ROS Answers SE migration: node not found

Question

Dear Ros-users, I downloaded package youbot_navigation for ros-hydro. I compiled it with catkin_make without error but when I try to run the lowpass_filter get ERROR: cannot launch node of type [youbot_navigation_common/lowpass_filter]: can't locate node [lowpass_filter] in package [youbot_navigation_common] even if the node is correctly compiled with catkin_make:
[ 15%] Built target lowpass_filter

the launch file is: roslaunch youbot_navigation_local move_base_local.launch

The complete output of catkin_make is:

raffaele@raffaele:~/ros/hydro_node/catkin_ws$ catkin_make Base path: /home/raffaele/ros/hydro_node/catkin_ws Source space: /home/raffaele/ros/hydro_node/catkin_ws/src Build space: /home/raffaele/ros/hydro_node/catkin_ws/build Devel space: /home/raffaele/ros/hydro_node/catkin_ws/devel Install space: /home/raffaele/ros/hydro_node/catkin_ws/install

Thank you!

Hi Rahndall, can you edit your post to give us the complete output of catkin_make? And which launch command are you using?

Answer 1

HI

try

# In your catkin workspace
$ cd ~/catkin_ws
$ source ./devel/setup.bash

and then run your program.
