Introduction

In this article, we will delve into the world of Ardupilot rover simulation, specifically focusing on setting up a simulation for an ackermann-steering rover with additional sensors. We will explore the process of creating a simulation environment using Gazebo and Ardupilot, and provide a step-by-step guide on how to set up and run the simulation.

Background

Ardupilot is an open-source autopilot system for drones, multicopters, and ground vehicles. It provides a robust and flexible platform for developing and testing autonomous systems. Gazebo is a popular simulation environment for robotics and autonomous systems, allowing users to create and simulate complex scenarios.

Setting Up the Simulation Environment

To set up the simulation environment, we will need to install the following packages:

Gazebo: A simulation environment for robotics and autonomous systems.
Ardupilot: An open-source autopilot system for drones, multicopters, and ground vehicles.
ROS2: A robotics operating system for developing and testing autonomous systems.

We will use the following tools to set up the simulation environment:

ROS2: To install and configure the simulation environment.
Gazebo: To create and simulate the rover environment.
Ardupilot: To configure and run the autopilot system.

Step 1: Install ROS2 and Gazebo

To install ROS2 and Gazebo, follow these steps:

Install ROS2

sudo apt-get update
sudo apt-get install ros-foxy-desktop

Install Gazebo

sudo apt-get install gazebo9

Step 2: Install Ardupilot

To install Ardupilot, follow these steps:

Clone the Ardupilot Repository

git clone https://github.com/ardupilot/ardupilot.git

Build and Install Ardupilot

cd ardupilot
mkdir -p build
cd build
cmake ..
make
sudo make install

Step 3: Configure the Simulation Environment

To configure the simulation environment, we will need to create a new ROS2 package and add the necessary dependencies.

Create a New ROS2 Package

ros2 pkg create ardupilot_rover_simulation

Add Dependencies

ros2 pkg edit ardupilot_rover_simulation

Add the following dependencies to the package.xml file:

<depend>ros2_control</depend>
<depend>gazebo_ros</depend>
<depend>ardupilot</depend>

Step 4: Create the Simulation Environment

To create the simulation environment, we will need to create a new Gazebo world and add the necessary models.

Create a New Gazebo World

gazebo --world=rover_world.sdf

Add Models to the Gazebo World

gazebo --world=rover_world.sdf --model=rover_model.urdf

Step 5: Configure the Autopilot System

To configure the autopilot system, we will need to create a new Ardupilot configuration file and add the necessary settings.

Create a New Ardupilot Configuration File

touch ardupilot_config.yaml

Add Settings to the Ardupilot Configuration File

vehicle:
  type: rover
  steering: ackermann
  sensors:
    - name: lidar
      type: lidar
      topic: /lidar_data
    - name: camera
      type: camera
      topic: /camera_data

Step 6: Run the Simulation

To run the simulation, we will need to launch the ROS2 environment and start the Gazebo simulation.

Launch the ROS2 Environment

ros2 launch ardupilot_rover_simulation launch.py

Start the Gazebo Simulation

gazebo --world=rover_world.sdf

Conclusion

In this article, we have covered the process of setting up a Ardupilot rover simulation using Gazebo and ROS2. We have created a new ROS2 package, added dependencies, and configured the simulation environment. We have also created a new Gazebo world, added models, and configured the autopilot system. Finally, we have launched the ROS2 environment and started the Gazebo simulation.

Future Work

In the future, we plan to add more features to the simulation environment, such as:

Sensor Simulation: We plan to add sensor simulation to the simulation environment, allowing users to test and validate their sensor algorithms.
Autopilot System: We plan to add more features to the autopilot system, such as navigation and control.
User Interface: We plan to add a user interface to the simulation environment, allowing users to easily interact with the simulation.
