Abb. 1 AlphaBot Simulation in Webots

Introduction

In order to simulate, a 3D model of a 4 wheeled robot is created inside Webots first. That robot is simulated with a controller which is written in C inside the text editor of Webots. That robot is later imported in Webots in Ubuntu and customised with a servo, an ultrasonic sensor and a caster wheel to resemble the Alphabot robot of our project. Finally, it is programmed with ROS2 and it runs in Webots as an obstacle avoiding robot.

Creation of a 3D Model of a 4-Wheeled-Robot in Webots

Abb. 2 - 3D view of 4-Wheeled-Robot

A robot is created in Webots from scratch by following the tutorial 6 in Cyberbotics. The robot consistes of a body, 4 wheels and two distance sensors(IR sensors). The figure above shows the 3D view of the end result.
