Hi there,

Does somebody know from where to get the package "knowrob_map_data" and "knowrob_map_tools" for kinetic?

I installed KnowRob following the instructions from the website, but I get an error when owl_parsing the package (package not found).

?- owl_parse('package://knowrob_map_data/owl/ccrl2_semantic_map.owl').

I inspected the KnowRob folder and the package "knowrob_map_data" was indeed missing.

Browsing for the package in ROS-wiki, the package appears under knowrob (indigo, melodic, older), but once in the repository it is missing.


OS: Ubuntu 16.04, ROS Kinetic

HI , It's seems that the tutorials is not up to date since "knowrob_map_data" doesn't exist anymor in KINETIC (Look here).

This package has been replaced by "Knowrob_maps", so you just have to replace this :


by that :


Good Luck !

Thx Jayess. That works fine.

Now I'm dealing with some log4j problems. It seems there are some configuration problems. Any ideas?

log4j:WARN No appenders could be found for logger (org.ros.internal.node.client.Registrar). log4j:WARN Please initialize the log4j system properly.

Hi, still i am getting package not found error after i replaced the package "Knowrob_maps" instead of "knowrob_map_data". register_ros_package(knowrob_maps). owl_parse('package://knowrob_maps/owl/ccrl2_semantic_map.owl'). I will really appreciate some help here.

Hi @gayathari Could you overcome this problem?

Just to add: I am getting this error message too, but this is because there is no ccrl2_semantic_map.owl file in knowrob_maps. I believe this file has been removed, so this part of the knowrob basics tutorial cannot be followed using the referenced file.
