Track: Manufacturing

Abstract

The present work is carried out on modelling robotics and analysis of rocker bogie mechanisms used in the mars rovers the main purpose of this project is to overcome the roughterrains while maintaining stability. This enables to have a suspension-based mechanism that distributes the vehicle load as evenly as possible even on bumps and irregular surfaces. The modelling of rocker bogie mechanisms is carried out by CATIA V5R20 and analysis it with ANSYS 19.2. A Rocker Bogie Mechanism is made completely from PVC pipe to increase its capability to withstand shock Vibration and mechanical failures. An android application is developed in order to communicate with the Arduino on the rover and can control the rover with mobile application. The important factor in manufacturing of rocker bogie mechanism is to determine the dimensions of rocker bogie linkages and angle between them. The lengths and angles of this mechanism can be changed as per requirement.The present work is carried out on modelling robotics and analysis of rocker bogie mechanisms used in the mars rovers the main purpose of this project is to overcome the roughterrains while maintaining stability.
