Getting Started

The guide outlines the steps required to setup Apollo for use with the LG Automotive Simulator. If you have not already set up the simulator, please do so first by following the instructions here.

We use our forked version of the Apollo repository, which can be found here.

The software and source code in this repository are intended only for use with LG Automotive Simulator and should not be used in a real vehicle.

Prerequisites

  • Linux operating system (preferably Ubuntu 14.04 or later)
  • Nvidia graphics card (required for Perception)
    • Nvidia proprietary driver must be installed
    • The current version of Apollo does not support Volta and Turing architectures (this includes Titan V and RTX 2080 GPUs).

Setup

Docker

Apollo is designed to run out of docker containers. The image will mount this repository as a volume so the image will not need to be rebuilt each time a modification is made.

Installing Docker CE

To install Docker CE please refer to the official documentation. We also suggest following through with the post installation steps.

Installing Nvidia Docker

Before installing nvidia-docker make sure that you have an appropriate Nvidia driver installed. To test if nvidia drivers are properly installed enter nvidia-smi in a terminal. If the drivers are installed properly an output similar to the following should appear.

The installation steps for nvidia-docker are available at the official repo.

Pulling LGSVL Docker image

LGSVL maintains a docker image to be used alongside this repository. The docker image is available here.

To pull the image use the following command:

docker pull lgsvl/apollo

Cloning the Repository

This repository includes a couple of submodules for HD Maps and rosbrige. To make sure that the submodules are also cloned use the following command:

git clone --recurse-submodules git@github.com:lgsvl/apollo.git

Building Apollo and rosbridge

Now everything should be in place to build apollo. Apollo must be built from the container. To launch the container navigate to the directory where the repository was cloned and enter:

./docker/scripts/dev_start.sh

This should launch the container and mount a few volumes. It could take a few minutes to pull the latest volumes on the first run.

To get into the container:

./docker/scripts/dev_into.sh

Build Apollo:

./apollo.sh build_gpu

(optional) to build without gpu:

./apollo.sh build

Now build rosbrige:

cd ros_pkgs
catkin_make

Launching Apollo alongside the simulator

Here we only describe only a simple case of driving from point A to point B using Apollo and the simulator.

To launch apollo, first launch and enter a container as described in the previous steps.

  • To start Apollo:

    ./scripts/bootstrap.sh
    

    Note: you may receive errors about dreamview not being build if you do not run the script from the /apollo directory.

  • Launch rosbridge:

    ./scripts/rosbridge.sh
    
  • Run the LG SVL Simulator (see instructions in the simulator repository)

    • Select the San Francisco map and the XE-Rigged-apollo vehicle.
    • Enable GPS, IMU, LIDAR, HD Mode, and Telephota Camera.
    • (optional) Enable traffic.
  • Open Apollo dreamview in a browser by navigating to: localhost:8888

    • Select the LG SVL 1080 vehicle and San Francisco map in the top right corner.
    • Open the Module Controller tap (on the left bar).
    • Enable Localization, Perception, Planning, Prediction, Routing, and Control.
    • Navigate to the Route Editing tab.
    • Select a destination by clicking on a lane line and clicking Submit Route.
    • Watch the vehicle navigate to the destination.
    • To stop the docker container run the dev_stop.sh script in apollo/docker/scripts in a new terminal (not in the docker container).
