Cannot read the dark blue text on a black background. Can you please change for future tutorials.

[@RoboticsBackEnd]

Thanks for the feedback - yes that's something I detected too late! Will change that in the next tutorials :)

Thank you from the bottom of my heart for these tutorials! I am trying to create a drone, and I had problems with performances. As I am doing everything with my raspberry pi 3b+, I got a build time that is 10 times bigger than yours.. Is there any way to work with a less powerful device with the same performances of a laptop? Thanks again for your work!

[@RoboticsBackEnd]

Thanks for the kind words! Unfortunately it takes a much longer time to compile on Raspberry Pi, and I haven't really found any workaround for that. One idea is to try cross-compilation, but trying that is probably a direct path to insanity, so... gotta have to wait.

Hallo Eduard, thank you for this good crashcourse. I wuld like o make you Udemy course. Include this course selfnavigatin with an lidar scanner? Best reards Samy

[@RoboticsBackEnd]

Thanks for the suggestion Samy, I might add content about Lidar integration in the future.

[@danieleaffinita3614]

I faced this error. --- stderr: my_robot_controller listing git files failed - pretending there aren't any --- Any idea?

hello...I encountered this error>>>>>ERROR:colcon:colcon build: Duplicate package names not supported

[@RoboticsBackEnd]

Make sure that: 1. you are only using (sourcing) one workspace at a time in your environment, and 2. remove everything in install/ and build/, and do "colcon build" again.

[@karthikrajgopal8310]

I installed 58.2.0 setuptools but still getting the error.

[@nanibabughantasala2949]

Sir can you update your udemy course like do it with ros humble

[@RoboticsBackEnd]

Even better, I will update it to ROS Jazzy after it's released :)

[@manarkassim447]

Hi, thanks for this helpful video! I want to ask you regarding the build colcon step, it failed. An error is showing up on my terminal: ’’import distutils.command.bdist_wininst as ModuleNotFoundError: No module named 'distutils.command.bdist_wininst'’’’ Is there any way to solve this error ? Thanks for your help!

[@jereminuer5049]

I had the same error. Have you had any luck fixing it?

[@gobindachandrasarker4523]

Hi. even after downgrading setuptools, the deprecation error still showing. How to fix that?

[@RoboticsBackEnd]

if it's just a warning and everything works fine, you can ignore that log!

Hi When I use the command "sudo snap install code --classic," I get the following snap "code" is not available on stable for this architecture (arm64) but exists on other architectures (amd64) error . What is the solution?

[@RoboticsBackEnd]

"standard" laptops and computer have an AMD architecture. If you're using something like a Raspberry Pi, phone, tablet, embedded devices, etc, chances are that the architecture is ARM. In this case I'm not sure you can really do anything :/ maybe try with another computer

[@INNOVA8R]

I am facing the same issue and i am using MAC can you help me out

[@RoboticsBackEnd]

That's a bit hard to debug with just this error, but I would maybe suggest that you try uninstalling and reinstalling ROS2 (+ do the configuration). Seems that there could be some permissions issues due to a wrong configuration.

[@leafteaneko]

This looks like the same error I was encountering, I solved it by giving read/write permission of the workspace to all users. Keep in my mind this might not be a good idea from a security standpoint, I was using a VM so I dont really mind. 1. cd 2. sudo chmod 777 -R .
