Most ground robots deployed in disaster areas have been of limited use mainly because of their reduced mobility in degraded environments. Unmanned Aerial Vehicles (UAVs) have considerable mobility benefits over ground robots, however they are currently only used for providing aerial views and often lack any manipulation capabilities, despite...

Conventionally programmed systems (e.g. robots) are not able to adapt to unforeseen changes in their task or environment. Reinforcement learning (RL), a machine learning approach, could grant this flexibility. Many fields of work could greatly benefit from this, be it in terms of cost, time or some other parameter. With RL, a learning agent...

In the field of neurorehabilitation, robots are being used to provide assisting forces for therapeutic purposes, and with system identification & parameter estimation (SIPE) methods they are used to quantify neuromechanical parameters for diagnostic purposes. To better understand the beneficial effect of robotic assistance on the neuromechanical...

A flexible bone drill provides advantages over conventional rigid instruments, because it allows surgical access via a minimally invasive approach. A new concept is to achieve this using hydropower. Hydropower could provide the advantage of energy transfer via a compliant hose through which pressurized water is flowing. The goal is to design a...

A common method to obtain workspace extension of the slave's workspace is through rate control because it has an unlimited workspace of the slave. However, when contact interaction with the remote environment is needed, position control is often proposed due to the force feedback. To benefit from the strengths of both of these control types,...

Background: Chronic Total Occlusions (CTOs) are the most challenging lesions of Percutaneous Coronary Intervention (PCI). The most common failure mode is the inability to cross the lesion with a guidewire. Crossing is complicated by the lack of guidewire stiffness and the high penetration force of the fibrous proximal cap of the CTO, often...

Recent improvements in mobile technology have allowed computationally intensive augmented reality systems to become increasingly ubiquitous. As will be shown in this thesis an increasing number of companies have started developing markerless AR systems that can be used professionally. Robust pose estimation is essential for such systems to...

The main reason for accidents involving trucks or truck combinations is the lack of situation awareness. Drivers of particularly articulated truck combinations need a high level of awareness about the state of the vehicle combination and its surroundings. The current steering interface sets limits on the signals that the driver can perceive and...

Physicians use small variations in the needle insertion force to identify tissue properties and detect membrane punctures during needle insertion. Navigation of a needle towards the target tissue, for example to take a biopsy, is often based on detecting these variations in force. Literature shows that presenting physicians force feedback based...

Locking mechanisms are used in a wide range of applications including energy saving mechanisms in the field of robotics. In this thesis a new class of locking mechanisms is investigated: a combination between a singular- and a friction locking mechanism (singular-friction locker) which is statically balanced with one additional spring. This...

CO2 powered actuators are a viable alternative in prostheses and robotics. The gas supply is generally limited in such applications, and calls for an optimal system pressure to minimize gas-consumption. Previous work which discusses the optimal pressure was not verifiable, or strictly theoretical. The theoretical work was unintuitive, but did...

Due to population ageing, the cost of health care will raise in the coming years. One way to help humans, and especially elderly people, is the introduction of domestic robots that can assist people in daily life such that they are less dependent on home care. Joint visual attention models can be used for natural robot-human interaction. Joint...

Driving a car is common but complex everyday task. Nowadays the mobile phone, infotainment and navigation systems are used while driving. These distract the driver from their driving task. What is the implication on driving safety? How is the car following behaviour influenced by distraction? Can this be described by a car following model? The...

Adding emotion to motion, or creating emotionally meaningful movement is one of the next steps in robotics. Non-verbal communication between humans and robots has the potential to raise the current interaction level to a next stage. This study is a contribution to the field of emotion expression in robotics. Several parameters are known for...

Abstract—As current rigid needles follow straight line trajectories, limiting the path planning possibilities in minimally invasive surgical approaches, research into steerable needle instruments becomes necessary. This article outlines the development of a four-part needle prototype inspired by the ovipositor of parasitic wasps and designed to...

Summary: The need for vision guided mobile robotics is becoming more apparent, however it is proven to be troublesome to stabilize its vision. For two legged robots, it is, during motion, even more difficult than for wheeled robots to be able to perceive the world around it. Finding a stabilization method which is able to reduce the motion blur...

Sensors are the eyes and ears of an automated vehicle. An automated vehicle has to detect other road users and should be able to interact with them in a safe way, hence it is important to understand what the vehicle's sensors should be capable of. We have investigated the different driving scenarios one can encounter in highway and rural...

The aim of this study was to determine if and how specific characteristics of visual information influence the motor control strategy adopted during a visuomotor tracking task. To this end, twenty healthy subjects and two stroke patients were measured. Changes in wrist joint admittance (i.e., wrist rotations due to external forces) due to...

In rough and highly unstructured terrain, legged locomotion exhibits remarkable capabilities when compared to wheeled systems. The mobility of the wheeled systems are restricted to continuous path with small obstacle, legged locomotion requires only few proper footholds to compromise those obstacle, this makes legged locomotion ideal for...

Three degree-of-freedom (3-DOF) tool-based haptic interfaces are widely used in virtual environment to train operators, and for virtual prototyping and design. In some special cases with higher requirement on haptic fidelity, the tool needs to be modeled as an object with real volume rather than a single point. However, such object -to-object...
