#python#oop#class#inheritance

Practice the ROS2 Python - OOP Node Creation coding problem in Python for ROS2. Browser-based execution with automated grading — no local ROS install required. 90% of engineers pass this challenge.

Problem Statement

Learn how to structure a ROS 2 node using Python's Object-Oriented Programming (OOP) principles. You'll create a class that inherits from Node and implements the standard ROS 2 node lifecycle.

Requirements

  • Import rclpy and from rclpy.node import Node
  • Define a class that inherits from Node
  • Call super().__init__("node_name") in __init__ with a string node name
  • Create at least one publisher, subscriber, or timer inside __init__
  • Call rclpy.init() and rclpy.spin(node) in main()

Input/Output Format

Output:

  • A running ROS 2 node that stays alive via rclpy.spin()

⚠️ Common Pitfalls

  • Forgetting to call super().__init__("name") — the node name must be a string.
  • Not calling rclpy.spin(node) — without it the node exits immediately.
  • Defining __init__ without self as the first parameter.
