New flexible teaching methods for robotics are needed to automate repetitive tasks that are currently still done by humans. For limited batch sizes, it is too expensive to teach a robot a new task (Smith & Anderson, 2014). Ideally, such flexible robots can be taught a new task by a non-expert. A non-expert is a person who knows the task the...

Introduction. Ultrasound is known for cheap, fast and non-invasive diagnosis of numerous injuries. Sport-related injuries in the ankle joint and rehabilitation after surgical intervention are badly diagnosable using traditional ultrasound. Bones surrounding the surface of the articular cartilage blocks the ultrasound pulse and hides the talar...

The Delft University of Technology intends to aid in the development of autonomous vehicles by building their own experiment platform in the DAVI project. To be able to make valid decisions, an autonomous vehicle needs to know its surroundings. Many sensors are used to detect any objects within range, but the sensor information has to be...

As a ways of avoiding issues with conventional socket suspended prostheses, a new type of fixation for limb amputees has been developed and is gradually gaining popularity around the world. Rather than tightly clamping the prosthesis around the skin of the residual limb, a titanium fixture is implanted into the bone and a transcutaneous pin is...

Muscle spindle is an organ of proprioception that plays an important role in neuro-muscular control of the human joints. It is composed of intrafusal fibers, the mechanical properties of which determine the afferent response of the spindle. Intrafusal fibers are not homogenous: they are composed of many sarcomeres, have localized fusimotor...

Automated driving is becoming increasingly popular and is often proposed as a solution to commonly known human errors in driving. However, fully autonomous driving has not yet reached the point where it can be implemented in real world driving. Current automated driving systems are often designed in such a way that the role of the human operator...

The digital environment has an ever increasing amount smart programs. Programs that also get smarter every day. They help us filtering spam e-mail and they adjust to show us personalized advertisements. These smart programs observe people and serve (other) people. A robot can be seen as a program with a body. Make the program smart enough and it...

In many percutaneous interventions, such as biopsies and brachytherapy, accuracy in reaching a specific target inside the human body is necessary for the success of the procedure. Maneuvering to the target site is challenging, particularly if sensitive structures such as blood vessels have to be avoided. For maneuvering along a curved trajectory,...

There are still important knowledge gaps regarding stability and safety of bicycle riding. Every year around 60,000 people need hospital treatment for single sided accidents in the Netherlands alone. Supporting the need for understanding lateral bicycle dynamics. One of the prominent disturbances on lateral bicycle and rider behaviour is...

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...

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...

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...

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...

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...
