Introduction
To port ROS 1 to ROS 2, the ROS 1 Bridge tool can be used. This tool enables message communication between ROS 1 and ROS 2, allowing nodes from ROS 1 to communicate with nodes from ROS 2 and enabling the use of ROS 1 nodes in ROS 2.
Github: ros1-bridge
How To
Install
1. Install ros1(noetic) and ros2(foxy) on ubuntu 20.04.
2. Install ros1-bridge.
$ sudo apt-get install ros-foxy-ros1-bridge
Instructions
Dynamic_bridge
The dynamic_bridge will watch the available ROS 1 and ROS 2 topics, once a matching topic has been detected it starts to bridge the messages on this topic.
- If you want to establish a bidirectional bridge between ROS1 and ROS2, you can use
bridge-all-topics
$ ros2 run ros1_bridge dynamic_bridge --bridge-all-topics
- If you only want to establish ROS1 to ROS2 bridge, you can use
bridge-all-1to2-topics
$ ros2 run ros1_bridge dynamic_bridge --bridge-all-1to2-topics
- If you only want to establish ROS2 to ROS1 bridge, you can use
bridge-all-2to1-topics
$ ros2 run ros1_bridge dynamic_bridge --bridge-all-2to1-topics
Parameter_bridge
The parameter_bridge can bridge only selected topics and services by using a YAML file.
For example, only bridge a topic called chatter.
How to use parameter_bridge can refer to parameter_bridge
Parametrizing Quality of Service
It also can define different Quality of Service(QoS) settings per topic, for instructions on how to do this, please refer to parametrizing-quality-of-service
Supported ROS 2 <=> ROS 1 message and service type
You can list all ros1_bridge supported type by using following command.
$ ros2 run ros1_bridge dynamic_bridge --print-pairs

Issue
However, using the ROS 1 Bridge can also bring some issues. First, since the message formats of ROS 1 and ROS 2 are different, the ROS 1 Bridge needs to perform message format conversion, which can result in latency and CPU usage. Second, message drops may occur due to the message transmission required by the ROS 1 Bridge.
Therefore, when using the ROS 1 Bridge to port ROS 1 to ROS 2, these issues should be taken into account, and optimization and debugging should be carried out according to specific situations to ensure system stability and performance.
- Latency and cpu usage
- During the ROSCon'22 speech, it was mentioned that using ros1-bridge can cause issues such as high latency and CPU usage. The following chart compares the differences between using and not using ros1-bridge, which clearly shows the disparity. If interested, please visit the website to watch the speech.

- TF and pointcloud delay
- Some users have also mentioned in Github Issues that there are latency issues when using TF or large datasets (such as point clouds).
- TF and pointcloud delay
In conclusion, the ROS1 bridge provides a convenient way to achieve data communication between ROS1 and ROS2. However, it is not recommended to use the bridge in high-frequency or large dataset scenarios. In such cases, it is recommended to directly port the ROS1 code to the ROS2 code.
