Zwanenburg, Andreas (author)These days, people see more and more applications for drones, including monitoring rainforests to protect plant and animal species. However, drones face challenges when navigating through the dense and cluttered vegetation of the forest. These environments necessitate advanced autonomous detection and navigation to make the drone traverse...master thesis 2024

Wu, Siyuan (author)Recent progress in multiple micro aerial vehicle (MAV) systems has demonstrated autonomous navigation in static environments. Yet, there are limited works regarding the autonomous navigation of multiple MAVs in dynamic and unknown environments. The challenge arises from the complexity of the motion planning problem, which requires the MAVs to...master thesis 2023

den Ridder, Luc (author)Although deep reinforcement learning (DRL) is a highly promising approach to learning robotic vision-based control, it is plagued by long training times. This report introduces a DRL setup that relies on self-supervised learning for extracting depth information valuable for navigation. Specifically, a literature study is conducted to investigate...master thesis 2023

Casini, S. (author), Cervone, A. (author), Monna, G.L.E. (author), Gill, E.K.A. (author)Line-of-Sight (LoS) navigation is an optical navigation technique that exploits the direction to visible celestial bodies, obtained from an onboard imaging system, to estimate the position and velocity of a spacecraft. The directions are fed to an estimation filter, where they are matched with the actual position of the observed bodies,...journal article 2023

Mosab Ahmed Elsadig Diab, Mosab (author)Autonomous agents are the future of many services and industries such as delivery systems, surveillance and monitoring, and search and rescue missions. An important aspect in an autonomous agent is the navigation system it uses to traverse the environment. Not much emphasis has been paid in the past on autonomous agent navigation in cluttered...master thesis 2022

van Oorschot, Marijn (author)Spacecraft navigation and control is difficult in deep space operations. Especially around asteroids, the irregular gravity field increases the difficulty of estimating the spacecraft trajectory. Autonomous navigation can increase the safety and accuracy for orbit proximity operations. Furthermore, it eliminates the need for continuous...master thesis 2022

van der Heijden, Lars (author)Missions to small bodies are increasingly gaining interest as they might hold the secrets to our solar system’s origin while some are also posing a threat to life on Earth. The small size and irregular shape result in complex dynamics complicating the close-proximity operations. Furthermore, due to the long round-trip time communication delays...master thesis 2022

de Vos, J. (author), Pruyn, J.F.J. (author), Hekkenberg, R.G. (author)Autonomous ships have become a topic of interest for an increasing number of researchers over the last few years. Most of the research that is being performed focuses on autonomous navigation. An important driver for this research is the belief that autonomous navigation will increase safety at sea. In order to evaluate the possible safety...conference paper 2022

Colling, A.P. (author)The research in this thesis is a viability study of a waterborne platooning concept called the Vessel Train (VT). This manuscript describes the VT characteristics. It explains how the VT’s advantages are reaped, as well as the VT’s challenges that need to be considered and dealt with. To assess the potential of the platooning concept an inland...doctoral thesis 2021

Kooij, C. (author), Hekkenberg, R.G. (author)Recently, autonomous ships have gotten a lot more attention both in the media and in research. However, very little research has focussed on the effects of automation on the size of the crew. This paper analyses the effects of added automation on the required size and composition of the crew on a 750 TEU short sea container vessel. A Crew...journal article 2020

McGuire, K.N. (author)Pocket drones, weighing less than 50 grams, are small, agile and inherently safe. This makes them suitable for several surveillance tasks such as search and rescue, green-house monitoring and pipe-line inspection. In order for a more efficient search, a swarm of pocket drones would be ideal to explore these types of areas faster. Current methods...doctoral thesis 2019

Lin, Jiahao (author)Safe navigation in unknown environments is a challenging task for autonomous Micro Aerial Vehicle (MAV) systems. Previous works generally avoid obstacles by assuming that the environment is static. The purpose of this thesis work is to develop a MAV system that can navigate autonomously and safely in dynamic environments. We present an onboard...master thesis 2019

Kisantal, Máté (author)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...master thesis 2018

Lee, Seong Hun (author)We propose a novel method to deal with the scale ambiguity in monocular SLAM based on control stability. We analytically show that (1) using unscaled state feedback from monocular SLAM for control can lead to system instability, and (2) there is a unique linear relationship between the absolute scale of the SLAM system and the control gain at...master thesis 2017
