Hi, Josh. Thank you very much for the immediate responce. Your advice helps me a lot. Keisuke Josh Faust wrote: The message IDL does not currently support map/dict types, no.

Is there a way to publish/subscribe following message types in ROS? "std::map" more than double vector like "std::vector>" More precisely, I would like to send std::map> type message. Is it possible? Any information is welcome. Thanks in advance.
