ISAR implementation for the Turtlebot3 Waffle Pi.
ISAR - Integration and Supervisory control of Autonomous Robots - is a tool for integrating robot applications into Equinor systems. Through the ISAR API you can send command to a robot to do missions and collect results from the missions.
Running the full ISAR system requires an installation of a robot which satisfies the required interface. isar-turtlebot is an ISAR implementation of the Turtlebot3 Waffle Pi, which enables running the Turtlebot with ISAR through simulations or physically.
- git
- docker
- docker-compose
NOTE: Docker must NOT be installed using Snap. The Snap version is not compatible with nvidia-docker2. Instead, follow the official documentation from Docker for installation.
To check if your Docker version was installed using snap, run the following command
systemctl list-units --type=service | grep docker
If the result is snap.docker.dockerd.service
, the installation has been done using snap and docker must be reinstalled.
- Install the newest recommended drivers from Nvidia if not already as described by the following documentation
- Install nvidia-docker2 using the official documentation
Build the container. This needs to be done once before one can give the container access to the screen.
docker-compose build
Give the docker container access to the screen, this needs to be done each time the computer is restarted.
xhost +local:`docker inspect --format='{{ .Config.Hostname }}' turtle_sim`
Start the simulation
docker-compose up
To build and start the simulation
docker-compose up --build
The simulation world that is used can be set by changing the world variable in the 'entrypoint.sh' file.
Additional settings, such as using Nvidia GPU or gamepad input to the docker container is included via separate .yml-files. To run the docker container with these settings the corresponding docker-compose-setting.yml
file must be spesified together with the main docker-compose.yml
file. Several setting files can be included.
docker-compose -f docker-compose.yml -f docker-compose-setting.yml up --build
To run the simulation in headless mode set the environment variable HEADLESS=true
prior to launching the docker container. Alternatively directly as an environment variable in the docker-compose command:
HEADLESS=true docker-compose up --build
The simulation can then be viewed at webviz with the following link: https://webviz.io/app/?rosbridge-websocket-url=ws://localhost:9090/
A video stream of the front camera is found on the address
http://localhost:5000/stream_viewer?topic=/camera/rgb/image_raw
New models can be added by placing the model that is used by Gazebo into '/models/new_world/' and adding a "new_world.world" file into 'ros_packages/isar_turtlebot/worlds/'. The map that is used by the planner should be placed into '/ros_packages/isar_turtlebot/maps/' with the name 'new_world.*'. To add a default configuration for the initial pose and position of the robot in the simulation, add '/config/new_world.cfg' with the desired parameters.
To run the simulation with the custom model, set WORLD_NAME=new_world
in docker_scripts/entrypoint.sh
.
The simulator requires a computer or a virtual machine running Ubuntu. The turtlebot simulator works with different ROS/gazebo distributions, but this installation guide is based on ROS noetic
. To install and run the turtlebot simulator, you will need to install ROS noetic on your computer. The desktop
version should be sufficient.
Then, install dependent ROS packages, and the simulation package.
You also need to install gazebo with a version corresponding to your ROS distribution:
sudo apt-get install gazebo11
The installation can be verified by running:
gazebo
Install the required ROS packages for gazebo:
sudo apt-get install ros-noetic-gazebo-ros-pkgs ros-noetic-gazebo-ros-control
First, you will need to set the following environment variables:
export ISAR_TURTLEBOT_PATH=<path/to/isar-turtlebot>
export TURTLEBOT3_MODEL=waffle
Build with catkin_make:
cd ~/catkin_ws && catkin_make
You will need a map (map.pgm
and map.yaml
). The map can be generated, or the example map can be used.
The gazebo together with the navigation stack and rosbridge is then launched by:
roslaunch launch/simulation.launch
The robot can be located with 2DPose Estimate
and naviagted with 2D Navigation Goal
in rviz.
Download and install ISAR on your computer. Follow the robot integration guide installing isar-turtlebot
. Remember to set the robot directory environment variable:
export ISAR_ROBOT_PACKAGE=isar_turtlebot
For the ISAR API to communicate with the simulator, you will need rosbridge:
sudo apt-get install ros-noetic-rosbridge-suite
You can now run the simulation and launch rosbridge:
roslaunch rosbridge_server rosbridge_websocket.launch
To run ISAR:
python main.py
Missions can be posted to the robot through ISAR.
If the example map are used, you can try the example mission number 2
.
The turtlebot base can be controlled manually by publishing to the ros topic /cmd_vel
. Using a keyboard, the ros package teleop_twist_keyboard translates keyboard inputs to ros messages. Similarly, the ros package teleop_twist_joy handles joystick messages.
With the simulation running, open a new terminal. If running in docker, access the docker container with:
docker exec -it isar_turtlebot bash
Install the teleoperation package (if running in docker this package must be installed every time):
sudo apt-get install ros-noetic-teleop-twist-keyboard
With the teleoperation package installed, enable it with:
rosrun teleop_twist_keyboard teleop_twist_keyboard.py
Teleoperating with a joystick requires an additional package, joy, for reading the joystick input and publishing it to a topic. This package should be compatible with any joystick supported by Linux. After you connected the joystick it should be found as an input decvice /dev/input/jsX
, where X is the unique id-number of the joystick (default js0
).
To verify if the joystick is setup correctly, find the unique id-number with
ls /dev/input/
and run
jstest /dev/input/jsX.
To enable teleoperation with a joystick while running in docker the joystick must be added as a device in docker-compose.yaml
. This is done by including the docker-compose-gamepad.yaml
file as decribed in the docker section. Additionally the environment variable TELEOP_CONTROLLER
must be specified(currently "xbox"
is the only supported controller):
TELEOP_CONTROLLER="xbox" docker-compose -f docker-compose.yml -f docker-compose-gamepad.yml up --build
To enable teleoperation while running locally, first install the two packages:
sudo apt-get install ros-noetic-joy ros-noetic-teleop-twist-joy
Enable teleoperation by opening two new terminals and start up joy_node
and teleop_node
:
rosrun joy joy_node
rosrun teleop_twist_joy teleop_node
To control the turtlebot, hold in enable_button
and use the joystick. See documention for teleop_twist_joy for more information.
The turtlebot can be equipped with a manipulator which also can be included in the simulations. Additional software must be installed for the manipulator simulation.
cd ~/catkin_ws/src/ &&
git clone https://github.com/ROBOTIS-GIT/turtlebot3_manipulation.git &&
git clone https://github.com/ROBOTIS-GIT/turtlebot3_manipulation_simulations.git &&
git clone https://github.com/ROBOTIS-GIT/open_manipulator_dependencies.git &&
cd ~/catkin_ws && catkin_make
The manipulator can be controlled using rviz or a simpler GUI which is enabled by setting the roslaunch argument
MANIPULATOR_GUI
to "rviz"
or "simple"
respectively. With the latter as default value. There is no constraints for running both controllers simultaneously, but such functionality is not implemented. Running simulation with manipulator can be done by the roslaunch command with the prerequisite of having isar-turtlebot installed as a ros package.
roslaunch isar-turtlebot turtlebot_manipulator.launch open_manipulator_gui:=true
Alternatively the simulation with manipulator can also run in docker by including the parameter ENABLE_MANIPULATOR
and the controller GUI set according to the description above:
sudo ENABLE_MANIPULATOR=true MANIPULATOR_GUI="rviz" docker-compose up --build
The simulation can also run in docker as described in the section for docker.
Teleoperating the manipulator during simulation is enabled with the roslaunch argument TELEOP-CONTROLLER
specifying the controller (currently 'xbox'
is the only supported controller).
roslaunch isar_turtlebot turtlebot_manipulator.launch teleop_controller:="xbox"
To run simulation in docker with teleoperation of manipulator:
sudo ENABLE_MANIPULATOR=true MANIPULATOR_GUI="rviz" TELEOP_CONTROLLER="xbox" docker-compose -f docker-compose.yml -f docker-compose-setting.yml up --build
