Robot Operating System
The Robot Operating System (ROS) is a popular software toolkit that helps robotics engineers create and manage robot applications. Think of it like a universal language and set of tools that different robot parts can use to work together. It's not an operating system like Windows or Mac, but rather a collection of software tools that make it easier to build robot applications. Engineers use ROS because it provides ready-made components for common robot tasks, saving time and effort in development. It's widely used in research, industrial robotics, and autonomous systems like self-driving cars.

Example Interview Questions
Senior Level Questions
Q: How would you architect a multi-robot system using ROS?
Expected Answer: A senior candidate should explain how they would organize communication between multiple robots, manage data sharing, and ensure reliable operation. They should mention practical examples from past projects.
Q: What experience do you have with ROS2, and how does it compare to ROS1?
Expected Answer: They should be able to explain the key differences between versions, particularly in terms of reliability and security improvements, and discuss migration strategies.
Mid Level Questions
Q: How do you handle sensor integration in ROS?
Expected Answer: Should be able to explain how different types of sensors (cameras, lidar, etc.) can be connected and how their data is processed in a robot system.
Q: Explain how you would implement basic robot navigation using ROS.
Expected Answer: Should describe the process of setting up maps, planning paths, and controlling robot movement using ROS tools.
Junior Level Questions
Q: What are ROS nodes and topics?
Expected Answer: Should be able to explain that nodes are individual programs that communicate through topics, like different parts of the robot talking to each other.
Q: How do you create a basic ROS package?
Expected Answer: Should demonstrate understanding of the basic structure of a ROS project and how to create simple programs within it.
