Introduction

Autonomous vehicles have revolutionized the transportation industry with their ability to navigate through complex environments without human intervention. One of the key components of an autonomous vehicle is its ability to track lanes and recognize signs, which is crucial for safe and efficient navigation. In this article, we will discuss the simulation environment for an autonomous vehicle that can perform lane tracking using ROS (Robot Operating System).

Background

ROS is a widely used open-source software framework for building robot applications. It provides a set of tools and libraries that enable developers to create complex robot systems. Gazebo, a popular robotics simulator, is often used in conjunction with ROS to simulate robot environments. However, Carla, another popular simulator, takes up a lot of space and requires a high-performance computer to run smoothly.

Requirements for a Simulation Environment

When selecting a simulation environment for an autonomous vehicle, there are several key requirements to consider:

Realism: The simulation environment should be able to accurately simulate real-world scenarios, including road conditions, weather, and traffic.
Flexibility: The simulation environment should be able to accommodate different types of autonomous vehicles and scenarios.
Scalability: The simulation environment should be able to handle large-scale simulations with multiple vehicles and scenarios.
Ease of use: The simulation environment should be easy to set up and use, with a user-friendly interface and minimal technical expertise required.

Simulation Environment Options

There are several simulation environment options available for autonomous vehicles, including:

Gazebo: Gazebo is a popular robotics simulator that is widely used in conjunction with ROS. It provides a realistic simulation environment that can be customized to meet the needs of an autonomous vehicle project.
