This doesn't directly answer your question, but in the past I have made my CUDA-specific code a custom external C++ libr

It's certainly better. There's no "acceptable" because the Nav stack can compensate for poor odometry with more/better f

Specifically re: the RPi, it's a quad core, so your GUI thread should only use 25% of the CPU worst case, so your other

This will very much depend on how "fancy" the Qt code is, as to whether it will impact anything at all. If it's just but

Well, in that case it certainly could slow down the system. Which of course begs the question, why do you need it to be

By micro-controller, I assume you mean processor? It would probably help to say what hardware you are running, e.g. a no

My guess is that you should have sufficient encoder resolution for much better accuracy than you are seeing. I've gotten

This is asking a lot of different things. As to the visualizing of the poses, rviz is the best thing to use for that. An

The short answer is you want to use the ROS nav stack. As @gvdhoorn mentioned this is a broad topic, and is covered else

I'm glad it works!

I'm glad it works! If this fixed your original problem you can mark this answer as correct.

Okay. Probably better to use job control, or some other process monitor then, that way you can keep an eye on things and

I seem to recall that making an array solved the whole redraw/update problem. I had originally tried to set a short life

Couldn't image_saver work on a playing bag file? I guess I don't understand the difference between image_saver and extra

I think this is a perfectly fine way of visualizing a skeleton in RVIZ. I would recommend adding them all into one Marke

Have you tried image_saver? It includes an encoding parameter that could allow you to explicitly set it as RGB or BGR.

You should just be able to concatenate strings by adding them: with open(rospack.get_path('<package_name>')+'/csv

I'm not sure if this would fit your needs, but you could possibly make your CUDA specific code a custom external library

If you really are just recreating the functionality of roslaunch though, I would recommend using that instead, as it pro

Also, as to whether using a script like this is a good idea, I've never seen anyone do it but I don't see why it wouldn'

I'm not sure how it would affect the stability of your node, but roslaunch does spawn each node into its own process, an
