RMIT Driverless Simulator.

Based upon CAT vehicle simulator, see below for details.
To use as is of 26/8/2020,
1: install cat vehicle sim as below
2: download this repository onto your desktop
3: Open files in ubuntuand use the command (CTRL+H) to see hidden folders.
4. Navigate to ~/Home/.gazebo/models/
5: Open a new tab in files (CTRL+T) and navigate to the dowloaded repository
6: In the tracks folder, copy all folders (acceleration, big_track, skidpad, small_track)
7. Paste these in ~/Home/.gazebo/models/
8: now copy the 'urdf', 'worlds', 'meshes' and 'launch' folders from the downloaded depository
9: paste them in 'your_workspace'/src/catvehicle and overwrite the folders that are named identicly, you may need to delete them first 10: use the comand, sudo apt-get install ros-melodic-velodyne-gazebo-plugins 11: use the command sudo apt-get install ros-melodic--hector-gazebo-plugins 12: you should be good to launch them now

Launching and running model with gazebo:

1: Open a terminal and run, $ roscore
2: In a new terminal window or tab (CTRL+shift+t) run $ roslaunch catvehicle catvehicle_big_track.launch
2a: other tracks include, $ roslaunch catvehicle catvehicle_small_track.launch
$ roslaunch catvehicle catvehicle_skidpad.launch
$ roslaunch catvehicle catvehicle_acceleration.launch
3: In a new terminal run $ gzclient
4: This will open gazebo, click on gazebo and the model should be in the enviroment you launched

optional

5: To move the vehicle open a new terminal and run $ rosrun telop_twist_keyboard telop_twist_keyboard.py /cmd_vel:=/catvehicle/cmd_vel
5a: This window must be open and currently clicked on to recieve keystrokes. speed is very slow to begin so hold q to increase speed.
6: To view cameras and lidar data and to visualise it use $ rosrun rviz rviz
6a: In rvis set Fixed Frame to catvehicle/odom, and use add to add lidar or cameras from topic menu. To add the robot use add and select RobotModel from 'By Display Type'. Then change Robot Description to catvehicle/robot_description and TF Prefix to catvehicle

Cognitive and Autonomous Test Vehicle (CAT Vehicle) Testbed

The CAT Vehicle is a ROS based simulator to facilitate the development of autonomous vehicle applications. This repository houses the files that utilize the Gazebo simulator, and additional interfaces to the physical CAT Vehicle Testbed available at the University of Arizona - Department of Electrical and Computer Engineering.

Dependencies

• ROS
• obstaclestopper
• control_toolbox
• sicktoolbox
• sicktoolbox_wrapper
• stepvel
• cmdvel2gazebo
• Controller manager (allows the car to move around with ROS messages)

  sudo apt-get install ros-melodic-controller-manager
  sudo apt-get install ros-melodic-ros-control ros-melodic-ros-controllers
  sudo apt-get install ros-melodic-gazebo-ros-control

System Requirements

• Ubuntu 18.04 LTS (We cannot guarantee if it works on any other version of Ubuntu)
• RAM: 4GB required, > 8GB recommended.

What's new

• Released for Ubuntu 18.04 LTS, ROS Melodic and Gazebo 9.0
• Support for front camera
• More stable vehicle dynamics
• Bug fixes and improvements

How to use it

Installing ROS

• Follow the steps mentioned in the ROS wiki page on how to install ROS Melodic.
• In addition to that we are required to install some additional ros packages

sudo apt-get install ros-melodic-velodyne ros-melodic-novatel-span-driver

Creating catkin workspace

In order to use the catvehicle ROS package, you should work within a catkin workspace. If you do not already have one:

cd ~
mkdir -p catvehicle_ws/src
cd catvehicle_ws/src
catkin_init_workspace
cd ..
catkin_make

At this point, you can extract this release package from catvehicle-3.0.1 and other dependent package into your src directory

cd ~/catvehicle_ws/src
git clone https://github.com/jmscslgroup/catvehicle
git clone https://github.com/jmscslgroup/obstaclestopper
git clone https://github.com/jmscslgroup/control_toolbox
git clone https://github.com/jmscslgroup/sicktoolbox
git clone https://github.com/jmscslgroup/sicktoolbox_wrapper
git clone https://github.com/jmscslgroup/stepvel
git clone https://github.com/jmscslgroup/cmdvel2gazebo
cd ..
catkin_make

Sourcing workspace to the environment path

echo "source ~/catvehicle_ws/devel/setup.bash" >> ~/.bashrc

Simple tutorial and examples

Follow the tutorials on the CAT Vehicle Testbed group on the CPS Virtual Organization to see how to use the testbed.
