[DOCS] Update ROS2 DIRECT Python documentation in exercises (gh-pages)

[aquintan4]

Some exercises already support ROS2 Python, but their documentation in gh-pages is missing or not updated with the current implementation of ros-direct.

The style must be the same as the one used in:

• https://jderobot.github.io/RoboticsAcademy/exercises/AutonomousCars/follow_line/

Scope

Update all exercises that:

• Appear in docs/exercise-status.md (humble-devel)
• Have Python ROS2 = ok
• Do not yet have proper ROS2 documentation in gh-pages

For each exercise, update the Robot API section following the same structure as the reference:

## Robot API

### HAL-based Implementation

### ROS 2-direct Implementation

#### ROS 2 Topics

#### Python

• Topics used in the exercise
• Whether they are mean to be publishers/subscribers
• Message types (interfaces)
• QoS (only if relevant)
• How/Why to use them in the exercise (if explanation needed)
• Python notes (spin, rate, callbacks, etc.,)

PR #3718 is a great example of how to contribute to fix the issue!

Hi @javizqh and @nikhilgupta,I hope you’re doing well. I have submitted my proposal for the 'Architecting a Scalable C++ Middleware & High-Performance HAL' project.As a final-year BCA student and contributor to OpenSCAD, I am very excited about extending C++ support for the Robotics Academy. I’ve already started exploring the RADI environment and the existing 'Follow Line' C++ implementation to prepare for the community bonding phase.If there are any specific areas in the codebase or initial bugs you’d like me to look at to better align with the project's goals, please let me know. I am looking forward to your feedback.

Hi @vishwakarmanilesh7398-driod, please do not mix things and do not comment in the issues your interest in GSoC-2026 (or your proposal will be ignored). The issues are just issues to improve our open source projects, just technical. We have RoboticsAcademy Discussions and JdeRobot Discussions for the candidate selection process of GSoC-2026, not the issues. And the submission deadline already finished some days ago, no more information from the candidates or feedback to them will be provided now.
