I made a walkthrough for husarion docs rosbot XL

Site Feedback
1

Currently I am on the the second unit i.e Creating nodes– messages

I’ll continue to complete it over the course of this month (I have my summer vacations and husarion docs is my top priority right now)

The repository contains all the notes on everything i learnt, all the problems i faced, all the concepts i had to learn separately including but not limited to ***c++ and object oriented programming fundamentals, parts of os fundamentals (especially threads) (I add the rest as and where required)

For context, I am using the docs in simulation, native ROS2 humble , ROSBOT_XL

I have further added

contribution instructions and projects (ideas right now, will add walkthroughs once I finish my docs)

current contribution instructions (can change as per your advice ) :

If you wanna contribute to this repository:

1. you may help with the formatting using # or ## for headings, > for notes, code between two sets of ``` above and below the code, and adequate spacing

2. If you’re from Husarion team, feel free to mention and use parts of my repository as and where needed, just make sure to credit me atleast once in the page used (doesn’t need to extravagant)

3. Adding missing explanations, improving examples

Fixing mistakes or outdated information



Improving tutorials or walkthroughs



Suggesting better learning resources (for e.g i tend to use ros2 humble docs and geeks for geeks for ros2 and c++ concepts respectively)



Creating FAQs



Improving troubleshooting sections



Adding screenshots or diagrams



Expanding setup guides(i generally don't write them cause they are pretty straight forward and haven't faced any problems yet)

4. Improving navigation and organization by adding hyperlinks / wiki links like

```

[alt-test](/path-to-file)

```

5. Help port this walkthrough to jazzy once Husarion docs is updated (Husarion team mentioned to me that soon the docs will be updated to ros2 jazzy)

6. Add project suggestions under [Project_suggestions.md](/ros2-roadmap-ultralab/projects/Project_suggestions.md).

Format for project suggestions :

Tag(begineer/intermediate/advanced)



one-line introduction of what to make



point wise features of the project



learning outcomes 



Links and credits

e.g

```

- Begineer project :

\*\*what you'll make--\*\*
