Abstract   The simple passive dynamic walker can walk down a shallow downhill slope with no external control or energy input. Nevertheless, the period-one gait stability is only possible over a very narrow range of slopes. Since the passive gaits are extremely sensitive to slope angles, it is important to use a control strategy in order to achieve a wide range of stable walking. The computed to...

Abstract The purpose is to define the range of feasible speeds for two walking motions a particular planar biped robot, which differ in definition their finite-time double support phases. For each speed, these are numerically obtained by using parametric optimization algorithm, regarding sthenic criterion. Results allow us allowable walking. One result that first gait less consuming energy mode...

The characteristics of vertical ground reaction force (VGRF) gait patterns in children with autism spectrum disorders (ASD) are poorly understood. The purpose of this study was to identify VGRF gait features that discriminate between children with ASD and the peer control group. The VGRF data were obtained from 30 children with ASD and 30 normal healthy children aged 4 to 12 years. A three-dime...
