Duchenne muscular dystrophy (DMD) is a serious hereditary muscle disease that almost only occurs in boys and men and causes the muscles to become weaker over time. Given scientific research thus far, they are encouraged to obtain and maintain an active lifestyle. This may help delay the symptoms of the disease and help preserve their upper and...

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...

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...

Lower limb exoskeletons enable paraplegic patients to stand-up and walk again. However, the weight and overall functional performance of the exoskeleton prevents them from being widely used. To reduce the weight and increase<br/>the performance, pneumatic actuators can be used as an alternative to the commonly used electromechanical actuators....

In this paper, we present the design, control, and preliminary evaluation of the Symbitron exoskeleton, a lower limb modular exoskeleton developed for people with a spinal cord injury. The mechanical and electrical configuration and the controller can be personalized to accommodate differences in impairments among individuals with spinal cord...

Wearable robots assist individuals with sensorimotor impairment in daily life, or support industrial workers in physically demanding tasks. In such scenarios, low mass and compact design are crucial factors for device acceptance. Remote actuation systems (RAS) have emerged as a popular approach in wearable robots to reduce perceived weight...

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...

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...

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...

The main form of mobility for paraplegic patients is by wheelchair. However, not moving the legs comes with adverse health effects. Exoskeletons are one solution to get these patients walking again. One of the aims of exoskeleton research is the complete restoration of locomotion for paraplegic patients. The achieved gait must be stable, safe...

In this letter we demonstrate a pneumatic bending actuator for upper-limb assistive wearable robots which uses thin McKibben muscles in combination with a flexure strip. The actuator features both active soft actuation and passive gravity support, and in terms of force transmission bridges the gap between the classic rigid type actuators and...

For assistive exoskeletons, researchers have introduced soft exoskeletons (exosuits) because they tend to be lightweight, easily worn and mobile for daily use. However, most existing devices have not introduced closed-loop control methods that users can intuitively learn and use during activities of daily living. The goal of this pilot study is...

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...

Semi-autonomous robotic exoskeletons enable paraplegics to walk again. The exoskeleton envelops the paraplegic’s waist, legs and feet. When the user gives the command to start walking, the exoskeleton’s robotic legs start a cyclic walking motion. The user, aided by crutches, follows this fixed cyclic motion, shifting their weight to the stance...

Recognising the user’s locomotive intentions is crucial for the correct functionality of exoskeletons and active orthoses. For gait applications, extrapolating control inputs from the arm swing may be worthwhile, since arm oscillations naturally occur during human locomotion. A similar method would be unaffected by severe impairments of the...

This paper introduces a novel control framework for an arm exoskeleton that takes into account force of the human arm. In contrast to the conventional exoskeleton controllers where the assistance is provided without considering the human arm biomechanical force manipulability properties, we propose a control approach based on the arm muscular...

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...

The company Intespring is currently developing a load-carrying exoskeleton for military personnel in order to reduce the impact of the ever increasing backpack load on their body: the Exobuddy. The current mechanical design gives rise to problems, i.e. the exoskeleton occupies a large space and applies torques on the legs of the user during...

Complex motions are generally accepted as movements which consists of at least 2 Degrees of Freedom (DoFs) actuated in a coordinated manner, which takes more than one practice session to be mastered, and that are ecologically valid (see Wulf et al. 2002 for a clear statement). <br/><br/>The techniques to teach and re-teach (also, (re-)learn) a...

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...
