Possible Mistake on Unit 1 Notes

Course Support TF ROS 101
1

Hello, just wanted to inform that at the end of Exercise 2.1 there’s this comment: As you can see, all three frames corresponding to the 3D turtle, the iRobot, and the Coke_can now appear in the TF Tree.

This is incorrect since by this time, we have just made the tf broadcast of turtle1 and turtle2 frames. So we can only see world, turtle1 and turtle2 (turtle1 being above world, since it seems the turtle is on the origin of Gazebo). Coke can seems to be the next exercise.

Just wanted to point this out if you want to correct it.

Best regards,
ÁngelLoGa
