mjavadzallaghi / ros2_learning

A useful collection of CPP and PYTHON examples to learn ROS2 from zero

ROS2 C++ PYTHON learning

A useful collection of rclcpp and rclpy examples to dive into ROS2

This repository has the goal to help the learning process of ROS2 basic, middle and advance features through a collection of example nodes ready to compile and use. All the nodes have been tested with ROS2 HUMBLE

Folders tree

CPP

All the subfolders cover a specific feature and include their own CMakeLists.txt and package.xml files, so you can copy and paste the single subfolder unit and put it into your ROS2 workspace to compile them

• 01 Start with simple nodes
  • my_first_node.cpp
  • node_with_class.cpp
  • node_timer_without_class.cpp
  • node_timer_with_class.cpp
• 02 Publisher and subscriber
  • simple_publisher_node.cpp
  • simple_subscriber_node.cpp
