Lopez Romero, M.A. (author), Prieto-Arranz, Javier (author), Traver, Jose Emilio (author), Hunt, A. (author), Hassan HosseinNia, S. (author), Tejado, Ines (author), Vinagre, Blas M. (author)Ionic polymer metal composite (IPMC) actuators have promising applications in robotics and medicine in a not distance future, which will require a big knowledge in different fields, such as, manufacturing, material characterization and control theory. In this paper, frequency response of several IPMC actuators, cut from the same bulk IPMC sheet...conference paper 2018

Dialynas, G. (author), Happee, R. (author), Schwab, A.L. (author)Since the 1800s, the design of bicycles involves a mechanical linkage between the handlebar and the fork assembly. Herein, we propose an innovation, where the traditional mechanical connection between the handlebar and fork is decoupled and replaced with sensors, servomo-tors and a microcontroller allowing artificial manipulation of the bicycle...conference paper 2018

(author)To participate in the Outback Medical Express UAV Challenge 2016, a vehicle was designed and tested that can autonomously hover precisely, takeoff and land vertically, fly fast forward efficiently, and use computer vision to locate a person and a suitable landing location. The vehicle is a novel hybrid tail‐sitter combining a delta‐shaped...journal article 2018

Silva, Joao Paulo (author), de Wagter, C. (author), de Croon, G.C.H.E. (author)This paper proposes a trajectory planning and control strategy to optimally visit a given set of waypoints in the presence of wind. First, aerodynamic properties of quadrotors which affect trajectory planning and tracking performance are investigated. Blade flapping, induced and parasitic drag are derived and an extended method to identify all...journal article 2017

van der Spaa, Linda (author)Current robots consume a lot of energy. The work required for a task is generally just a tiny fraction of the total energy consumed. Most energy wastefully dissipated. Design of the 2 degree of freedom (DoF) Plugless Robot Arm shows that clever design can reduce these energy losses to a tiny remaining fraction. The Plugless Arm is designed to...master thesis 2017

van der Nolle, Rens (author)The amount of research and development in smart materials is increasing every year. These smart materials offer a solution to integrated and distributed actuation and sensing. Pressure sensors, acoustic transducers, deformable mirrors, micro-robotics and stiffness control of flapping wings are some applicationswhere these smart materials show...master thesis 2017

Klapwijk, Anna (author)The increase of data collection and analytics over the past few years the control over personal data has become an important issue. Control over data is the execution of privacy and the ability to protect the individual identity. Solutions to give consumers more control have failed in the past due to security and privacy concerns. On top of that...master thesis 2017

Vicente Melo E Carvalho Marques, Mariana (author)L1 adaptive control is a relatively new technique that attempts to tackle the robustness shortcoming of the MRAC controller by applying a low pass filter to the control input. It can be used as an augmentation loop using baseline controllers such as backstepping or PID. This controller has been implemented as an augmentation loop with both these...master thesis 2017

de Wagter, C. (author), Smeur, E.J.J. (author)This work investigates the design parameters and their consequences in the control of a helicopter rotor combined with a pair of fixed wings. This hybrid vehicle has a light and aerodynamically efficient rotor with a large range of pitch angles to enable both hover and forward flight. Because of the light stiff rotor and heavy wings, the hybrid...journal article 2017

Machin Llanos, Jorge (author), Bouwmeester, J. (author)There are several benefits of using autonomous sensors in spacecraft. Avoidance of wired connections reduces cost, mass, and increases the flexibility and reliability of the system. The impact of wire reduction can be significant, especially for small satellites with many sensors, like temperature and sun sensors. Previous research has already...conference paper 2017

Aydin, B.E. (author), Rutten, M.M. (author), Abraham, E. (author), Oude Essink, GHP (author), Delsman, Joost (author)Surface water salinization in deltaic areas due to saline groundwater exfiltration is an important issue. Saline surface water will not be appropriate for drinking water production, agricultural and industrial use, and therefore, freshwater diverted from rivers is used for flushing the canals and ditches in coastal areas. The effects of climate...conference paper 2017

Dominicus, S. (author)The next generation of ground-based telescopes have a segmented primary mirror consisting of up to 800 segments which are mounted on a support truss. These segments are actively controlled to correct for external disturbances of which wind loading is the primary source. As mirror size and number of segments grows ever larger, dynamic coupling...master thesis 2016

Smit, B. (author)A new type of polymeric artificial muscle was recently discovered. This muscle is based on twisted and coiled polymer fiber and is actuated thermally. It has interesting properties, such as low costs and high work densities. Based on fabrication methods, two variations can be considered. The autocoiled variation has a larger load capacity and...master thesis 2016

Doekemeijer, B.M. (author)Wind turbines are often grouped together for financial reasons, but due to wake development this usually results in decreased turbine lifetimes and power capture, and thereby an increased levelized cost of energy (LCOE). Wind farm control aims to minimize this cost by operating turbines at their optimal control settings. Most state-of-the-art...master thesis 2016

Clarke, M.A.H. (author)The problem of testing the performance of an attitude control system presents new challenges and opportunities when conducted on a CubeSat scale. This is the result of drastic reduction in physical properties (size, mass, torques) as well as project resources (funds, manpower, time) when compared to traditional satellite programs. This thesis...master thesis 2016

Lara-Quintanilla, A. (author)The design of aerodynamic airfoils are optimized for certain conditions. For instance, the shape of the wings of fixed-wing aircrafts are designed and optimized for a certain flight condition (in terms of altitude, speed, aircraft weight, etc.). However, these flight conditions vary significantly during the flight. Currently, aircraft are...doctoral thesis 2016

Mol, N. (author)When tasks need to be performed in remote, potentially inaccessible and/or hostile environments for humans, it is often more convenient to send a robot. Such environments are often only partially known, and therefore not suitable for fully autonomous robots to operate in. In these situations teleoperation can be used, which combines the problem...master thesis 2016

Schuit, T.E. (author)In the oil and gas industry, safety and efficiency are taken into high regard when obtaining new natural resources. An increasing demand for automation arises to meet with the new safety and efficiency standards. During drilling operations, drilling fluid maintenance has an important role in guaranteeing safety on the rig. Controlling the...master thesis 2016
