The ROS bridge enables two-way communication between ROS and CARLA. The ROS bridge enables two-way communication between ROS and CARLA.
In order to do so, the information from the CARLA server is translated to ROS topics. For example, the information retrieved by sensors is structured to fit ROS structure. In order to do so, the information from the CARLA server is translated to ROS topics. For example, the information retrieved by sensors is structured to fit ROS messages.
And also vice versa, the messages sent between nodes in ROS get translated to commands to be applied in CARLA. This is commonly used to update the state of a vehicle and apply controllers.

## Setting CARLA ## Setting CARLA
There is some configuration for CARLA available from the ROS bridge. This can be setup by editing the file: [`share/carla_ros_bridge/config/settings.yaml`](https://github.com/carla-simulator/ros-bridge/blob/master/carla_ros_bridge/config/settings.yaml). Settings can be changed, in order to modify the way CARLA works along with the ROS bridge, by editing the file: [`share/carla_ros_bridge/config/settings.yaml`](https://github.com/carla-simulator/ros-bridge/blob/master/carla_ros_bridge/config/settings.yaml).
