Dynamics of underwater inspection robot

Abstract

In this article authors present the problems connected with the dynamics modeling mobile robot with crawler drive. The description of the robot’s dynamic is based on the energetic method based on Lagrange equations. In order to avoid modeling problems connected with decoupling Lagrange multipliers Maggi equations are used. During the analysis and motion simulation takes into account such parameters as: slipping track-dependent deformation of the substrate and claws, strength, buoyancy robot located in the liquid, the hydrodynamic resistance force depending on the environment in which the robot works and the strength of the rolling resistance of track. Simulations of the dynamics parameters have been made and the results are shown.
