Related Question 4
How does inverse kinematics differ from forward kinematics in robotics?
  • A. Inverse computes joint angles from end position; forward does opposite
  • B. Inverse encrypts control data; forward decrypts it
  • C. Inverse is used for wheels; forward for arms
  • D. They are the same
Correct Answer: A
Explanation:
Inverse kinematics calculates joint parameters for a given end-effector pose; forward kinematics computes end pose from joint angles.
