This course is very well structured and laid out in way that probably anyone can follow (as long as you do not skip steps). Even if you've never used Python before but have some experience with programming languages it's very straightforward to follow.

Nice I like how python auto builds but cmake tools extention in vs code does the same thing with c++ or am I getting ahead of myself? Your next video might cover that just saying because I hear that's why some people choose python over c++.

hey man, i love your course, im currently learning about drone programming, can you make a course about drone autopilot programming with ros2? im using px4 and i noticed there's a lack of tutorial from beginners on this topic. I will buy it if u decides to make one.

thanks for the feedback! Currently I have no plans to make courses on drones (not my specialty), but I might look into that in the future

Can you guide how to run the gazebo on ROS2 humble? I use Raspberry pi 4. Nice to hear from you?
@RoboticsBackEnd Рік тому
Unfortunately Gazebo won't run on Raspberry Pi (or with lots of errors). The architecture of the Pi is a bit different and not compatible with the 3D tools from ROS2. You'll have to use Gazebo on your own computer.

Hello, I was actually able to run the python script on visual code but I wasn't able to run my_first_node by using the ./ command in terminal. I am getting some sort of error on rclpy not being recognized. When I checked the import rclpy line, I received this error: "rclpy" is not accessed Pylance What does this mean? How do I fix this error?

This should work, but probably with additional config and bugs to resolve

It's doable. I use tmux and a windows x server to get it done but it kind of sucks. I'd rather just have a native Linux box and a docker container

41:11 Why we need to make the python file executable ?
@RoboticsBackEnd 3 місяці тому
When you build with --symlink-install it's going to use the file in your /src directly. Hence if it's not an executable, you'll get an error
@kayboku7281 4 місяці тому
Thanks for creating the course. Ive played with arduinos etc, built a few things, I just watched 2 hours of the course, is this really whats required to run things in ROS? Seems so overly complicated. I thought ROS was meant to make programming robots simple. (thats not meant to sound like a complaint, more of an an enquiry or question).
@RoboticsBackEnd 4 місяці тому
ROS is kind of a "framework", and basically for any framework you first need to learn quite a lot of things to get started. Then, as you are more comfortable with it, this is where you will see that it makes developing much easier and faster. Then, one thing I can agree with, is that ROS2 is clearly not an easy framework to start with. That's the main problem I try to solve in my courses :)

I install VMware on my laptop to install Ubuntu. After I installed Ros2 Humble for both virtual machine and Raspberry pi4. I started testing the link between VM and raspberry with the sample node above (ROS2 Humble). I pinged rasp's IP on the VM and got a signal and at the rasp screen I pinged the ip address of the virtual machine and got a response. But when transmitting "Talker" on virtual machine it shows "Hello world 1,...." but on raspberry screen "Listener" does not receive "Hello world...". Looking forward to hearing from you. Sincerely thank you
@RoboticsBackEnd 11 місяців тому
Hard to really know what could be the issue. It could come from the VM, as it's another layer on top of your OS, so it could mess with the network. Also, make sure that you're publishing and subscribing to the exact same topic name.
