Hello @bayodesegun, I cant find this @Your First Robot with ROS@ course and the previous “build your first robot with ros…” has deprecated in bracket. Am I wasting my time with the deprecated course? I am currently facing issues with setting up my camera using instructions from the course.

I get this error at the end of my catkin_make of raspicam_node:

make[1]: *** [CMakeFiles/Makefile2:443: raspicam_node/CMakeFiles/raspicam_node.dir/all] Error 2
make: *** [Makefile:141: all] Error 2
Invoking “make -j4 -l4” failed

Also, when I run roslaunch raspicam_node camera_module_v2_640x480_30fps.launch, I get this error and then it closes:

ERROR: cannot launch node of type [raspicam_node/raspicam_node]: Cannot locate node of type [raspicam_node] in package [raspicam_node]. Make sure file exists in package path and permission is set to executable (chmod +x)

Please help.

The course is deprecated where it is related to building an actual robot because some of the parts may not be available anymore, but the simulation should work.

Please paste the complete output of the error message that happens when you catkin_make. If the build was not successful, roslaunch will surely fail.
