IMU
An IMU (Inertial Measurement Unit) is like a navigation and balance system for robots and automated machines. Think of it as an inner ear for robots - it helps them know which way is up, how fast they're moving, and in which direction they're heading. This technology is essential in everything from self-driving cars to drones and industrial robots. When you see IMU in a resume, it usually means the person has experience working with motion sensing and navigation systems in robotics projects. Similar terms you might see are "motion sensors," "orientation sensors," or "inertial sensors."

Example Interview Questions
Senior Level Questions
Q: How would you handle sensor fusion with IMU data in a robot navigation system?
Expected Answer: A senior candidate should explain how they combine IMU data with other sensors to improve accuracy, mentioning real project examples and problem-solving approaches in simple terms.
Q: What strategies do you use to deal with IMU drift and calibration?
Expected Answer: Should discuss practical solutions for maintaining sensor accuracy over time, including regular calibration procedures and error correction methods they've implemented in actual projects.
Mid Level Questions
Q: Can you explain how you've used IMU data in previous robotics projects?
Expected Answer: Should be able to describe specific examples of implementing IMU sensors in robots, explaining what problems they solved and how they processed the sensor data.
Q: What challenges have you faced when working with IMUs and how did you overcome them?
Expected Answer: Should discuss practical problems like noise reduction or integration with other systems, and explain their solutions in clear, non-technical terms.
Junior Level Questions
Q: What is an IMU and what does it measure?
Expected Answer: Should be able to explain in simple terms that an IMU measures movement and orientation, like how a smartphone knows when you rotate it.
Q: What basic applications of IMUs in robotics are you familiar with?
Expected Answer: Should mention common uses like helping robots balance, navigate, or maintain position, with basic understanding of how the sensor data is used.
