Teleoperation is by nature a deprivation of the senses, which can pose a handicap when operating in an unknown and even dynamic en- vironment. Noticing moving obstacles in such a situation can prove to be quite difficult and the UAV runs the risk of colliding with them. Previous work designed a shared control haptic interface based on the...

This research investigates and proposes a new method for obstacle detection and avoidance on quadrotors. One that does not require the addition of any sensors, but relies solely on measurements from the accelerometer and rotor controllers. The detection of obstacles is based on the principle that the airflow around a quadrotor changes when the...

Previous years have seen a rise in the use of Unmanned Aerial Vehicles (UAVs). Reaching a large endurance and range while being able to perform Vertical Take-Off and Landing (VTOL) landings allows a broad range of applications. For this purpose the DelftaCopter (DC) was developed, a tilt-body tailsitter UAV. It hovers using a single helicopter...

Deployable morphing aircraft are gaining popularity in the academic and industrial world. Their deployability offer the possibility to be stored and takes less space. This is advantageous in volume limited applications like space explorations, where every cubic centimeter is important. Another field where this aircraft is increasingly used is...

We investigate how an Unmanned Air Vehicle (UAV) can detect manned aircraft with a single microphone. In particular, we create an audio data set in which UAV ego-sound and recorded aircraft sound can be mixed together, and apply convolutional neural networks to the task of air traffic detection. Due to restrictions on flying UAVs close to...

Current unmanned aerial vehicles (UAVs) are limited in operating altitude and endurance by the maximum attainable performance of small gas turbine engines. While improvements in the cycle thermal efficiency can be obtained through the introduction of heat exchangers, the consequent increase in engine weight partially offsets the benefits gained...

Synchronization of Multi-Agent Systems (MASs) has the potential to benefit many technological
areas such as formation control for unmanned vehicles, cooperative adaptive
cruise control, and spacecraft attitude control. Information plays a crucial role in MASs:
in centralized approaches, a central node utilizes global information to...

Conventional practices of rating curve computation fall short in many aspects. They are data-intensive and are notoriously inaccurate in high-flow regimes as a result of extrapolation of low-flow curve fitting. By making use of a simple commercial UAV, a physically-based rating curve is computed that is substantiated by a detailed representation...

Conventional controllers are incapable of controlling a rotor failed quadrotor in high speed flight. In this paper, a fault tolerant controller based on Incremental Nonlinear Dynamic Inversion is proposed to control a quadrotor subjected to the loss of two rotors. A pseudoinverse is used to control the roll and pitch rate to steer the average...

Aircraft manufacturers are increasingly exploring emission-free flight or emission reduction for larger passenger aircraft. The low energy density of state-of-the-art battery technology limits the application to small, electric, fixed wing aircraft up to a flight time of approximately one hour. To overcome these limits, a combination of fuel...

High-speed autonomous flight of Micro Air Vehicles has gained much attention in recent years. However, flight in complex GPS-denied environments still poses a serious challenge. One scenario which contains these elements is drone racing, where pilots have to fly complex tracks at high speed, often in an indoor environment. In this work we...

Safe navigation in a cluttered environment is a key capability for the autonomous operation of Micro Aerial Vehicles (MAVs). This work explores a (deep) Reinforcement Learning (RL) based approach for monocular vision based obstacle avoidance and goal directed navigation for MAVs in cluttered environments. We investigated this problem in the...

UAVs(Unmanned Aerial Vehicles) have gained popularity in various fields, and many applications require the drones to perform tasks in indoor environments. One major challenge in UAV indoor guidance is the absence of accurate GPS(Global Positioning System)
signals. In this work, a novel guidance method is investigated which uses a library of...

Quadrotor UAV's have become extremely popular over the last decade, as they combine great agility with mechanic simplicity. For tasks such as area surveillance or maintaining a communication network, the deployment of multi-agent systems is required. In these scenarios, it often is necessary for the robot teams to navigate in formation while...

This thesis presents a visual route following method that minimizes memory consumption to the point that even Micro Aerial Vehicles (MAV) equipped with only a simple microcontroller can traverse distances of a few hundred meters. Existing Simultaneous Localization and Mapping (SLAM) algorithms are too complex for use on a microcontroller....

The Netherlands is a country primarily developed on coastal zones. Coastal zones are very important, since they are a source of valuable living and non-living resources for its population, and they also act as a natural protection against floods. Notably, the natural dynamics driven by the sea and the man-made actions on the land change them...

A Reinforcement Learning (RL) agent learns about its environment through exploration. For most physical applications such as search and rescue UAVs, this exploration must take place with safety in mind. Unregulated exploration, especially at the beginning of a run, will lead to fatal situations such as crashes. One approach to mitigating these...
