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!
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
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.
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?
"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
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!
Hi Sir Thank You for these awesome videos and have suggested them to many of my friends But got stuck in proceeding furthur Got this error while command @7.38 colcon build Traceback (most recent call last): File "/usr/bin/colcon", line 11, in load_entry_point('colcon-core==0.10.0', 'console_scripts', 'colcon')() File "/usr/lib/python3/dist-packages/colcon_core/command.py", line 118, in main return _main(command_name=command_name, argv=argv) File "/usr/lib/python3/dist-packages/colcon_core/command.py", line 185, in _main create_log_path(args.verb_name) File "/usr/lib/python3/dist-packages/colcon_core/location.py", line 186, in create_log_path os.makedirs(str(path)) File "/usr/lib/python3.10/os.py", line 215, in makedirs makedirs(head, exist_ok=exist_ok) File "/usr/lib/python3.10/os.py", line 225, in makedirs mkdir(name, mode) PermissionError: [Errno 13] Permission denied: 'log' Please help me to rectify Thank You in Advance
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.
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 .
