This is a C++ library which is used to interface messages between ROS and Apollo ecosystem. It is designed to help developers use ROS libraries to communicate with Apollo and hence make development easier.

Lidar Pointcloud received from Apollo , converted and published as a ROS message. {Left} Cyber_visualizer tool showing cyber pointcloud message. {Right} Rviz showing ros pointcloud message
There is a prebuild docker image which can be directly used. To use the prebuilt docker image:
cd docker_tools
./run.sh
To build the docker image on your machine,
cd docker_tools
./build.sh $image_name
If no image name is provided, it defaults to auroai/apollo_ros_bridge:latest
In order to build the bridge, first build the appropriate ros messages used in the bridge source code:
cd /home/apollo_ros_bridge/ros_pkgs
catkin build
source devel/setup.bash
Now, build the bridge source code using bazel. From the root workspace of the package,
cd /home/apollo_ros_bridge
bazel build cyber_ros_bridge:all
To run the example node, run
roscore && ./bazel-bin/cyber_ros_bridge/cyber_ros_bridge
for extra logging,
GLOG_v=4 GLOG_logtostderr=1 ./bazel-bin/cyber_ros_bridge/cyber_ros_bridge
This launches the bridge with default params (defined in the common folder).
Alternatively, to launch the bridge with custom parameters,
cyber_launch start cyber_ros_bridge/launch/bridge_example.launch
Run Apollo
Topics can be visualized with rostopic list and echo
Alternatively, publish relevant topics from ROS and view topics using cyber_monitor on Apollo's side
A sample script to run a ROS Container has been provided to help developers. This can be launched using:
cd /home/apollo_ros_bridge/docker_tools
./example_ros_run.shFor detailed information on how to add own bridging of topics, refer to adding custom bridging
The apollo ros bridge source code is released under the Apache License, Version 2.0
- Support for apollo 5.0
- Timer method for bridging
- easier docker setup
