Assignment 7: More Launch File Practice 2¶
According to what you've learned in Lesson 5: Launch Files and Lesson 7: Topic Remapping, create a launch file that can:
- launch four turtlesim_node
- make turtlesim3 mimic turtlesim1; turtlesim4 mimic turtlesim2.
In a new terminal, run:
ros2 topic pub -r 1 /turtlesim1/turtle1/cmd_vel geometry_msgs/msg/Twist "{linear: {x: 2.0, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: -1.8}}"
In a new terminal, run:
ros2 topic pub -r 1 /turtlesim2/turtle1/cmd_vel geometry_msgs/msg/Twist "{linear: {x: -4.0, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: -1.8}}"
Run the rqt tool:
