What is the purpose of inverse kinematics in a robotic arm?
  • A. To compute the joint movements needed for a desired end-effector position
  • B. To encrypt robot control signals
  • C. To linearize sensor inputs
  • D. To measure force and torque
Correct Answer: A
Explanation:
Inverse kinematics calculates how to move joints so the robot's end-effector reaches the target position.

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.
