Which of the following is a common approach to robot motion planning?

  1. Random Sampling

  2. Artificial Intelligence

  3. Manual Control

  4. None of the above

Show answer
Correct Option: A
Explanation:

Random Sampling is a common approach to robot motion planning, where random points are generated in the robot's workspace and checked for collisions. If a collision-free path is found, it is used to move the robot.

What is the main objective of robot control?

  1. To move the robot to a desired position

  2. To maintain the robot's stability

  3. To avoid obstacles

  4. All of the above

Show answer
Correct Option: D
Explanation:

The main objective of robot control is to move the robot to a desired position, maintain its stability, and avoid obstacles.

Which of the following is a common type of robot controller?

  1. Proportional-Integral-Derivative (PID) controller

  2. Fuzzy Logic controller

  3. Neural Network controller

  4. All of the above

Show answer
Correct Option: D
Explanation:

Proportional-Integral-Derivative (PID) controllers, Fuzzy Logic controllers, and Neural Network controllers are all common types of robot controllers.

What is the difference between forward kinematics and inverse kinematics?

  1. Forward kinematics calculates the robot's position from its joint angles, while inverse kinematics calculates the joint angles from the robot's position.

  2. Forward kinematics calculates the robot's velocity from its joint velocities, while inverse kinematics calculates the joint velocities from the robot's velocity.

  3. Forward kinematics calculates the robot's acceleration from its joint accelerations, while inverse kinematics calculates the joint accelerations from the robot's acceleration.

  4. None of the above

Show answer
Correct Option: A
Explanation:

Forward kinematics calculates the robot's position from its joint angles, while inverse kinematics calculates the joint angles from the robot's position.

What is the Jacobian matrix of a robot?

  1. A matrix that relates the robot's joint velocities to its end-effector velocity

  2. A matrix that relates the robot's joint accelerations to its end-effector acceleration

  3. A matrix that relates the robot's joint torques to its end-effector force

  4. None of the above

Show answer
Correct Option: A
Explanation:

The Jacobian matrix of a robot is a matrix that relates the robot's joint velocities to its end-effector velocity.

What is the role of a robot's end-effector?
