A breakdown on the road: who does what?

ICT Prep 2 Term 1, Unit 1, Lesson 1: pp. 6–9
GoalDescribe a roadside breakdown as a three-step story and say who does what.
New words
sensor · a small part that measures something, such as heat or pressure, and reports itGPS · a system that tells a device exactly where it isprobable cause · the most likely reason for a fault, suggested from the datarepair robot · a machine sent to inspect a vehicle and fix small faults
Explanation

Imagine a car that stops at the side of a quiet road because of an engine problem. A connected smart system can help in three steps. First, sensors inside the engine notice that something is wrong. The IoT part sends a message with the fault and, using GPS, the exact place of the car. Second, the AI looks at the data. From many earlier cases it suggests a probable cause, for example that the engine is too hot, and it suggests a plan: stop, wait, help is coming. Third, the action: a repair robot, if there is one, is sent to inspect the car and fix a small fault, or a tow vehicle is called for a bigger one. Systems like this are being developed, and many places still use people for every step. The AI only suggests, so a person still checks the result.

PartIts job in the storyWhat it handles
IoTsends the fault and the placesensor readings, GPS position
AIanalyses the problem and decidesprobable cause, suggested plan
Roboticsdoes the repair or the helptools, a part to replace, a tow call
Worked examples
A delivery van’s tyre sensor reports low pressure. The system sends this to a workshop. The AI notices that the same van lost pressure twice this month and suggests checking the tyre. A mechanic or a service robot then does the check.
AI suggestsrobot or person repairs
Nour thinks the AI part could repair the engine by itself. Her teacher explains: AI is a program, it has no hands. It can suggest the cause and the plan. A robot or a person does the repair.
Class activity

Write your own roadside story with a different fault, for example a bicycle chain or a bus engine. Use three short sentences: what the sensor sends, what the AI suggests, what the robot or a person does. Check that nobody is hurt in your story.

Practice
1
Which part finds the car’s exact place?
2
What does the AI suggest in the story?
3
What happens if the robot cannot fix the fault?
4
Match the part to its job: IoT, AI, robotics.
