There are numerous causes that can affect the functioning of the human locomotor system, leading to the appearance of joint disorders in the lower limb and generating atypical gait patterns. The importance of research and development in assistance technologies to compensate pathological gait have been recognised since the beginning of the twentieth century and numerous challenges still lie ahea...

Exoskeleton is a type of wearable robots that can augment the performance of an able-bodied user. There are many studies that use hydraulic actuator to actuate the lower limb exoskeleton which possesses several drawbacks like dirty, noisy and high power consumption. Therefore, electrical actuators that are clean, silent and less power consuming are used in designing the lower limb exoskeleton i...

This paper will provide the kinematic and dynamic analysis of a lower limb exoskeleton. The forward and inverse kinematics of proposed exoskeleton is performed using Denevit and Hartenberg method. The torques required for the actuators will be calculated using Lagrangian formulation technique. This research can be used to design the control of the proposed exoskeleton. Keywords—Dynamic Analysis...

BACKGROUND Despite a large increase in robotic exoskeleton research, there are few studies that have examined human performance with different control strategies on the same exoskeleton device. Direct comparison studies are needed to determine how users respond to different types of control. The purpose of this study was to compare user performance using a robotic hip exoskeleton with two diffe...

Abstract The research on exoskeleton robots has been widely carried out for many years around the world, especially development of new-style lower limb exoskeletons rehabilitation and assistance is one key directions. focus control system discussed. Based public literature in recent years, it summarized from three aspects, i.e., movement mode switching, human gait recognition human-exoskeleton ...

We propose a new approach called as a peak time approach for faster detection of step initiation for the lower limb exoskeleton. As faster detection of step initiation is an important criterion in evaluating the lower limb exoskeleton, many studies have investigated approaches to detect step initiation faster, including using electromyography, the center of pressure, the heel-off time and the t...

Many of the current implementations of exoskeletons for the lower extremities are conceived to either augment the user's load-carrying capabilities or reduce muscle activation during walking. Comparatively little research has been conducted on enabling an exoskeleton to increase the agility of lower-limb movements. One obstacle in this regard is the inertia of the exoskeleton's mechanism, which...
