Abstract
Das Verstehen der Funktionsweise biologischer Systeme und ihre Modellierung ist fur die Erarbeitung neuer Wirkprinzipien nach biologischem Vorbild eine wesentliche Grundlage. Dafur leistet die vorliegende Arbeit einen Beitrag. Die Resultate der Arbeit zeigen, das Modellierung und Simulation des Bewegungsmechanismus des Spinnenbeines auf der Basis eines Starrkorpermodells unter der Betrachtung des hydraulischen Antriebs moglich ist. Die Ubertragung der Konstruktions- und Wirkungsprinzipien aus dem biologischen Bereich auf die technischen Systeme (auch Mikrosysteme) ist anschaulich am Beispiel eines Greifers demonstriert worden. Dabei soll jedoch nur die grundsatzliche Moglichkeit der Realisierung eines Greifers nach dem Vorbild des Spinnenbeines geschildert werden, ohne auf konstruktive Belange tiefer einzugehen. Dies konnte Gegenstand einer weiteren Publikation sein. To understand the function of biological systems and their mathematical description is important in order to find new principles for technical applications. In this paper, the possibility of the description and the simulation of a Spider Leg Locomotion System using a Rigid Body System with hydraulic drive is presented. The transformation of the biological and design principles to technical systems including microsystems is demonstrated on a gripper. There, however, only the principal possibility to realize a gripper on the model of a spider leg is presented without going into more details how to design such a gripper. This might be the subject of a forthcoming paper.

Crawling at High Speeds: Steady Level Locomotion in the Spider Cupiennius salei-Global Kinematics and Implications for Centre of Mass Dynamics.

TL;DR: Analysis of a large dataset concerning global kinematics and the implications for dynamics of adult female specimens of the large Central American spider Cupiennius salei revealed specific characteristics of velocity dependent changes in the movements of the individual legs, as well as in the translational and rotational degrees of freedom of both the centre of mass and the body.

Jumping kinematics in the wandering spider Cupiennius salei.

TL;DR: In this paper, the authors observed two different types of jumps following a disturbance: prepared and unprepared jumps, in which the animals could jump in any direction away from the disturbance and demonstrated remarkable directional flexibility by flexing the legs on the leading side and extending them on the trailing side.

Enhanced Flexible Fluidic actuators for biologically inspired lightweight robots with inherent compliance

TL;DR: The new manufacturing process allows applying the biomimetic spider leg approach even for structural robotic links with variable stiffness, and in order to exploit the potential of FFAs a compliant mechanism with integrated position sensor was developed.

On Technomorphic Modelling and Classification of Biological Joints

TL;DR: Biological rigid-body joints (diarthroses) show some similarities to technical joints, but occur in fewer basic variants, and to enable the transfer of explanatory techniques, biomechanics and engineering need a shared terminology.
