Emerging Technology

Robotics, IoT, VR, blockchain and quantum

This unit covers technologies that are real, early and heavily oversold, and separating the working part from the promotion is most of the skill.

It covers robotics, the Internet of Things, virtual and augmented reality, blockchain, and quantum computing.

This unit breaks down into 23 short steps and 119 questions, starting at difficulty 1 and building to 5. Below you can see exactly what it covers, how the path is structured, and worked examples with explanations.

Where this fits

Best late in the track.

Where people slip

Quantum computers are not simply faster computers. They offer speed-ups for a narrow class of problems and nothing for most of what computers actually do.

How the unit is structured

Emerging Technology runs as 23 short steps that unlock in order. 17 are practice rounds and 6 are challenge rounds that pull together everything before them. Questions start at difficulty 1 and climb to 5 as you progress.

A hard drive is a normal storage device, while qubit, superposition and quantum are all quantum ideas.
Guess the numberLevel 3
11. A single classical bit can represent how many different values?
Answer: 2
A classical bit is either 0 or 1, so it has exactly 2 possible values.
Choose all that applyLevel 3
12. Which of these are true about quantum computing? Select all that apply.
- It uses qubitscorrect
- Qubits can be in superpositioncorrect
- It is a promising but still developing fieldcorrect
- It has fully replaced normal computers

Robotics

Multiple choiceLevel 1
13. Which part helps a robot sense the world around it?
- A sensorcorrect
- A sticker

A sensor gathers information, like light, distance or touch, so the robot can react.
Choose all that applyLevel 2
14. Which of these do most robots have? Select all that apply.
- Sensorscorrect
- Motors or moving partscorrect
- A controller or computer programcorrect
- Real human emotions

Fill the blankLevel 2
15. The motors and moving parts that make a robot move are called ____.
- actuatorscorrect
- sensors
- pixels
- passwords
Actuators are the parts, like motors, that turn a robot's decisions into movement.
Odd one outLevel 2
16. Which one is NOT a part of a typical robot?
- A bicycle bellcorrect
- A sensor
- A motor
- A controller
A bicycle bell is not a robot part, but sensors, motors and controllers are.
Put in orderLevel 2
17. Put these robot steps in order, from first to last.
Answer: A sensor gathers information -> The controller decides what to do -> The actuators move the robot
A robot senses first, then its controller decides, then its actuators move.
Sort into groupsLevel 3
18. Sort each robot by where it is mainly used.
Answer: Robot vacuum = Home; Welding arm = Factory; Assembly robot = Factory; Mars rover = Space

Where these questions come from. Each unit starts as a plan of the concepts it should cover and the difficulty it should span. Questions are written against that plan with AI assistance, then checked by a validator that rejects anything without a single defensible answer, an explanation, or plausible wrong options. How we write questions sets out the whole process, and corrections are fixed in the bank and reach the site and the app the same day.

How you practise

This unit mixes 10 different question formats, so you are recalling and applying rather than recognising the same layout every time.
