ros_comm_tools

This ROS stack provides a collection of communication tools that allow for advanced topic interactions and other functionalities within the ROS ecosystem.

Current Structure

The ros_comm_tools stack currently comprises the following package(s):

• add_topic_tools:
  • Nodes:
    • Triggered Publisher: Subscribe to a topic and republish its content to another topic upon a user-defined trigger, such as pressing a button.

More packages and nodes will be added to this stack in the future to further enhance its capabilities.
