The Challenging Task of Developing Autonomous Robots
Developing autonomous robots is a complex and demanding process. It requires the development, integration, and testing of both hardware and software components. However, conducting these tasks in a physical environment can be difficult and expensive. Simulations offer a solution by allowing robot developers to quickly test their code, iterate multiple times, and finally deploy the software to real-world hardware for testing.
One of the key requirements for robot simulations is high-fidelity rendering. Open 3D Engine (O3DE) is an open-source simulator that provides the realistic rendering needed for robotic simulations. It is a community-driven 3D engine that is capable of creating and running realistic 3D worlds for gaming. O3DE utilizes a configurable, multi-threaded rendering engine called Atom, which supports features like physically based rendering, ray-tracing, and post-processing.
O3DE also includes a physics engine based on Nvidia PhysX, allowing for the simulation of real-world physics. The engine is designed with a modular system architecture known as the Gems system. This allows developers to select and configure various packages (Gems) based on their project’s specific needs. These Gems can come from the O3DE project itself, third-party providers, or custom-made.
Recently, O3DE introduced the ROS 2 gem, enabling it to work seamlessly with robotics simulations that use the Robotic Operating System (ROS). This integration allows robotics developers to test and train perception models in a simulation environment that closely resembles the real world. Moreover, to expedite the development cycle, simulations can be scaled by running them in parallel in the cloud.
Running simulations in the cloud provides several advantages, including improved performance, cost effectiveness, and scalability. AWS RoboMaker supports GPU-based simulation jobs by running simulators in OCI compliant containers, such as Docker. In this tutorial, we will demonstrate how to create a Docker image from an O3DE sample application (Robot Vacuum Sample) and deploy it as a simulation job in AWS RoboMaker.
Prerequisites
Before we begin, please ensure you have an AWS account with Amazon ECR and AWS RoboMaker access IAM permissions. Additionally, you’ll need a development system or an AWS Cloud9 development environment with the following requirements:
– Linux Ubuntu 20.04 or 22.04
– At least 60 GB of free disk space
– AWS CLI and Docker engine installed
Step-by-Step Guide
Build the Container Images
To start, we need to build the container images for the Robot Vacuum Sample application. The application includes a Dockerfile that specifies the build process for both the simulation and navigation stack.
1. Set the environment variable for the workspace folder.
“`
export WORKSPACE=$HOME/o3de-sample
“`
2. Clone the Robot Vacuum Sample application repository.
“`
mkdir -p $WORKSPACE
git clone $WORKSPACE/RobotVacuumSample
“`
3. Build the simulation docker image named “o3de_robot_vacuum_simulation”.
“`
cd $WORKSPACE/RobotVacuumSample/Docker
docker build –build-arg IMAGE_TYPE=simulation -t o3de_robot_vacuum_simulation .
“`
4. Build the navigation stack docker image named “o3de_robot_vacuum_navstack”.
“`
cd $WORKSPACE/RobotVacuumSample/Docker
docker build –build-arg IMAGE_TYPE=navstack -t o3de_robot_vacuum_navstack .
“`
Note: Ensure that your environment meets the minimum O3DE hardware requirements before running these docker containers.
Build and Push the AWS RoboMaker Container Images to Amazon ECR
The container images we created are designed to run locally on a Linux host machine. To run them on AWS RoboMaker, we need to install the NICE DCV plugins on the container images.
1. Extend the simulation docker image to enable NICE DCV by creating the file “$WORKSPACE/Dockerfile.simulation.robomaker”.
“`
FROM o3de_robot_vacuum_simulation:latest
ENV WORKSPACE=/data/workspace
WORKDIR $WORKSPACE
ENV DEBIAN_FRONTEND=noninteractive
ENV LAUNCH_FULLSCREEN_OPT=1
# Install NICE DCV
(RUN wget)
(RUN gpg –import NICE-GPG-KEY)
(RUN wget)
(RUN tar -xvzf nice-dcv-2023.0-15487-ubuntu2204-x86_64.tgz
&& mkdir -p /etc/modprobe.d
&& apt-get install -y /data/workspace/nice-dcv-2023.0-15487-ubuntu2204-x86_64/nice-dcv-server_2023.0.15487-1_amd64.ubuntu2204.deb
/data/workspace/nice-dcv-2023.0-15487-ubuntu2204-x86_64/nice-dcv-gl_2023.0.1039-1_amd64.ubuntu2204.deb
/data/workspace/nice-dcv-2023.0-15487-ubuntu2204-x86_64/nice-dcv-gltest_2023.0.318-1_amd64.ubuntu2204.deb)
# Install xterm for direct console access
RUN apt update && apt-get install -y xterm
“`
2. Build a new docker image named “o3de_robot_vacuum_simulation_robomaker”.
“`
docker build -t o3de_robot_vacuum_simulation_robomaker -f $WORKSPACE/Dockerfile.simulation.robomaker $WORKSPACE
“`
3. Create a repository in Amazon ECR for the new simulation docker image.
“`
aws ecr create-repository –repository-name o3de-robot-vacuum-simulation
“`
4. Set an environment variable for the simulation Amazon ECR repository using the repositoryUri from the JSON output.
“`
export ECR_SIMULATION_URI=000000000000.dkr.ecr.us-west-2.amazonaws.com/o3de-robot-vacuum-simulation
“`
5. Log into Amazon ECR from your local Docker runtime.
“`
aws ecr get-login-password | docker login –username AWS –password-stdin $ECR_SIMULATION_URI
“`
6. Tag the docker image “o3de_robot_vacuum_simulation_robomaker” with the repository URI.
“`
docker tag o3
