Research on biped humanoid robots is currently one of the most exciting topics in the field of robotics and there are many ongoing projects. Because the walking of humanoid robot is complex dynamics inverse problem the pattern generation and dynamic simulation are extensive discussed. Many different models are proposed to simple the calculation. Many(More)
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)
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)
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)
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 WeierstrassMandelbrot function is introduced to characterize the surface spool’s microscopic surface. It can be certificated by the structure function and scale consistent with(More)
A method is presented for designing an individual teleoreactive agent, based upon discounted-reward evaluation of policy-restricted<lb>subgraphs of complete situation-graphs. The main feature of the method<lb>is that it exploits explicit and definite associations of the agent’s percep-<lb>tions with states. The combinatorial burden that would potentially(More)
Defects coming from processing and assembly inevitably bring geometric and concentricity error to the fitting gap between valve core and frame. To overcome this problem, grooving was proven to be the most simple and effective method to reduce the hydraulic clamping force, and widely used on cylinder valve cores. Theoretically unbalanced forces kept going(More)
