Unit 6

Question 1

What is an automated system?

Answer 1

An automated system is a computer system that collects information and can react and perform tasks based on the data

Automated systems are made using three components:

Sensors

Microprocessors

Actuators

A sensor collects information and provides the microprocessor with it as an input

A microprocessor processes the information and makes decisions based on pre-programmed rules

An actuator makes physical changes based on instructions given by the microprocessor (outputs)

Question 2

What is robotics?

Answer 2

Robotics is the principle of a robot carrying out a task by following a precise set of programmed instructions

Question 3

What are dumb robots?

Answer 3

Repeat the same programmed instructions over and over again (no AI)

Question 4

What are smart robots?

Answer 4

Carries out more complex tasks and can adapt and learn (AI)

Question 5

What are the characteristics of a robot?

Answer 5

Mechanical structure

Electrical components

Programmable

Question 6

What is artificial intelligence?

Answer 6

Artificial intelligence (AI) is a machine that can simulate intelligent behaviours similar to that of a human

Question 7

What type of system is AI?

Answer 7

AI is a system that can:

Learn - acquire new information

Decide - analyse and make choices

Act autonomously - take actions without human input

Question 8

What are the two types of AI?

Answer 8

There are two main types of AI:

Weak AI, also known as narrow AI, is designed to perform a specific task or set of tasks

Strong AI, also known as artificial general intelligence (AGI), is designed to perform any intellectual task that a human can do

Question 9

Characteristics of AI

Answer 9

Characteristics of AI
AI shares three common characteristics:

Collection of data

Rules for using data

Ability to reason

Question 10

What is an expert system?

Answer 10

An expert system mimics human knowledge and experience and uses a combination of the two to solve problems or answer questions

Question 11

What is machine learning?

Answer 11

Machine learning is one method that can help to achieve an artificial intelligence (AI)

By giving a machine data so that it can ‘learn over time’ it helps towards training a machine or software to perform a task and improve its accuracy and efficiency

Uses algorithms to analyse data and identify patterns or relationships
