Multicriteria Optimization of Lower Limb Exoskeleton Mechanism

Applied Sciences, 2023
Typical leg exoskeletons employ open-loop kinematic chains with motors placed directly on movable joints; while this design offers flexibility, it leads to increased costs and heightened control complexity due to the high number of degrees of freedom. The use of heavy servo-motors to handle torque in active joints results in complex and bulky designs ...

An Anthropometrically Parameterized Assistive Lower Limb Exoskeleton

Journal of Biomechanical Engineering, 2021
Abstract This paper presents an innovative design methodology for development of lower limb exoskeletons with the fabrication and experimental evaluation of prototype hardware. The proposed design approach is specifically conceived to be suitable for the pediatric population and uses additive manufacturing and a model parameterized in ...

Design and Evaluation of a Soft Assistive Lower Limb Exoskeleton [PDF]

Robotica, 2019
SummaryWearable devices are fast evolving to address mobility and autonomy needs of elderly people who would benefit from physical assistance. Recent developments in soft robotics provide important opportunities to develop soft exoskeletons (also called exosuits) to enable both physical assistance and improved usability and acceptance for users.

Optimisation of Reference Gait Trajectory of a Lower Limb Exoskeleton

International Journal of Social Robotics, 2015
Lower limb exoskeletons have gained considerable interest in recent years as a research topic for creating aids for people with walking disabilities and strength augmenters for pilot walkers. A crucial practical problem, however, is generating the reference trajectory of the joints.

Lower Limb Exoskeleton Sensors: State-of-the-Art. [PDF]

Sensors (Basel), 2022
Due to the ever-increasing proportion of older people in the total population and the growing awareness of the importance of protecting workers against physical overload during long-time hard work, the idea of supporting exoskeletons progressed from high-tech fiction to almost commercialized products within the last six decades. Sensors, as part of the

Human assistive lower limb exoskeleton [PDF]

Exoskeletons have proven to be helpful in assisting humans in major fields such as rehabilitation, military, industries and more. However, even though these exoskeletons provide useful features,most of them fail to reach humans in need due to their high cost.

Biomechanical models in the lower-limb exoskeletons development: a review [PDF]

Journal of NeuroEngineering and Rehabilitation, 2023
Abstract Lower limb exoskeletons serve multiple purposes, like supporting and augmenting movement. Biomechanical models are practical tools to understand human movement, and motor control. This paper provides an overview of these models and a comprehensive review of the current applications of them in assistive device development.

DESIGN OF A LOWER-LIMB EXOSKELETON [PDF]

DYNA, 2019
In recent years, many mechanisms have been developed to help people with reduced mobility, especially for people who have injuries that do not allow the mobility of the lower body of the human body. In the present work, the properties and mechanical movements of a human being, angles of movement, extension and flexion of the hip, knee, etc.
