The goal of the project SFB588 supported by the Deutsche Forschungs-gemeinschaft (DFG) is to generate concepts, methods and a concrete prototype of a humanoid robot. The intended application area is, for instance, a generic kitchen, where the robot is planed to perform actions autonomously at the user's request. In this paper, a model of stable analysis of(More)
The computational fluid dynamics (CFD) has been showing a good prospect for the past decade. CFD is widely used for it can help people understand cavitation from the Micro-level and it can provide the scientific means to describe the mechanism of fluid vibration. Cavitation flow can result in annoying, unbearable noise and high vibration, and reduce the(More)
A model of walking stability analysis of a humanoid robot is given, in which the different environments are considered. By applying the concept of fictitious zero-moment point (FZMP), a method to maintain the walking stability of humanoid robot under external disturbance is presented. The support polygon and the rotation edge in the case of losing balance(More)
Using Weierstrass-Mandelbrot (W-M) function, characterization is done on the microscopic surface contours, structure function and scale consistent with a power-law relationship. The Weierstrass-Mandelbrot function is introduced to characterize the surface spool's microscopic surface. It can be certificated by the structure function and scale consistent with(More)
This paper presents the computational results of studies on the flow characteristics of V-U and U-U notch. To simulate the flow features, three-dimensional models are developed as commercially available fluid flow models. The computational fluid dynamics (CFD) is then used to analyze the flow features of throttle notches of valves. Numerically simulated the(More)
