Chapter 5. TF Quiz 2. How to move two turtlebot

Course Support TF ROS 101

Hello,

I think my quiz answer is correct as below. But, I am not sure how to move two turtlebot at the same time. Do I need to send command manually? What I did is that I used rostopic pub command, and sent cmd_vel topic to robot1. But, the robot2 does not follow the robot1.

Thank you for your support.

Hi,
Once the TF trees of both the bots are linked you can move both of individually and you should be able to visualize them both in rviz at the same time.

To test if your quiz solution is successful, you can use rostopic pub twice in two different terminals.
