Turtlesim Comms: List Topics

Listing All Topics

In a similar fashion, we are able to query the ROS Master for a list of all topics. To do so, we use the command rostopic list .

/rosout_agg
Aggregated feed of messages published to /rosout.
/turtle1/cmd_vel
Topic upon which velocity commands are sent/received. Publishing a velocity message to this topic will command turtle1 to move.
/turtle1/color_sensor
Each turtle in turtlesim is equipped with a color sensor, and readings from the sensor are published to this topic.
/turtle1/pose
The position and orientation of turtle1 are published to this topic.
