Quick Questions

Shade in the A or B circle for each question.

1. Which answer defines robotics best for 1 mark?

A Robotics is a machine that looks like a person and walks around.

B Robotics is the branch of technology that deals with the design, construction and use of robots.

2. Which sentence uses the key terms correctly to describe a robot's control system?

A An actuator sends data to the sensor, which processes it and tells the microprocessor to move.

B A sensor sends data to the microprocessor, which processes it and tells the actuator to move.

3. Which answer links a characteristic of a robot to a reason?

A A robot is programmable, so it can be given instructions to repeat a task.

B A robot is programmable.

4. Which answer correctly lists the three characteristics of a robot?

A Mechanical structure, electrical components and programmable.

B Human shape, a face and the ability to talk.

5. A student writes: 'A robot must look like a person.' Which response is correct?

A Incorrect. A robot only needs a mechanical structure, electrical components and a program, so a factory arm is a robot.

B Correct. If it does not look like a person, it cannot be a robot.

3Describing the three characteristics of a robot with the correct key terms		CA full-mark answer names the sensor, microprocessor and actuator and says what each one does.
4Giving an advantage in context with a reason		DA point is linked to a reason: the characteristic (program) is followed by why it matters.
5A robot must look like a person.		EThis gives no reason. It should state a specific advantage, such as working continuously without breaks, and explain why it helps.

Answer Key

Writing exam answers about robotics

Section A: Quick Questions

B — Robotics is the branch of technology that deals with the design, construction and use of robots.

B — A sensor sends data to the microprocessor, which processes it and tells the actuator to move.

A — A robot is programmable, so it can be given instructions to repeat a task.

A — Mechanical structure, electrical components and programmable.

A — Incorrect. A robot only needs a mechanical structure, electrical components and a program, so a factory arm is a robot.

Section B: Match the Pairs

A robot senses, processes and acts. → A full-mark answer names the sensor, microprocessor and actuator and says what each one does.

It is programmable, so it can repeat a task. → A point is linked to a reason: the characteristic (program) is followed by why it matters.

Describing the three characteristics of a robot with the correct key terms → Mechanical structure + electrical components + programmable

Giving an advantage in context with a reason → Robots do dangerous work, so humans stay safe.

A robot must look like a person. → A robot does not have to look like a human. It only needs a mechanical structure, electrical components and a program.

Robots are good because they are good. → This gives no reason. It should state a specific advantage, such as working continuously without breaks, and explain why it helps.

Section C: Definitions

key terms and reasons — Use the key terms robot, sensor, microprocessor, actuator and program correctly, and link each point to a reason, e.g. a robot is programmable so it can repeat a task.

Section D: Fill in the Blanks

A robot runs a program of instructions
so it can repeat a task.

A sensor detects light, heat or distance
so the robot knows about its surroundings.

The microprocessor processes sensor data
and decides what the robot should do.

An actuator moves a robot arm, so the
robot can carry out its task.

A robot needs a mechanical structure,
electrical components and a program.

Section E: Spot the Error

A — A robot does not have to look like a person. It is defined by its mechanical structure, electrical components and program. The line should read 'Robot: a programmable machine'.

C — An actuator is the output part that makes something move. Measuring light is the job of a sensor. The line should read 'Actuator: moves the robot part'.

B — A robot repeats a task reliably because it is programmable, not because it tires. The reason should be 'because it follows a program'.

C — High cost is a disadvantage because the purchase price is large and many small firms cannot afford a robot. The line should say small firms may struggle.

D — The sensor only detects the part. The actuator is what moves the arm. The line should be 'a part; the actuator moves'.
