Forward Kinematics
Forward Kinematics is a basic concept in robotics that helps predict how robot arms and joints will move. Think of it like planning the path that a robot's hand will take to reach a specific point. It's similar to how you can predict where your fingertip will end up when you move your arm in a certain way. Robotics engineers use Forward Kinematics to program robots for tasks like assembly lines, manufacturing, or even surgical procedures. This is one of two main ways to control robot movement, with the other being Inverse Kinematics. When you see this term on a resume, it usually indicates that the candidate understands how to make robots move precisely and safely.

Example Interview Questions
Senior Level Questions
Q: How would you implement Forward Kinematics in a complex robotic system with multiple joints?
Expected Answer: A senior candidate should explain in simple terms how they would map out the movement of each joint, consider safety limitations, and implement error checking. They should mention experience with real-world applications and problem-solving strategies.
Q: How do you handle accuracy issues in Forward Kinematics calculations?
Expected Answer: The answer should cover practical methods for improving precision, calibration techniques, and ways to verify calculations are correct. They should mention experience with different types of robots and common problems they've solved.
Mid Level Questions
Q: Can you explain the difference between Forward and Inverse Kinematics?
Expected Answer: They should be able to explain that Forward Kinematics calculates where the robot end will be based on joint positions, while Inverse Kinematics does the opposite - finding joint positions needed to reach a specific point.
Q: What tools have you used to implement Forward Kinematics?
Expected Answer: Should mention experience with common robotics software, simulation tools, and programming environments. They should be able to discuss practical applications they've worked on.
Junior Level Questions
Q: What is Forward Kinematics and why is it important in robotics?
Expected Answer: Should be able to explain the basic concept of predicting robot arm position based on joint angles, and why this is important for robot control and safety.
Q: Have you worked with Forward Kinematics in any projects?
Expected Answer: Should be able to describe basic projects or coursework where they applied Forward Kinematics concepts, even if just in simulation.
