In what context are you running this?
Do you have something on the robot/setsup that is generating an odom -> base_link tf?
@JackB i use it to create a Map using Gmapping in ROS Simulation
Answer the second questions please
@JackB no i don't have
Well you need to find something to generate that transform. The lack of that tf is what the error is I think
@JackB how i can generate tf
