MPC) in combination with non-linear state feedback. The solution relies on fast onboard simulation of the translational dynamics of the UAV, which is guided by…
