Open Robotics has a survey asking for your feedback. Fill it in to enter a prize draw!

Open Robotics works to support the development, distribution, and adoption of open-source software for use in robotics research, education, and product development. As an organisation and as a movement, we know a lot about the software, tools and standards that we build, but we do not know enough about the people who use them in their work, in their hobbies, and in their studies.

What motivates people to use the Open Robotics Suite (ROS, ros-controls, Space ROS, Gazebo, Open-RMF, and the infrastructure that supports them), in whole or in part? What motivates companies to make their products depend on our software? What features are actually relied upon every day, and which are no longer necessary? Or, conversely, what motivates someone to not use the Open Robotics Suite? To begin answering these questions, we are starting a new annual survey of everyone who is or could be using our software.

We are asking anyone and everyone who is in robotics, in any way, to answer this survey. Even if you do not use any Open Robotics software, or you think that ROS is not suitable for your work, or you’ve only just started learning Gazebo, or you tried and have abandoned ROS, we still want to hear from you. If you’ve never used ROS, Gazebo, or any of our other software, we want to hear from you!

Achieving our mission requires knowing who we are or should be building software for, no matter who they are or where they use it. This survey is how we get to know our community better.

You can fill in the survey by following this link: https://go.openrobotics.org/orsurvey26

paraphrasing one attendee: I didn't know that I wanted this

Any linux wizards know why when my sound sources go to background and CPU is under heavy load the audio crackles?

apps tested: minecraft, vlc(flatpak), spotify(flatpak), other fltapaks
crackles on both bluetooth and minijack headphones,
disabling microphone, easyeffects, gpu screen recorder ( gsr-default_output) didn't help

I use blender to put the load on CPU but it also happens when compiling or gaming

I have increased stuff in cat /etc/pipewire/pipewire.conf

I know to little to dig into the scheduler stuff. systemctl status rtkit-daemon prints about pipewire sucess at priority 20.

I would like to know more about theoretical side of robotics as I so far had only the practical experience.

I also could be interested in lectures on YT.
