A Gait Generation Framework via Learning Optimal Control Considering Discontinuous State Transitions
Lower-limb exoskeletons have attracted considerable interest because they can provide impaired individuals with the ability to walk upright. Trajectory generation of walking gait is a crucial issue for lower-limb that has not yet been satisfactorily solved. The purpose this article study stable method considering subjective intention. Inspired by motion synergy between crutches and lower limbs,...
Background and purpose: High cost and complication of some instruments assessing functional capabilities in athletes with anterior cruciate ligament (ACL) deficiency have caused increasing attentions towards using inexpensive and user-friendly instruments as accelerometers and gait analyzing based on signal processing. Therefore, gait phases detection seems to be necessary while accelerometer i...
Objectives: This study aimed to compare elderly fallers and non fallers by balance test under dual tasks conditions. Methods & Materials: This study was a analyse-comparative study. Subjects were chosen from three parks of Tehran. Subjects were 20 older adults with no history of falls (aged 72.60±5 years) and 21 older adults with a history of 2 or more falls in the last one year (aged 74.50±...
Approximating the complexity of natural locomotor conditions provides insight into the diversity of mechanisms that enable animals to successfully navigate through their environment. When exposed to vortices shed from a cylinder, fishes hold station by adopting a mode of locomotion called the Kármán gait, whereby the body of the fish displays large, lateral oscillations and the tail-beat freque...
In this paper we present a novel gait analysis technique which can directly be used to synthesize gaits for a broad class of mechanical systems. We build upon prior work in locomotion mechanics, however we take a different approach to generate gaits that yield absolute motion of the mechanical system. We present a systematic analysis to control all parameters of a proposed type of gait which el...
In this paper, we propose a new method to generate C continuous gait motion for biped robots. The method is based on the enhanced inverted pendulum mode, which can easily handle angular momentum around the center of gravity. Using our method, it is possible to plan motion paths for biped robots without discontinuity in the acceleration even during switching from single support phase to double s...
