Revision history [back]

That's because roscd takes you to the share folder of a package, but the binaries live somewhere else.

> ls /opt/ros/melodic/lib/robot_localization
ekf_localization_node  robot_localization_listener_node
navsat_transform_node  ukf_localization_node

Replace melodic with the name of your distro if you are on a different one.

Of course, you don't actually need to know where they are if you just want to run them. rosrun robot_localization ekf_localization_node will know where to find the binary and run it.
