From the images it looks like it's planning through holes in the walls that lead to unknown space. If that's not what you want, you could disallow moving through unknown cells (there's a parameter for this somewhere; note: I've had problems with voxel and unknown cells before, I'd recommend using a plain 2d costmap).

You have to subscribe to both .../costmap and .../costmap_updates.

Yes, it continually updates, although I've experienced problems in some circumstances (not sure exactly which, it was a while ago).

Actually, in rospy all parameter accesses are cached automatically. Not sure about the errors though. Correction: ignore my message, there is some code for caching but it's disabled (eg. https://github.com/ros/ros_comm/blob/hydro-devel/clients/rospy/src/rospy/msproxy.py line 114).

I've submitted a really simple script implementing what Stefan suggested.

I haven't tried it, but with a version of ROS newer than August 2012 it should be possible to do something like the following:

import logging
class Filter(logging.Filter):
    def filter(self, record):
        return 'State machine transitioning' not in record.msg
logging.getLogger('rosout').addFilter(MyFilter())

Maybe you need to explicitly declare the output key in the State Machine?

Like this:

smach.StateMachine.add('FOO',
                  ServiceState('/service',
                                myService,
                                response_cb=foo_response_cb,
                                output_keys=['foo_var_out']),
                  remapping={'foo_var_out':'sm_var'},
                  transitions={'succeeded':'succeeded'},
                  output_keys=['sm_var'])

Maybe you need to explicitly declare the output key in the State Machine?

For example:

smach.StateMachine.add('FOO',
                  ServiceState('/service',
                                myService,
                                response_cb=foo_response_cb,
                                output_keys=['foo_var_out']),
                  remapping={'foo_var_out':'sm_var'},
                  transitions={'succeeded':'succeeded'},
                  output_keys=['sm_var'])

Hi,

I've installed ROS on Ubuntu Oneiric (11.10), using the Natty repository and manually installing needed Natty packages (eg. libglut3).

ROS itself and Gazebo (the stuff in the tutorial) work fine, however I can't get gazebo_plugins to build.

Here's the build log: http://paste.debian.net/plain/150875

The visualization_common stack is installed (there's an ogre/ROS_NOBUILD file in there, I suppose that's normal?).

I've tried installing the OGRE packages from Natty, but that didn't help.

$ dpkg -l | grep ogre
ii  libogre-dev                                                 1.6.4.dfsg1-1ubuntu1                    Object-oriented Graphics Rendering Engine (development files)
ii  libogremain-1.6.4                                           1.6.4.dfsg1-1ubuntu1                    Object-oriented Graphics Rendering Engine (libraries)

Any ideas?
