This paper presents results of research devoted to tracking human arm trajectories in sagittal plane by means of motion capture. One camera tracking system was developed. Co-ordinates of upper limb joints (distincted by light reflecting markers) were obtained via tracking software. Markers were illuminated coaxially to the optical axis of the lens to obtain maximum of reflectivity. Positions, linear...
An analysis of the gait stability of the man moving along an even surface with a constant velocity is presented. The stability criteria applied to biped robots, namely: the ZMP (Zero Moment Point) and the GCOM (Ground projection of the Center Of Mass) have been employed in the investigations. The analysis has been carried out on the basis of the measurement data obtained from the human gait recorded...
The main objective of this study is to design three-dimensional geometrical and mechanical finite element model of the intervertebral disc between L2-L3 vertebras in the lumbar and C5-C6 cervical spinal segment. The model was directed toward understanding the work and the role of the intervertebral disc that performs in the human spinal segment body. The three-dimensional finite element motion segment...
