Network Bridge

CI

Network Bridge is a lightweight ROS2 node designed for robust communication between robotic systems over arbitrary network protocols. Supporting UDP and TCP protocols out of the box, this packages seamlessly bridges ROS2 topics across networks, facilitating effective remote communications between a base station and robotic systems, or between multiple robotic systems.

Installation

Installation via apt

Install with:

sudo apt install ros-<distro>-network-bridge

Building from Source

Simply clone the repository into your ROS2 workspace and build with colcon build.

Usage

Demo

TCP

ros2 launch network_bridge tcp.launch.py

ros2 topic pub /tcp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /tcp2/MyDefaultTopic

UDP

ros2 launch network_bridge udp.launch.py

ros2 topic pub /udp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /udp2/MyDefaultTopic

Configuration

Simply setup the network interface parameters and list your desired topics to get started. If you are using UDP over cellular data, it is recommended to setup a VPN to facilitate connection. Also, please note that no encryption occurs within this package. Currently, if you would like encryption, you must use a VPN.

See config/Udp1.yaml for a description of all parameters, as well as the TCP example configuration files.

Minimal Example

The following configuration examples demonstrate a robot sending a message on /gps/fix over UDP to a basestation that will then re-publish the message. This works seamlessly on all message types, so long as they are built and sourced on both ends of the transmission.

Robot

/udp_sender:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.2"
      receive_port: 5001
      remote_address: "192.168.1.3"
      send_port: 5000

    topics:
      - "/gps/fix"

Base Station

/udp_receiver:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.3"
      receive_port: 5000
      remote_address: "192.168.1.2"
      send_port: 5001

Special case: TF

The TF topic /tf or /tf_static are handled as a special cases. The subscriber side will listen to all TF messages, accumulate them (similarly to a TF buffer) and send all of them at the specified rate. The behavior can be disabled or forced using the is_tf configuration.

If some TFs need to be excluded or if the list of TFs to include is finite, one can use the include and exclude regex parameters. A transform is matched (hence excluded or included) if either the frame_id or child_frame_id are matching a pattern.

/udp_sender:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.2"
      receive_port: 5001
      remote_address: "192.168.1.3"
      send_port: 5000

    topics:
      - "/prefix/tf"
      - "/tf_static"

    /prefix/tf:
      - is_tf: True
      - is_static_tf: False
      - rate: 10.

    /tf_static:
      - rate: 1.0
      - is_static_tf: True
      - exclude: ["standoff.*", "spacer.*", ".*wheel_link", ".*cliff.*"]

Choice of protocol

  • UDP: Use UDP for low-latency, high-throughput communications, where occasional data loss is tolerable. Ideal for real-time telemetry data like sensor streams.
  • TCP: Opt for TCP when data integrity and reliability are critical. This ensures that control commands and state transitions are reliably delivered, though with potentially higher latency.

Network protocols are implemented as pluginlib plugins, allowing the creation of arbitrary interfaces using the abstract class include/network_interfaces/network_interface_base.hpp. Any interface that can send and receive bytes could theoretically be implemented, including protocols that go beyond point-to-point communication, such as ZMQ. Please consider opening a pull request if you implement a new network interface.

Package Description

Allows for arbitrary network links (UDP, TCP, etc) to bridge ROS2 messages

Network Bridge

CI

Network Bridge is a lightweight ROS2 node designed for robust communication between robotic systems over arbitrary network protocols. Supporting UDP and TCP protocols out of the box, this packages seamlessly bridges ROS2 topics across networks, facilitating effective remote communications between a base station and robotic systems, or between multiple robotic systems.

Installation

Installation via apt

Install with:

sudo apt install ros-<distro>-network-bridge

Building from Source

Simply clone the repository into your ROS2 workspace and build with colcon build.

Usage

Demo

TCP

ros2 launch network_bridge tcp.launch.py

ros2 topic pub /tcp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /tcp2/MyDefaultTopic

UDP

ros2 launch network_bridge udp.launch.py

ros2 topic pub /udp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /udp2/MyDefaultTopic

Configuration

Simply setup the network interface parameters and list your desired topics to get started. If you are using UDP over cellular data, it is recommended to setup a VPN to facilitate connection. Also, please note that no encryption occurs within this package. Currently, if you would like encryption, you must use a VPN.

See config/Udp1.yaml for a description of all parameters, as well as the TCP example configuration files.

Minimal Example

The following configuration examples demonstrate a robot sending a message on /gps/fix over UDP to a basestation that will then re-publish the message. This works seamlessly on all message types, so long as they are built and sourced on both ends of the transmission.

Robot

/udp_sender:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.2"
      receive_port: 5001
      remote_address: "192.168.1.3"
      send_port: 5000

    topics:
      - "/gps/fix"

Base Station

/udp_receiver:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.3"
      receive_port: 5000
      remote_address: "192.168.1.2"
      send_port: 5001

Special case: TF

The TF topic /tf or /tf_static are handled as a special cases. The subscriber side will listen to all TF messages, accumulate them (similarly to a TF buffer) and send all of them at the specified rate. The behavior can be disabled or forced using the is_tf configuration.

If some TFs need to be excluded or if the list of TFs to include is finite, one can use the include and exclude regex parameters. A transform is matched (hence excluded or included) if either the frame_id or child_frame_id are matching a pattern.

/udp_sender:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.2"
      receive_port: 5001
      remote_address: "192.168.1.3"
      send_port: 5000

    topics:
      - "/prefix/tf"
      - "/tf_static"

    /prefix/tf:
      - is_tf: True
      - is_static_tf: False
      - rate: 10.

    /tf_static:
      - rate: 1.0
      - is_static_tf: True
      - exclude: ["standoff.*", "spacer.*", ".*wheel_link", ".*cliff.*"]

Choice of protocol

  • UDP: Use UDP for low-latency, high-throughput communications, where occasional data loss is tolerable. Ideal for real-time telemetry data like sensor streams.
  • TCP: Opt for TCP when data integrity and reliability are critical. This ensures that control commands and state transitions are reliably delivered, though with potentially higher latency.

Network protocols are implemented as pluginlib plugins, allowing the creation of arbitrary interfaces using the abstract class include/network_interfaces/network_interface_base.hpp. Any interface that can send and receive bytes could theoretically be implemented, including protocols that go beyond point-to-point communication, such as ZMQ. Please consider opening a pull request if you implement a new network interface.

Network Bridge

CI

Network Bridge is a lightweight ROS2 node designed for robust communication between robotic systems over arbitrary network protocols. Supporting UDP and TCP protocols out of the box, this packages seamlessly bridges ROS2 topics across networks, facilitating effective remote communications between a base station and robotic systems, or between multiple robotic systems.

Installation

Installation via apt

Install with:

sudo apt install ros-<distro>-network-bridge

Building from Source

Simply clone the repository into your ROS2 workspace and build with colcon build.

Usage

Demo

TCP

ros2 launch network_bridge tcp.launch.py

ros2 topic pub /tcp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /tcp2/MyDefaultTopic

UDP

ros2 launch network_bridge udp.launch.py

ros2 topic pub /udp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /udp2/MyDefaultTopic

Configuration

Simply setup the network interface parameters and list your desired topics to get started. If you are using UDP over cellular data, it is recommended to setup a VPN to facilitate connection. Also, please note that no encryption occurs within this package. Currently, if you would like encryption, you must use a VPN.

See config/Udp1.yaml for a description of all parameters, as well as the TCP example configuration files.

Minimal Example

The following configuration examples demonstrate a robot sending a message on /gps/fix over UDP to a basestation that will then re-publish the message. This works seamlessly on all message types, so long as they are built and sourced on both ends of the transmission.

Robot

/udp_sender:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.2"
      receive_port: 5001
      remote_address: "192.168.1.3"
      send_port: 5000

    topics:
      - "/gps/fix"

Base Station

/udp_receiver:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.3"
      receive_port: 5000
      remote_address: "192.168.1.2"
      send_port: 5001

Special case: TF

The TF topic /tf or /tf_static are handled as a special cases. The subscriber side will listen to all TF messages, accumulate them (similarly to a TF buffer) and send all of them at the specified rate. The behavior can be disabled or forced using the is_tf configuration.

If some TFs need to be excluded or if the list of TFs to include is finite, one can use the include and exclude regex parameters. A transform is matched (hence excluded or included) if either the frame_id or child_frame_id are matching a pattern.

/udp_sender:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.2"
      receive_port: 5001
      remote_address: "192.168.1.3"
      send_port: 5000

    topics:
      - "/prefix/tf"
      - "/tf_static"

    /prefix/tf:
      - is_tf: True
      - is_static_tf: False
      - rate: 10.

    /tf_static:
      - rate: 1.0
      - is_static_tf: True
      - exclude: ["standoff.*", "spacer.*", ".*wheel_link", ".*cliff.*"]

  • UDP: Use UDP for low-latency, high-throughput communications, where occasional data loss is tolerable. Ideal for real-time telemetry data like sensor streams.

Choice of protocol

Network protocols are implemented as pluginlib plugins, allowing the creation of arbitrary interfaces using the abstract class include/network_interfaces/network_interface_base.hpp. Any interface that can send and receive bytes could theoretically be implemented, including protocols that go beyond point-to-point communication, such as ZMQ.

Network Bridge

CI

Network Bridge is a lightweight ROS2 node designed for robust communication between robotic systems over arbitrary network protocols. Supporting UDP and TCP protocols out of the box, this packages seamlessly bridges ROS2 topics across networks, facilitating effective remote communications between a base station and robotic systems, or between multiple robotic systems.

Installation

Installation via apt

Install with:

sudo apt install ros-<distro>-network-bridge

Building from Source

Simply clone the repository into your ROS2 workspace and build with colcon build.

Usage

Demo

TCP

ros2 launch network_bridge tcp.launch.py

ros2 topic pub /tcp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /tcp2/MyDefaultTopic

UDP

ros2 launch network_bridge udp.launch.py

ros2 topic pub /udp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /udp2/MyDefaultTopic

Configuration

Simply setup the network interface parameters and list your desired topics to get started. If you are using UDP over cellular data, it is recommended to setup a VPN to facilitate connection. Also, please note that no encryption occurs within this package. Currently, if you would like encryption, you must use a VPN.

See config/Udp1.yaml for a description of all parameters, as well as the TCP example configuration files.

Minimal Example

The following configuration examples demonstrate a robot sending a message on /gps/fix over UDP to a basestation that will then re-publish the message. This works seamlessly on all message types, so long as they are built and sourced on both ends of the transmission.

Network Bridge

CI

Network Bridge is a lightweight ROS2 node designed for robust communication between robotic systems over arbitrary network protocols. Supporting UDP and TCP protocols out of the box, this packages seamlessly bridges ROS2 topics across networks, facilitating effective remote communications between a base station and robotic systems, or between multiple robotic systems.

Installation

Installation via apt

Install with:

sudo apt install ros-<distro>-network-bridge

Building from Source

Simply clone the repository into your ROS2 workspace and build with colcon build.

Usage

Demo

TCP

ros2 launch network_bridge tcp.launch.py

ros2 topic pub /tcp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /tcp2/MyDefaultTopic

UDP

ros2 launch network_bridge udp.launch.py

ros2 topic pub /udp1/MyDefaultTopic std_msgs/msg/String "data: 'Hello World'"

ros2 topic echo /udp2/MyDefaultTopic

Configuration

Simply setup the network interface parameters and list your desired topics to get started. If you are using UDP over cellular data, it is recommended to setup a VPN to facilitate connection. Also, please note that no encryption occurs within this package. Currently, if you would like encryption, you must use a VPN.

See config/Udp1.yaml for a description of all parameters, as well as the TCP example configuration files.

Minimal Example

The following configuration examples demonstrate a robot sending a message on /gps/fix over UDP to a basestation that will then re-publish the message. This works seamlessly on all message types, so long as they are built and sourced on both ends of the transmission.

Robot

/udp_sender:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.2"
      receive_port: 5001
      remote_address: "192.168.1.3"
      send_port: 5000

    topics:
      - "/gps/fix"

Base Station

/udp_receiver:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.3"
      receive_port: 5000
      remote_address: "192.168.1.2"
      send_port: 5001

Special case: TF

The TF topic /tf or /tf_static are handled as a special cases. The subscriber side will listen to all TF messages, accumulate them (similarly to a TF buffer) and send all of them at the specified rate. The behavior can be disabled or forced using the is_tf configuration.

If some TFs need to be excluded or if the list of TFs to include is finite, one can use the include and exclude regex parameters. A transform is matched (hence excluded or included) if either the frame_id or child_frame_id are matching a pattern.

/udp_sender:
  ros__parameters:
    UdpInterface:
      local_address: "192.168.1.2"
      receive_port: 5001
      remote_address: "192.168.1.3"
      send_port: 5000

    topics:
      - "/prefix/tf"
      - "/tf_static"

    /prefix/tf:
      - is_tf: True
      - is_static_tf: False
      - rate: 10.

    /tf_static:
      - rate: 1.0
      - is_static_tf: True
      - exclude: ["standoff.*", "spacer.*", ".*wheel_link", ".*cliff.*"]

Choice of protocol

  • UDP: Use UDP for low-latency, high-throughput communications, where occasional data loss is tolerable. Ideal for real-time telemetry data like sensor streams.
  • TCP: Opt for TCP when data integrity and reliability are critical. This ensures that control commands and state transitions are reliably delivered, though with potentially higher latency.

Network protocols are implemented as pluginlib plugins, allowing the creation of arbitrary interfaces using the abstract class include/network_interfaces/network_interface_base.hpp. Any interface that can send and receive bytes could theoretically be implemented, including protocols that go beyond point-to-point communication, such as ZMQ. Please consider opening a pull request if you implement a new network interface.
