Sensor Fusion
Sensor Fusion is like combining information from multiple sources to get a more complete picture - similar to how humans use both eyes and ears to understand their surroundings. In robotics and self-driving cars, it means taking data from different sensors (like cameras, radar, and other measuring tools) and combining them to help machines understand and react to their environment more accurately. Think of it as giving robots and autonomous systems multiple "senses" and then helping them use all these senses together to make better decisions.

Example Interview Questions
Senior Level Questions
Q: How would you approach integrating multiple sensors with different update rates in a real-time system?
Expected Answer: A strong answer should explain how they would handle timing issues between different sensors, manage data synchronization, and ensure reliable system performance. They should mention practical examples from previous projects.
Q: What strategies would you use to handle sensor failures in a critical system?
Expected Answer: Look for answers that discuss backup systems, fault detection methods, and graceful degradation of system performance. They should emphasize safety considerations and real-world implementation experience.
Mid Level Questions
Q: Can you explain how you would combine data from a camera and radar sensor?
Expected Answer: They should be able to explain in simple terms how different types of sensors complement each other and basic methods for combining their data to get better results.
Q: What methods would you use to test a sensor fusion system?
Expected Answer: Look for answers that discuss testing with recorded data, simulation testing, and real-world testing approaches. They should mention ways to validate system accuracy.
Junior Level Questions
Q: What is the basic purpose of sensor fusion?
Expected Answer: Should be able to explain that sensor fusion combines data from multiple sensors to get more accurate and reliable information than using just one sensor alone.
Q: Can you name some common sensors used in robotics?
Expected Answer: Should be able to list basic sensors like cameras, radar, lidar, and explain their basic functions in simple terms.
