AWS RoboMaker Sample Application - Hello World

This demonstrates the structure of a ROS project that works with RoboMaker by creating a robot spinning in an empty world.

RoboMaker sample applications include third-party software licensed under open-source licenses and is provided for demonstration purposes only. Incorporation or use of RoboMaker sample applications in connection with your production workloads or a commercial products or devices may affect your legal rights or obligations under the applicable open-source licenses. Source code information can be found here.

Requirements

• ROS Kinetic - Other versions may work, however they have not been tested
• Colcon - Used for building and bundling the application.

Build

Pre-build commands

sudo apt-get update
rosdep update

Robot

cd robot_ws
rosws update
rosdep install --from-paths src --ignore-src -r -y
colcon build

Simulation

cd simulation_ws
rosws update
rosdep install --from-paths src --ignore-src -r -y
colcon build

Run

Launch the application with the following commands:

• Running Robot Application on a Robot

  source robot_ws/install/local_setup.sh
  roslaunch hello_world_robot deploy_rotate.launch

• Running Robot Application Elsewhere

  source robot_ws/install/local_setup.sh
  roslaunch hello_world_robot rotate.launch

• Running Simulation Application

  source simulation_ws/install/local_setup.sh
  roslaunch hello_world_simulation empty_world.launch

Using this sample with RoboMaker

You first need to install colcon-ros-bundle. Python 3.5 or above is required.

pip3 install colcon-ros-bundle

After colcon-ros-bundle is installed you need to build your robot or simulation, then you can bundle with:

# Bundling Robot Application
cd robot_ws
source install/local_setup.sh
colcon bundle

# Bundling Simulation Application
cd simulation_ws
source install/local_setup.sh
colcon bundle

This produces the artifacts robot_ws/bundle/output.tar.gz and simulation_ws/bundle/output.tar.gz respectively. You'll need to upload these to an s3 bucket, then you can use these files to create a robot application,
create a simulation application, and create a simulation job in RoboMaker.
