The mechanisms that move plants can serve as biological role models for engineers, designers and architects. This practice is slowly being implemented in various engineering fields, with architects often being pioneers. Various methodologies have been written about the subject, but often only from an architectural point of view.<br/>The...

Abstract Pilot study Introduction: Falls are a primary cause of accidental deaths, serious injuries, dependency and society costs. The response to perturbations could identify how well persons are able to reject perturbations. The aim of the study was to compare four different medio-lateral swing perturbations in order to select the most...

In the elderly population, falls are one of the major causes of injuries. Fall detection algorithms for wearable devices in the literature were found to focus on differentiating Activities of Daily Living (ADL) from falls, rather than on early fall detection and prevention before impact. This thesis work was aimed at providing accurate estimates...

A new type of polymeric artificial muscle was recently discovered. This muscle is based on twisted and coiled polymer fiber and is actuated thermally. It has interesting properties, such as low costs and high work densities. Based on fabrication methods, two variations can be considered. The autocoiled variation has a larger load capacity and...

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...

This thesis presents the first steps of a design study on the robust hopping and balancing robot Skippy. The purpose of the overall design study is to challenge a new design approach for robots with high physical performance. This approach comprises an iterative study of machine (physical system) and behaviour (action strategy) co-design. Skippy...

The human ankle-foot complex is an intricate piece of machinery. It enables a stable stance, ambulation, and an effective transfer of force through the lower limb. Although state-of-the-art humanoid robots feature highly advanced kinematics, the robotic foot has seen little research resulting in humanoids equipped with simple feet. Simple feet...

A minimalistic robotic device for aiding persons with degraded balancing ability was recently proposed, employing a number of single-gimbal control moment gyroscopes (CMGs) mounted to a backpack-like orthopedic corset. Once a fall is detected, the device must track a predefined moment profile to bring the subject upright or else slow the fall...

Knowledge of the state of balance of the moving human is essential for the design of fall detection algorithms and wearable robotic controllers for balance assistance. Still, there is no known general method to make an online estimation of the state of balance of the walking human, with the limited and local sensor measurements that are usually...

To allow for efficient and robust gait pattern, humans instantaneously modulate their joint impedance. Lower-limb amputees and patients suffering from neurological diseases partly lack that ability. Therefore, prosthetic and rehabilitative devices have been designed to re- store and repair nominal locomotion. For bio-inspired control of these...

Falls and fall-related injuries are among the most serious and common medical problems experienced by the elderly. Support could be given to prevent severe injuries from those falls. Therefore the design of a robotic assistive device is currently investigated in the MARS3-project. Such a device requires knowledge of the human posture to...

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...

The number of amputees is expected to grow drastically in the coming years as a result of dysvascular disease, trauma and cancer. Therefore the need for foot prostheses will increase and currently a new generation of prostheses with improved physiological characteristics is under development. However, testing of new prostheses is costly and time...

Currently a lot of research is performed in the field of walking robots and especially on bipedal humanoid robots. Successful walking robots have been made but there are still problems that have to be overcome to make them as versatile, robust and energy efficient as human beings. One of these problems is the control of balance after taking a...
