Unit 3 - Introduction To Robotics- Practice Quiz

What is the definition of robotics?

• The study of computers

• The science of designing and building robots

• The art of painting

• The theory of relativity

Answer explanation

Robotics is defined as the science of designing and building robots, which distinguishes it from unrelated fields like computer science, art, or physics. The correct choice accurately captures this definition.

Which of the following is NOT a characteristic of a robot?

• Ability to move autonomously

• Capability to make decisions

• Requires constant human control

• Can perform tasks automatically

Answer explanation

A robot is designed to operate independently, making decisions and performing tasks automatically. Therefore, the characteristic 'Requires constant human control' is NOT true for robots.

Which of the following is NOT a characteristic of a robot?

• Autonomy

• Sensing

• Manipulation

• Emotion

• Programmability

Answer explanation

Emotion is not a characteristic of a robot, as robots operate based on programming and logic rather than feelings. The other options—autonomy, sensing, manipulation, and programmability—are essential traits of robotic systems.

What is the main difference between a robot and a machine?

• A robot can perform tasks autonomously, while a machine requires human operation.

• A machine can perform tasks autonomously, while a robot requires human operation.

• Both robots and machines require human operation.

• There is no difference between a robot and a machine.

Answer explanation

The correct choice highlights that a robot can operate independently, performing tasks autonomously, whereas a machine typically needs human input to function. This distinction is key in understanding their differences.

Which of the following are uses for robots in real life?

• Manufacturing, healthcare, and space exploration

• Cooking, painting, and singing

• Gardening, knitting, and storytelling

• Swimming, dancing, and sleeping

Answer explanation

Robots are widely used in manufacturing for automation, in healthcare for surgeries and patient care, and in space exploration for tasks like satellite repairs and planetary exploration, making this the correct choice.

Identify one of the laws of robotics.

• A robot may not injure a human being or, through inaction, allow a human being to come to harm.

• A robot must obey the orders given it by human beings, except where such orders would conflict with the First Law.

• A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

Answer explanation

The correct choice is the First Law of Robotics, which states that a robot must not harm a human or allow harm through inaction. This principle prioritizes human safety above all other robotic functions.

Which of the following is a historical fact about robots or robotics?

• The first industrial robot was installed in a General Motors plant in 1961.

• The first robot to walk on the moon was in 1972.

• Robots were first used in agriculture in the 1800s.

• The first humanoid robot was created in 2000.

Answer explanation

The first industrial robot, Unimate, was indeed installed at a General Motors plant in 1961, marking a significant milestone in robotics. The other statements are inaccurate regarding their historical timelines.

Name at least 3 components of the Mindstorm EV3 robot.

• EV3 Brick, Motors, Sensors

• Wheels, Gears, Axles

• Battery, Remote Control, Charger

• LED Lights, Sound Sensor, Camera

Answer explanation

The correct choice includes essential components of the Mindstorm EV3 robot: the EV3 Brick serves as the brain, Motors provide movement, and Sensors allow interaction with the environment.

Which of the following is a function of a component of the Mindstorm EV3?

• Detecting obstacles

• Flying

• Cooking

• Playing music

Answer explanation

The Mindstorm EV3 can detect obstacles using its sensors, making 'Detecting obstacles' a valid function. The other options, such as flying, cooking, and playing music, are not functions of the EV3 components.

How are robot sensors similar to human senses?

• Both can detect environmental changes.

• Both are used for communication.

• Both are used for movement.

• Both are used for energy production.

Answer explanation

Robot sensors, like human senses, can detect changes in the environment, such as light, sound, and temperature. This ability allows both robots and humans to respond to their surroundings effectively.
