In wheeled mobile robots, what is 'skid steering'?
  • A. Steering using a separate pivot wheel
  • B. Rotating each wheel at different speeds to turn
  • C. Fixed steering angle
  • D. Flying mode
Correct Answer: B
Explanation:
Skid steering turns by differentially driving wheels on each side.
Related Question 4
What is the main benefit of using a parallel kinematic robot structure?
  • A. Lower cost
  • B. Higher stiffness and precision for certain tasks
  • C. Requires fewer motors
  • D. It can hover
Correct Answer: B
Explanation:
Parallel structures, such as delta robots, provide high stiffness and precision for tasks like pick-and-place.
Related Question 5
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.
