  • Communicate to other nodes
  • Example
    • $ rosrun [package_name] [node_name]

       

Topics

  • Bus nodes exchange messages over
  • Message type
  • Fire and forget
  • Example
    • $ rostopic list
    • $ rostopic echo /[topic_name]

Pub/Sub

Actions

  • Goal - Intent for robot
    • Move to specific location by passing params
  • Feedback - Incremental progress of a goal
    • Current pose on path, time left
  • Result - Similar to feedback but sent once
