abstract = {Data underlying the publication: MonoRACE: Winning Champion-Level Drone Racing with Robust Monocular AI This dataset supports the publication “MonoRACE: Winning Champion-Level Drone Racing with Robust Monocular AI” . The research investigates robust autonomous high-speed drone racing using a single forward-facing monocular camera and an onboard IMU, with the goal of enabling reliable gate detection, state estimation, and control during aggressive flight. The dataset contains flight-log data from eight autonomous drone racing flights, providing experimental data collected during the development and evaluation of the MonoRACE system. The flight logs contain onboard sensor and flight-control data used to analyse the behaviour and robustness of the system during racing. In addition to the flight data, the dataset includes the software components used in the experiments: the MonoRaceGate implementation for monocular gate-based navigation, the INDIFlight flight-control software, and the Optimal Quad Control reinforcement-learning controller developed for the A2RL 2025 autonomous drone racing competition. These components provide the research and implementation context needed to interpret and potentially reuse the data. The dataset therefore combines experimental flight logs with source code for the perception, navigation, reinforcement-learning control, and low-level flight-control components used in the research.},

The flight logs contain onboard sensor and flight-control data used to analyse the behaviour and robustness of the system during racing. In addition to the flight data, the dataset includes the software components used in the experiments: the MonoRaceGate implementation for monocular gate-based navigation, the INDIFlight flight-control software, and the Optimal Quad Control reinforcement-learning controller developed for the A2RL 2025 autonomous drone racing competition. These components provide the research and implementation context needed to interpret and potentially reuse the data. The dataset therefore combines experimental flight logs with source code for the perception, navigation, reinforcement-learning control, and low-level flight-control components used in the research. |

abstract = {Medium altitude, long endurance unmanned aerial systems such as Shahed-type strike drones are an unanswered threat in modern conflicts. Conventional air defense systems are too expensive to provide a feasible large-scale solution. Quadcopter interceptors are a cheap, battle-proven alternative, but their extremely limited flight time restricts them to low altitude targets at short range, whereas fixed-wing platforms have the endurance to reach higher altitude targets from longer distances. However, such interceptors are still operated manually. Recent developments in learning-based controllers show potential for automation. In this work, a fixed-wing interceptor is presented that is controlled by a neural network that maps filtered monocular vision observations directly to actuator commands. The policy was trained in a custom Python environment using reinforcement learning and proximal policy optimization. The policy was then deployed on a fixed-wing platform and tested in real interception scenarios. As a baseline, two classical guidance controllers were also developed and tested in simulation. The policy is able to intercept targets both in simulation and in real flight. In simulation, the policy outperforms the classical controllers under most conditions. The interceptor was ultimately successfully validated in real flight by intercepting maneuvering fixed-wing targets.

Medium altitude, long endurance unmanned aerial systems such as Shahed-type strike drones are an unanswered threat in modern conflicts. Conventional air defense systems are too expensive to provide a feasible large-scale solution. Quadcopter interceptors are a cheap, battle-proven alternative, but their extremely limited flight time restricts them to low altitude targets at short range, whereas fixed-wing platforms have the endurance to reach higher altitude targets from longer distances. However, such interceptors are still operated manually. Recent developments in learning-based controllers show potential for automation. In this work, a fixed-wing interceptor is presented that is controlled by a neural network that maps filtered monocular vision observations directly to actuator commands. The policy was trained in a custom Python environment using reinforcement learning and proximal policy optimization. The policy was then deployed on a fixed-wing platform and tested in real interception scenarios. As a baseline, two classical guidance controllers were also developed and tested in simulation. The policy is able to intercept targets both in simulation and in real flight. In simulation, the policy outperforms the classical controllers under most conditions. The interceptor was ultimately successfully validated in real flight by intercepting maneuvering fixed-wing targets. This novel system shows the potential of artificial intelligence for autonomous control of fixed-wing interceptor drones. |

abstract = {Autonomous maritime search and rescue faces critical challenges due to limited endurance and dynamic victim drift. This thesis presents a centralized multi-UAV coordination framework based on Energy-Aware Informative Path Planning. The aim is to maximize mission endurance by exploiting the distinct energy dynamics of different flight regimes, such as the efficiency of fixed-wing cruise versus the high cost of hovering. Locally, a Receding Horizon Planner optimizes the trade-off between entropy reduction and energy consumption.

Autonomous maritime search and rescue faces critical challenges due to limited endurance and dynamic victim drift. This thesis presents a centralized multi-UAV coordination framework based on Energy-Aware Informative Path Planning. The aim is to maximize mission endurance by exploiting the distinct energy dynamics of different flight regimes, such as the efficiency of fixed-wing cruise versus the high cost of hovering. Locally, a Receding Horizon Planner optimizes the trade-off between entropy reduction and energy consumption.

abstract = {Aerial robots typically treat surrounding objects as obstacles, even when some could be pushed aside. This thesis presents a vision-based active-perception framework for assessing whether an aerial robot has sufficient force to push an unknown object. The framework includes an uncertain outcome to indicate when visual estimates do not support a definite decision and physical probing would be needed; executing physical probing and pushing is outside the scope of this work. Pushability is modeled relative to the robot's available horizontal force and the object's estimated resistance to sliding. Active multi-view voxel reconstruction estimates object volume, while material classification provides a class associated with predefined density and static-friction coefficient intervals. These estimates form a friction-force interval that, together with a material-confidence check, produces one of three outcomes: pushable, not pushable, or uncertain. In the integrated Unity evaluation, no object was incorrectly classified as pushable. However, only 10 of 22 force-feasibility decisions for objects with accepted material predictions matched the reference outcome, and six of seven reference-ambiguous objects were classified as not pushable rather than uncertain. Counterfactual analysis linked most errors to limitations in the density–friction model, with a plausible contributing explanation being the mismatch between solid-material density assumptions and the effective densities of hollow or composite objects. In Gazebo, two of eight objects received the intended decision, while three could not complete viewpoint acquisition. The framework provides a baseline for visual assessment of aerial pushing force feasibility, while the results highlight the need for more representative physical-property models, explicit treatment of volume uncertainty, and integration of physical probing.},
