Do anyone have any idea what’s going on?
The simulation is on my pc running Ubuntu 16.04 and ROS Kinetic.
Gazebo starts perfectly but without Husky ( I meant to say Gazebo only launches the empty world ).
When I source the terminal with /opt/ros/kinetic/setup.bash and try to launch the file husky_playpen.launch, everything works perfectly fine.
But when I source the terminal with /catkin_ws/devel and try to launch the file husky_playpen.launch, the program gives below error.
When I tried a different code (other than the already existing binary package) from “https://github.com/nickcharron/waypoint_nav” github repo, compiled it and tried to run it from source, I got the error.
Thanks in advance.
