Cosserat Rod Modeling of Continuum Robots from Newtonian and Lagrangian Perspectives

نویسندگان

چکیده

Cosserat rod theory proved efficient modeling performances in robotics, especially the context of continuum robots, past decade. The implementation such is far from being unique and straightforward. We consider illustrative example multisegment, general routing tendon actuated robots their nominal static operating regime. This article details two main approaches based on modeling, namely, Newtonian Lagrangian approaches. provide a walk-through guide regarding theoretical derivations numerical both approaches, together with proof equivalence. comparative study supplemented novel contributions extensions each approach in-depth discussion applicability, as well highlighting special features.

Mechanics Modeling of Multisegment Rod-Driven Continuum Robots

This paper presents a novel modeling approach for the mechanics of multisegment, roddriven continuum robots. This modeling approach utilizes a high-fidelity lumped parameter model that captures the variation in curvature along the robot while simultaneously defined by a discrete set of variables and utilizes the principle of virtual power to formulate the statics and dynamics of the continuum r...

three-dimensional modeling of strain localization in cosserat continuum theory

in this paper, a higher order continuum model is presented based on the cosserat continuum theory in 3d numerical simulation of shear band localization. as the classical continuum models suffer from the pathological mesh-dependence in strain softening models, the governing equations are regularized by adding the rotational degrees-of-freedom to conventional degrees-of-freedom. the fundamental r...

Variational Analysis of the Coupling Between a Geometrically Exact Cosserat Rod and an Elastic Continuum

We formulate the static mechanical coupling of a geometrically exact Cosserat rod to a nonlinearly elastic continuum. In this setting, appropriate coupling conditions have to connect a one-dimensional model with director variables to a three-dimensional model without directors. Two alternative coupling conditions are proposed, which correspond to two different configuration trace spaces. For bo...

Shape Modeling of Continuous-Curvature Continuum Robots

An essential problem in developing concentric-tube continuum robots is to determine the shape of the robot, which is dependent on robot structure and external load. A comprehensive model that takes into considerations of influencing factors is hence required. In this work, the shape modeling of a type of concentric-tube continuum robot built with a collection of super-elastic NiTiNol tubes is s...
