update the notes section and add creating your first node in the ros2 using python, things to be covered

• create a basic ros2 python node with necessary comments
• make it executable
• document the process

• how to create a publisher subscriber node
• node implemented in C++ and python
• documentation

The suggested changes include;

• documenting learning of parameters

• document the learnings

Task

Goal 🥇 :

• Create a battery node
• Create a led panel node
• Create custom message for publishing battery state
• Create custom service type for setting led state via request/response

Conditions

1. The LED panel consist of 3 LED s with initial_state : [0 ,0, 0] this needs to be published to /led_state topic by the led_panel node, it also act as a server with the service set_led used to change the LED states to ON or OFF
2. The client node batter_node sends request to the service based on the battery status

• state 1 : full battery then set led_state : [0, 0, 0] (turn OFF all the LED s)
• state 2 : empty battery then set led_state : [0, 0, 1] (turn ON the last LED s)

alternate the battery state between FULL and EMPTY using timer or loop indefinitely it takes 4 second to drain the battery empty and 6s to fully charge it again.

The suggested changes include ;

• custom launch file for robot_news_station_app

The issue helps in improving the repository, the suggested changes include ;

• how to create a launch file in python
• build the launch packages
• initializing the launch package
• documenting the process and steps

Task

Goal 🥇 : create a service

• create a new service number_counter
• implement a counter reset

Count reset condition

• if the data of SetBool contains a True then reset counter_ = 0 .
• else don't do anything.

The service can be invoked in any of the following methods;

• create a client for calling the service.
• invoke it using ros2 service call directly from the terminal.

• Start a new learning series
• cover basics of the ros 2
• document the learning process

create a simple ros2 node with python oops implementation

• create new python file
• implement oops
• make it executable
• test with ros2 run
• document the process

The changes proposed are

• a publisher written in C++
• a subscriber written in C++
• corresponding documentation for creating both.

• create a publisher node in python and cpp
• create a subscriber node in python and cpp
• make the subscriber node subscribe to the original publisher and in turn publish its result to another topic.

implement ros2 service client and server in C++, the issue contains following updates to be done

• ros2 service server
• ros2 client without oops
• ros2 client with oops
• documentation for implementation

To add the documentation for creating a publisher and subscriber using python
