I am running rbx1 with ROS hydro. This is the nodes I am running: roslaunch rbx1_nav fake_move_base_map_with_obstacles.launch. It seems to work ok, but I am getting an error:

brent@brent:~$ roslaunch rbx1_nav fake_move_base_map_with_obstacles.launch

Is there a parameter, or parameters that I need to clear?

Thank you, Brent

It looks like you have another node running (/leaf_base), which is publishing Odometry and the transform for base_link, but the transform itself contains invalid data. X and Y and NaN (Not A Number), and so is the quaternion which represents rotation.

You should look at your leaf_base node and try to figure out why it's publishing a bad transform.
