iRobot® Create® 3 Simulator

Testing License

This is a ROS 2 simulation stack for the iRobot® Create® 3 robot. Both Ignition Gazebo and Classic Gazebo are supported.

Have a look at the Create® 3 documentation for more details on the ROS 2 interfaces exposed by the robot.

Prerequisites

Required dependencies:

  1. ROS 2 galactic
  2. ROS 2 dev tools:

Besides the aforementioned dependencies you will also need at least one among Ignition Gazebo and Classic Gazebo

Classic Gazebo

Install Gazebo 11

Ignition Edifice

sudo apt-get update && sudo apt-get install wget
sudo sh -c 'echo "deb http://packages.osrfoundation.org/gazebo/ubuntu-stable `lsb_release -cs` main" > /etc/apt/sources.list.d/gazebo-stable.list'
wget http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -
sudo apt-get update && sudo apt-get install ignition-edifice

Build

  • Create a workspace if you don't already have one:
mkdir -p ~/create3_ws/src
  • Clone this repository into the src directory from above.

  • Use vcs to clone additional dependencies into the workspace:

vcs import ~/create3_ws/src/ < ~/create3_ws/src/create3_sim/dependencies.repos
  • Navigate to the workspace and install ROS 2 dependencies with:
cd ~/create3_ws
sudo apt-get update
rosdep install --from-path src -yi
  • Build the workspace with:
export IGNITION_VERSION=edifice
colcon build --symlink-install
source install/local_setup.bash

Run

Classic Gazebo

Empty world

Create® 3 can be spawned in an empty world in Gazebo and monitored through RViz with

ros2 launch irobot_create_gazebo_bringup create3_gazebo.launch.py
AWS house

Create® 3 can be spawned in the AWS small house in Gazebo and monitored through RViz. This requires that the package aws_robomaker_small_house_world is available.

If you need it, you can build aws_robomaker_small_house_world in your ROS 2 workspace by doing:

vcs import ~/create3_ws/src/ < ~/create3_ws/src/create3_sim/irobot_create_gazebo/demo.repos
cd ~/create3_ws
colcon build --symlink-install
source install/local_setup.bash

Then you can run:

ros2 launch irobot_create_gazebo_bringup create3_gazebo_aws_small.launch.py

Ignition Gazebo

Create® 3 can be spawned in a demo world in Ignition and monitored through RViz with

ros2 launch irobot_create_ignition_bringup create3_ignition.launch.py
