In Robotic Operating System (ROS) and robot simulator Gazebo, there is no official package to simulate the Ackerman motion. The existing open-source github was build over many sources and it is outdated. Furthermore, the package could not be run in the latest version of ROS. It gave the compilation errors due to the non-compatibility of versions.
We manage to update our Github repo with the latest version that works with the current version of ROS based on the previous research works. Melodic and Noetic were tested by our team.
The repaired version was uploaded to our Github. You can download it and improvise it if you want. Please provide a pull request just in case you have an improved version of the code.
Since most of the previous repo used previous version of ROS, I faced compilation error in ROS Noetic version running Ubuntu 20.04. Some of the launch file issues due to the newer ROS version affected the launch file. The issue can be seen here:
ROS packages for simulating a vehicle with Ackermann steering
cd ~/catkin_ws/src
git clone https://github.com/aizzat/ackermann_vehicle/
sudo apt install ros-noetic-ackermann-msgs
cd ~/catkin_ws
rosdep install --from-paths src --ignore-src -r -y
catkin_make
cd ~/catkin_ws/src
git clone https://github.com/aizzat/ackermann_vehicle/
sudo apt install ros-melodic-ackermann-msgs
cd ~/catkin_ws
rosdep install --from-paths src --ignore-src -r -y
catkin_make
roslaunch ackermann_vehicle_gazebo ackermann_vehicle_noetic.launch
#go to terminal to this python directory:
#/ackermann_vehicle/ackermann_vehicle_navigation/scripts/
# /ackermann_vehicle/ackermann_vehicle_navigation/scripts$
# Run the following commands:
./cmd_vel_to_ackermann_drive.py
This python file will wait for /cmd_vel inputs. You can test it with another terminal. For example:
rostopic pub -r 10 /cmd_vel geometry_msgs/Twist '{linear: {x: 0.1, y: 0.0, z: 0.0}, angular: {x: 0.0,y: 0.0,z: 0.2}}'
