I want to call the costmap_clear service of a rosndk native move_base node from ROSjava. I found an example in the Rosjava docu. But i cant see the service when i start move_base. Its not listed in rosnode info and not in rosservice list. I tried starting the move_base node on my pc but still no services.... Do i have to somehow start the service before i can call it? Thanks in advance

EDIT: only 2 services are listed under move_base: /move_base/get_loggers /move_base/set_logger_level

Hi @manster2209,

If you start the node but you don't see the service listed in move_base, it's likely that something went wrong during the initialization.

move_base should provide the service server for that service; if that part doesn't start you won't be able to call it using rosjava nor anything else.

Take a look at the documentation for move_base : . Then take a look at the output of your program. Do you see any errors? For the current kinetic branch, the code starting the service server is here: . There are a bunch of conditions that may cause the node to exit before getting there, so I'd start looking at that.

Once you see the service listed, calling it using Rosjava is a separate problem.

Well the thing is otherwise move_base works as it is supposed to. I can drive my robot around and all. I just don't see the services... no errors

Which version of move_base are you using? the cross compiled one in ?

I just checked and the version that is being cross compiled is move_base 1.12.3. The source code looks similar at that place: so the service should be available. If you don't see it, you should see some error log
