this is one of the example using pybind11 with ros package: https://github.com/IntelRealSense/librealsense/tree/master/w

try setting the planner_frequency to 0 in move_base dynamic reconfigure. This way move base will not feed plan again and

Try following the example launch and use yaml file given in the tutorial, by replacing with your desired angles. If you

one thing, static_layer does not update according to laser_scan but from static maps.

the scan is LaserScan msg which has the header/frame_id to specify the frame.

sorry for confusion. I mean there should be one under catkin_ws/src that is created by catkin_init_workspace. Other one

In the structure of directory posted in question, the CMakeLists.txt of package is missing, but I'm assuming it's there.

You need to specify the modules to import in __init__.py. Check if you have something like from . import MAPEopcode in y

Hi Alex! I tried with gazebo and I was able to get two pointclouds, assembled every 1 second, using the approach above.

and 2. Write your own version of periodic_snapshotter that gets point_cloud from both and adds them.

Launch 2 instances of laser_assembler as described in 4.3 of laser_assembler wiki. (group them under namespaces to sepa

This doesn't seems to be the case. Publishing just the plan from standard global planner is a list of all the poses, and

Are you running this from rosrun or roslaunch?

Make sure rostful is installed on your system, it seems it is not. From the rostful repos, it appears it's not officiall

You would need to write setup.py and include catkin_python_setup() in CMakeLists as described in Section 1.2 here. This

It would help to publish the plan also so you can visualise in rviz if it is what you expect.

This is because script say.py (must be written to be a standalone python script and hence) accepts sysargs. When say.py

I replicated just the bash script and on it runs the roscore. Is there I am missing?

If it doesn't hurt you, you can also use roslaunch API instead of subprocess. I guess the API isn't stable and don't kno

That depends on the node publishing these topics. Assuming both the topics are published together/with same rate, then m

As I see, you would need to launch two instances laser_scan_assember for each and then add the two resulting point cloud

I think it would be technically incorrect to say "call subscibers". The callbacks are called whenever a message is recei

As stated in description, "The TimeSequencer filter guarantees that messages will be called in temporal order according

I suspect that this problem is due to TimeSequencer working with topics having time stamps. which means if you replace s

You might need to implement a bridge between these two classes using something like zeromq or http requests. If the two

The topic names are kind of address names or lookup so shouldn't affect on vision processing.

what do you mean using python? Is there a python node launched in the xxx.launch? or you are reading this launch file in

It should be possible. I don't know about how to do using the core Marker msgs but I have done something similar using h

One thing I can notice is tfListener_.waitForTransform is missing, not sure if it's related though.

The reason it cannot find your module is that it is not in your $PYTHONPATH. The standard way of solving this would be t

This problem is solved by doing exactly what it told you: "Please create a subscriber to the marker" When you do rosrun
