Verdoes, Floris (author)This design project marks the collaborative efforts of Translas, a prominent welding company based in the Netherlands, and Skelex, a scale-up enterprise specializing in exoskeleton design. Translas developed the 8XE fume extractor torch. However, a common complaint of the new torch is its decreased usability and potential ergonomic risk. To...master thesis 2023

Wei, Tom (author)DMD (Duchenne muscular dystrophy) is a genetic disorder characterized by progressive muscle weakness, leading to the eventual loss of muscle function. After losing lower extremity function, DMD patients lose the ability to use their arms. To assist individuals with DMD, an upper extremity exoskeleton is being developed to provide support. <br/>...master thesis 2023

Schuurbiers, Stefan (author)Of all reported cases, muscular pain in the arms is the second main cause of work-related musculoskeletal disorders (WMSDs) in European workers. The most popular prevention method for shoulder-related WMSDs are passive shoulder exoskeletons, as of their light weight and ease of use. Yet, due to their static force-angle characteristic, passive...master thesis 2022

Kluwen, Daan (author)Rehabilitation robotics is a rapidly growing field in the engineering industry. Due to the high repeatability of motion, high therapy costs, and lack of proper quantitative assessment of patient status and progress, rehabilitation centers could benefit from the introduction of robotics. One such device already commercially available is the...master thesis 2022

Mak, Robin (author)People in healthcare, warehousing, and the agriculture sector all have one thing in common. They require labour which can be demanding on the human body, this could lead to problems in the long term. A way to alleviate these problems is to use a passive exoskeleton. While passive exoskeletons can have a variety of different use cases and types...master thesis 2021

Gerlach, Robyn (author)This report proposes a concept for an I-profile curved beam compliant transmission system. The application of this system can be as a hip connection within a passive exoskeleton in which it transfers the walking motion from one leg to another. To obtain the desired behavior the torsion stiffness is reduced and the amount of work needed to move...master thesis 2021

Bouwers, Douwe (author)In 2011, the world watched in amazement how IBM’s AI named Watson won at Jeopardy!. Right afterwards, IBM decided to use this power to revolutionize the healthcare system. AI doctors would change everyone’s lives. Sadly, Watson did not revolutionize healthcare. It did not prove to be as useful in reality as was anticipated. How could this happen...master thesis 2020

Dingemanse, Donald (author)Introduction<br/>This project is about designing a tailor-made hand orthosis for hand support of patients with Amyotrophic Lateral Sclerosis (ALS) -Limb onset to increase independence during desired activities. According to the National Institute of Neurological Disorders and Stroke (2014), ALS, is a progressive neurodegenerative disease which...master thesis 2020

Vermeer, Lindsey (author)Boys with Duchenne Muscular Dystrophy have a different life from most children. As they grow up, their muscles lose strength progressively. Around the age of 10, they lose their ability to walk, in their teens they slowly lose their arm function, in their twenties they often need respiratory support and their life expectancy is usually between...master thesis 2020

Wagemaker, Bas (author)In Chapter 1, the focus is on the classification of force generators, which is the family of mechanisms to which balancers belong to. The goal of this chapter is to introduce a bottom-up classification method to identify the complete solutions space of transmissions in force generators based on their transfer function. Using this method, spring...master thesis 2019

Elzinga, Maurits (author)Neurologically impaired patients can regain motor function by engaging in rehabilita- tion. Currently there is no conclusive evidence that robotic rehabilitation has better clinical results than conventional rehabilitation but robotic rehabil- itation has the potential to increase efficiency and patient motivation, justifying improvement of reha...master thesis 2018

van Dijk, Nick (author)The human machine-interface is more important than ever in the field of exoskeletons. Current design approaches lack a way of systematically designing the ergonomics of exoskeletons. Methods with a more pro active approach to ergonomics have to be developed. This thesis extends existing methods by which self aligning mechanisms are created with...master thesis 2018

Brons, Rick (author)The restoration of the walking function of paraplegic patients requires long and extensive training. Physicians themselves are not able to provide this training due to the physical labour required. Robots and soft exoskeletons are in development to assist the physicians in this task, however, they are either bulky and restrictive or lack a...master thesis 2018

Siebinga, Olger (author)Currently, lower-body exoskeletons for<br/>paraplegics are investigated as an alternative to wheelchairs<br/>and as an exercise method with medical benefits. Literature<br/>provides little examples for users to influence the<br/>length or frequency of steps taken by the exoskeleton,<br/>complicating stability and practical usability. This study...master thesis 2018

de Boer, Friso (author)Ever since human ancestors picked up rocks and used them as tools, technology has enhanced human capabilities. Over the last decades more and more research has been done in trying to enhance strength and endurance by means of an exoskeleton. Reducing the metabolic cost of human walking using lower extremity exoskeletons is one of the challenges...master thesis 2017

de Looij, Ivo (author)The SkelEx exoskeleton is a non-linear spring-based passive upper body exoskeleton that has the goal to compensate the weight of the wearer's arms. Bending of three stacked non-linear springs transfers force from the hips of the wearer to the back of the upper arm. The amount of bending of the springs is a function of the geometry of the...master thesis 2017

Van Mastrigt, G. (author)After a visit at a revalidation center in The Hague a design goal was established: Providing motor neuron disease (MND) patients with upper arm functionality to improve their quality of life. MND patients gradually lose function of their muscles, even their respiratory muscles. It has a severe impact on their own life, but also the lives of...master thesis 2016

Huberty, L. (author)Recent studies suggest that a reduction of the plantar-flexion muscle EMG can improve the efficiency of human locomotion. In this study, an attempt is made to reduce the maximal EMG of the gastrocnemius medialis and soleus by providing a feed-forward torque support around the ankle. The strategy only requires the ankle kinematics to define the...master thesis 2012

Maathuis, G.A. (author)This thesis presents research done on XPED, a passive walk assisting exoskeleton. It uses exotendons to assist the user, which are elastic elements running over multiple joints which are able to store and redistribute energy over these joints. A computer model predicts that joint powers of the user would decrease when walking with XPED, compared...master thesis 2012
