van den Bergh, Michael (author)Energy harvesters subtract energy from their surroundings and convert this to electrical energy. Even though energy output is generally low, energy harvesters can offer great value by offering the possibility of self-sustaining devices, combined with the developments in low power semiconductors. Many examples can be found of applications that...master thesis 2023

van der Wielen, Matthijs (author)The use of optical fibres as distributed vision sensor within a contactless handling system is discussed in this study. The three primary light colours and a volume diffuser will be used to detect the edge of an object levitating on an air-bearing table. One building block of a bigger system is used that consists of one receiving fibre in the...master thesis 2022

Solot, Elke (author)Hexapod robots are becoming increasingly popular for navigating and exploring irregular and inhospitable environments. The Lunar Zebro is such a hexapod robot that has been developed to be the lightest and smallest rover to explore the moon. The purpose of the Lunar Zebro is to navigate the surface of the moon where it will encounter difficult...master thesis 2022

Suurveld, Martijn (author)Over the past decades Minimally Invasive Surgery (MIS) has become a standard in abdominal surgery. Due to limited dexterity and bad ergonomics the field of MIS is shifting towards Robot-Assisted MIS (RAMIS). Simultaneously, the field is using increasingly small and steerable instruments to reduce invasiveness. Surgeon now work with fragile...master thesis 2022

van Rijn, Jan (author)Remotely controlled vehicles have gained increased interest and application, like the exploration of inhospitable environments. To this end hexapods with C-shape locomotors are particularly suitable because these vehicles possess both the efficiency of wheels and the climbing capabilities of legged robots. Currently all C-legged hexapods are...master thesis 2022

Treurniet, Daan (author)The work presented in this report is an attempt to allow density-based topology optimization algorithms to take into account machining costs when optimizing. To this end, and estimation model for the cost of 2.5-axis CNC milling was developed based on the principles of Design for Manufacturing.<br/>This estimation model was implemented in a...master thesis 2021

Spruit, Jan Willem (author)In this thesis the design possibilities to replace a Lavet-type motor with an electrostatic motor are investigated. At the moment, almost all quartz watches use a Lavet type of motor. Two electrostatic conceptual designs are made by Timex and Accutron. An electrostatic motor for the watch application looks promising due to the more efficient...master thesis 2021

Roulaux, Bas (author)Flapping-Wing Air Vehicles (FWAV) are autonomously flying vehicles that use their flapping wings to simultaneously stay aloft and enable controllable flight. FWAVs that are capable of controllable flight are reported in literature, though a theoretical background of the aerodynamic performance of different attitude control mechanisms is absent...master thesis 2021

Fritz, Arnout (author)With the ever-increasing demand for a more efficient production process, the thickness of silicon wafers for the solar cell industry has shown a decreasing trend over the years. This makes the substrates more and more fragile, with an increasing breakage rate as a result. Research at the TU Delft has been done on contactless handling, using air...master thesis 2021

Mous, Guido (author)In recent years, an increasing amount of research projects contributed to the development of flapping-wing-micro-aerial-vehicles (FWMAV) that can fly and perform hovering flight in confined spaces. However, scaling laws have a negative influence on the aerodynamic efficiency and actuator efficiency. Consequently, FWMAVs suffer from very limited...master thesis 2020

Suresh Subramonian, Jishnu (author)The most simplistic acts in nature can be incredibly complex to replicate. Among which, insects in general, are profound micro-machines with evolution as the backbone for their most optimized features. This study focuses on developing an efficient sensing and processing strategy for autonomous flight maneuvers in Atalanta, a bio-inspired robotic...master thesis 2020

Narayanan, Anirudh (author)The goal of this study is to understand the processes and wing characteristics that influence lift generation of a flapping wing, and apply the acquired knowledge in an optimization setting to obtain an optimal wing thickness distribution which maximizes effective wing lift. To achieve this, an extensive literature survey was conducted to...master thesis 2019

van Munster, Ewoud (author)Large multi-object spectroscopy telescopes measure the light from millions of stars and galaxies for the use in astronomical studies. One part of these telescopes is the fiber positioner, where a few thousand of optical fibers need to be individually positioned very accurately. The problem with current fiber positioners is the small patrol area,...master thesis 2018

Swuste, Rolf (author)The Atomic Force Microscope (afm) is a small scale measuring device, with a lot of benefits over other existing measuring techniques. Unfortunately, measurement speed is not one of them. Many have tried and succeeded to improve the measurement speed, but there is still room for improvement.<br/>By passively lowering the Q-factor, a measurement...master thesis 2017
