Reinforcement learning can use similarities between tasks to enable faster learning. Parameterized Skills is a state of the art reinforcement learning algorithm that does this. The algorithm consists of two steps. First, reinforcement learning is used to learn the parameters of a control policy that optimize the reward for training tasks. Second...

The goal of the Human Power Team from the TU Delft and the Free University of Amsterdam is to break the world speed record in unpaced cycling (Sam Whittingham, 133.28 km/h). The design of such a faired recumbent bicycle is a challenge. The Delft design, called VeloX (Human Power Team (2013)), is a fully-faired monocoque front-driven recumbent...

Musculoskeletal models can be used to distinguish too short or too slow muscles in Cerebral Palsy patients. Therefor muscle-tendon geometry needs to be modeled accurately in order to predict the need and effectiveness of muscle-tendon lengthening. This geometry is strongly related to the location and orientation of the joint centres. In clinic...

The technique of speed skating is unique in comparison to other sports that require human propulsion. Skaters generate a forward velocity by pushing off sideways. The ideal push-off technique is a trade-off: a more sideward directed push-off facilitates power production, but a more forward directed push-off increases the transfers rate of push...

Electronic stability control (ESC) has been shown to reduce the accident rate in a number of situations. Therefore, it is important to keep improving ESC and other control systems. One way to do this is by improving the available information on the state of the vehicle and its environment. The tire-road friction coefficient µ is particularly...

Cortical involvement during upright walking is not well-studied in humans. We analyzed non-invasive electroencephalographic (EEG) recordings from able-bodied volunteers who participated in a robot-assisted gait-training experiment. To enable functional neuroimaging during walking, we applied source modeling to high-density (120 channels) EEG...

Easy access to the current status of a surgery in the operating room (OR) can be beneficial to hospitals since it can improve the working efficiency and reduce the operational costs. Using indoor positioning systems (IPS) to obtain the position information of medical staffs in the OR could be an indirect method to enhance the awareness of the...

Humanoid robots could perform a large variety of tasks, ranging from helping the elderly and entertainment to carrying out repairs in hazardous environments such as nuclear power plants. Therefore, they are an important topic of research. However, controlling the balance of two-legged robots still proves to be a challenge, especially during more...

Neuroprosthetic technology and robotic exoskeletons are being developed to facilitate stepping, reduce muscle efforts, and promote motor recovery. Nevertheless, the guidance forces of an exoskeleton may influence the sensory inputs, sensorimotor interactions and resulting muscle activity patterns during stepping. The aim of this study was to...

In small to medium enterprises (SME), industrial robot arms are not used very much despite the fact that they offer a large potential to increase the competitiveness. The problem is that to be effective in the SME sector, robot systems should be more flexible. To be economically effective a robot arm should be used with multiple different tasks...

Background – With the growing costs in healthcare and the growing need for care, prediction models offer great opportunities for improving efficiency and patient outcome. With these models, one can manage the different outcomes as efficient as possible and next to that, understand which variables influence the patient’s pathway. The Erasmus...

Highly advanced robotic hand prostheses are praised for their impressive grasping and pinching capabilities. Nevertheless, a high demand remains for grasping mechanisms that are cheaper to produce, easier to assemble and lower in overall maintenance. In this paper, the idea of creating a 3D printable underactuated grasper was realized to fulfill...

Windsurfers currently do not wear neoprene gloves when sailing in cold temperatures, as discomfort rapidly develops in the forearms when doing so. Lack of good protection against low temperatures means the hands get painfully cold and numb, limiting sailing time and pleasure. ElectroMyoGraphy (EMG) measurements were done on four forearm muscles...

Sit-snowboards allow a person with the inability to actively use his/her legs to snowboard while sitting. However, existing prototypes do not allow using a chairlift. The goal of this study was to modify a prototype sit-snowboard, MINI, to add chairlift accessibility. MINI has a seat construction and two handlebars which allow the user to steer...

Bone tissue engineering has been increasingly studied as an alternative approach to bone defect reconstruction. In this approach, new bone cells are stimulated to grow and heal the defect with the aid of a scaffold that serves as a medium for bone cell formation and growth. Scaffolds made of metallic materials have preferably been chosen for...

Diffuse reflectance spectroscopy (DRS) allows spectral tissue sensing through optical fibers at the tip of a needle, endoscope, or other medical device. A so-called photonic tool could be applicable in a variety of application areas to aid in diagnostic decisions or to support image-guided procedures. The use of light in combination with medical...

People in both developing and developed worlds are increasingly facing musculoskeletal problems that require long-term clinical performance of orthopaedic implants including bone substitutes. Porous biomaterials could play an important role in improving the longevity and overall performance of orthopaedic implants and that is why they have been...

Background: An ablation catheter with integrated high-frequency single element ultrasound transducers has been developed by Philips Research, which makes it possible to assess tissue-depth and lesion formation in real-time. The interpretation of the acquired ultrasound M-mode images is difficult due to a combination of cardiac motion and motion...

Implant failure related to polyethylene wear remains an important issue in total knee arthroplasty. Polyethylene wear is usually assessed in vivo by measuring the remaining insert thickness on X-ray images of the knee. To reflect the amount of wear debris more accurately, a 3-dimensional overlap measurement has been suggested, which is based on...
