In the trot, the body’s center of mass behaves differently. Rather than being raised in the first half of the stance phase, it is lowered and the body moves as a wave, often with minimal oscillation in those breeds of dogs that are used to trotting for long periods of time [6]. Here potential energy is converted into elastic energy and stored upon impact with the ground by passive stretching of...

Abstract The upper limb exoskeleton robot has been a key research direction at home and abroad in recent years. Still, the existing poor coupling with human body, power assistance effect could be better. In this paper, strength of each muscle group when body is carrying objects measured as reflected by surface EMG signal kinematics analyzed to guide design passive limb. First, spring tension co...

Passive vibration isolator with lower natural frequency has always been a challenge due to structural integrity issues. This study presents the use of RSM statistical tool analyze and optimize mechan-ical responses BCC lattice structure for in passive application. The optimization was done obtain low stiffness but high yield stress optimum load-bearing capability unit cell size strut diameter d...

We study nonlinear transmission of an asymmetric multilayer structure created by alternating slabs of two materials with positive and negative refractive indices. We demonstrate that such a structure exhibits passive spatially nonreciprocal transmission of electromagnetic waves, the analog of the electronic diode. We study the properties of this left-handed diode and confirm its highly nonrecip...
