De Lange, L.F.M. (author)
The life expectancy of humans increases due to better medical care, food quality and personal hygiene. The demand for domestic robots performing (simple) household chores will increase as consequence to this trend. An important task of these robots is recognizing objects within an environment. Object models are constructed using multiple views...

With the provision of essential surgical care millions of lives can be saved and this realization has reached the international agenda. There are however many obstacles that make it hard to provide safe, qualitative, affordable and accessible surgical care to the more than 4.8 billion people for whom this is currently out of reach. One of the...

Reinforcement learning is a powerful tool to derive controllers for systems where no models are available. Particularly policy search algorithms are suitable for complex systems, to keep learning time manageable and account for continuous state and action spaces. However, these algorithms demand more insight into the system to choose a suitable...

Collagen gels hold great promise in the field of tissue engineering as collagen is highly biocompatible, biodegradable, abundant in nature and it provides an optimum environment for tissue regeneration and restoration of normal tissue function. However, collagen hydrogels have poor mechanical strength due to low collagen proportion and thus are...

Shimmy, or wobble, denotes the unstable self-excited oscillatory motion of the wheel around the steering axis and can be found in vehicles with castor wheels. For bicycles this oscillatory motion is normally in the range between 5 - 13 Hz. Shimmy could be frightening, dangerous and even fatal if not controlled in time. The introduction of...

Haptic technology is more and more widely used to improve human interaction with devices, for example in touch screens of smartphones that vibrate when touched. Another application is haptic-tele-manipulation where a human controls a slave manipulator (e.g. a surgical-robot) by using a master device (e.g. a joystick). In haptic-tele-manipulation...

Currently haptic technology is being widely implemented in applications such as tele-operation. One of the main concerns are the communication delays due to the visual or haptic feedback signals traveling long distances. Also, different subsystems handling visual and haptic feedback cause modality-specific delays causing asynchrony between...

Objectives System identification techniques have the potential to assess the contribution of the underlying systems involved in standing balance by applying well-known disturbances. We investigated the reliability of standing balance parameters obtained with multivariate closed loop system identification techniques. Methods In twelve healthy...

Body-powered hand prostheses are characterized by low weight and low cost compared to externally powered prostheses. They also provide force and position feedback, allowing for accurate and fast position and force control of the prosthesis. Body-powered hand prostheses are often rejected on the basis of low efficiency. The high forces needed to...

Recent research has shown the potential of rationally designed geometrical features for controlling the functionality of advanced materials. Of particular recent interest has been the use of geometry for controlling the buckling behaviour of soft materials under compression. However, the effects of geometry may be mixed with those of the...

Laparoscopic suturing can be very time consuming and frustrating for inexperienced surgeons. It is one of the hardest actions to perform in a laparoscopic fashion, but it remains the golden standard. There are alternative fixation methods such as automatic needle passers, knot-tying devices, staplers, tackers and adhesives but they all have...

Chronic total occlusions (CTOs) represent the “last frontier” of percutaneous interventions. The main technical challenges lies in crossing the guidewire into the distal true lumen, which is primarily due to three problems: device buckling during initial puncture, inadequate visualization, and the inability to actively navigate through the CTO....

Falling is one of the major causes of unintentional death or injury worldwide. People older than 65 years and people suffering from neurological disease have a higher chance of falling, which indicates the involvement of higher brain structures such as the cortex. For this reason, cortical activity underlying balance control has been subject of...

Chondrocyte is the only cell type which constitutes the articular cartilage, is solely responsible for the turnover of extracellular matrix composed of proteoglycans, type II collagen and water. Chondrocytes experience a unique ionic/osmotic environment, which is attributable to the polyanionic proteoglycan, which carry a high fixed negative...

The purpose of this study is to develop and validate a Human-like steering model which can capture steering behaviour, including intra-driver variability, in both routine and emergency scenarios. The model is based on the assumption that steering behaviour, in both scenarios, is governed by the same principles as performing point-to-point...

Current neuromechanical muscle models are unable to accurately estimate both passive and active muscle components. In this study it is investigated to increase the neuromechanical parameter estimations by using an input-rich measurement protocol and by expanding the ankle muscle model with tendon dynamics. New measurement protocols are developed...

Pushoff in speed skating requires an extensive motion strategy. During speed skating the skater continuously changes the lean and steering angle of the skate and therewith the direction of push-off, The forces in an inertial coordinate system can give insight into what amount of the push-off force is directed into the forward motion. In this...

Quantitative assessment of an athlete׳s individual wheelchair mobility performance is one prerequisite needed to evaluate game performance, improve wheelchair settings and optimize training routines. Inertial Measurement Unit (IMU) based methods can be used to perform such quantitative assessment, providing a large number of kinematic data. The...

In baseball, pitchers are the players that are most prone to injury. Most injuries occur at the elbow and shoulder of the throwing upper limb. It is widely accepted that understanding the loading in the joints during pitching is a key factor to prevent injuries. To deepen the understanding of the joint actions this study proposes to split the...

In the current project, we aim to provide speed skaters with real-time feedback on how to improve their skating performance within an individual stroke. The elite skaters and their coaches wish for a system that determines the mechanical power per stroke. The push-off force of the skater is a crucial variable in this power determination. In...
