SD Twizy Vehicle Simulation

Gazebo simulation packages for the SD Twizy vehicle


- Ubuntu 16.04 LTS
- ROS Kinetic ros-kinetic-desktop-full
- Catkin Command Line Tools catkin_tools
- Gazebo ros-kinetic-gazebo-ros-pkgs

This model has been tested with Gazebo 7.14.0. Run gazebo --version to make sure you have the correct version installed.
To update to Gazebo 7.14.0, do:

sudo sh -c 'echo "deb `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'
wget -O - | sudo apt-key add -
sudo apt update && sudo apt upgrade
- ROS packages:
sudo apt-get install ros-kinetic-joint-state-publisher ros-kinetic-robot-state-publisher ros-kinetic-ackermann-msgs ros-kinetic-ros-control ros-kinetic-ros-controllers ros-kinetic-twist-mux ros-kinetic-joy ros-kinetic-controller-manager ros-kinetic-robotnik-msgs ros-kinetic-velodyne-simulator ros-kinetic-effort-controllers ros-kinetic-velocity-controllers ros-kinetic-joint-state-controller ros-kinetic-gazebo-ros-control

Setup your workspace:

A. Create a catkin workspace:

source /opt/ros/kinetic/setup.bash
mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/
catkin build
source devel/setup.bash

For more information, visit create_a_workspace

B. Initialize your catkin workspace:

Navigate to the root of your catkin workspace, if you are not already with cd ~/catkin_ws. Initialize your workspace:

catkin init

C. Clone this repository or copy its contents at your ~/catkin_ws/src folder of the catkin workspace you just initialized.

D. Navigate to your workspace and build the simulation

cd ~/catkin_ws
catkin build sd_robot sd_control

If you have previously built your workspace with catkin_make: Either clean your workspace with catkin clean and rebuild with catkin build or build the SD Twizy Gazebo packages in isolation with catkin_make --pkg sd_robot sd_control. After the built has successfully finished, do:

source devel/setup.bash

E. Launch the simulation:

This launches the vehicle model in Gazebo and RViz for visualizing the sensors' output.

roslaunch sd_robot sd_twizy_empty.launch

You might need to update your ignition-math version sudo apt upgrade libignition-math2

Display the robot only in Gazebo:

To only launch the model in Gazebo, do:

roslaunch sd_robot sd_twizy_empty_gazebo.launch 
Known Issues:
  • On Gazebo7 the model logs an error on the p-gain of the wheels' velocity controllers. This does not affect the performance of the model and has only been detected when running the gazebo-ros-control package for Gazebo7. If you choose to build and run the model in Gazebo8 with gazebo8-ros-control, the problem disappears.

Controlling the Robot:


The robot supports the generic Linux joystick controllers.
To publish the cmd_vel topic [geometry_msgs/Twist], clone or copy the contents of the ROS package teleop_twist_joy at the ~/catkin_ws/src folder of your catkin workspace. Then build the package by doing catkin build or catkin_make, depending on what you previously used to build the simulation model. After you have built the package, do: source devel/setup.bash
To launch the controller, do roslaunch teleop_twist_joy teleop.launch

A. Microsoft Xbox 360 Controller for Linux:

To control the vehicle, keep the Xbox Guide button pressed (Index 8) and use the Left Stick (Index 9) to navigate

B. Logitech Wireless Gamepad F710 (DirectInput Mode):

To control the vehicle, keep the Back button (Index 8) pressed and use the Start button (Index 9) to navigate


To install the ROS package teleop_twist_keyboard, do: sudo apt-get install ros-kinetic-teleop-twist-keyboard.
To launch the ROS package, do: rosrun teleop_twist_keyboard


Autoware is a ROS-based open-source software, enabling self-driving mobility to be deployed in open city areas. For more information you can visit the wiki page Autoware publishes the twist_cmd topic geometry_msgs/TwistStamped

Display the robot only in rviz:

First, make sure you have rviz installed, by doing:

cd ~/catkin_ws

If you don't have rviz installed, do sudo apt-get install ros-kinetic-rviz*.
The configuration file of the SD Twizy is located at ~/catkin_ws/src/streetdrone_model/sd_robot/config/sd_twizy.rviz
