Compare roles for robots in different sectors
Match robot tasks to settings such as industry, transport, agriculture, medicine, homes and entertainment.
This sequence follows Cambridge IGCSE Computer Science 0478, 2026–2028 syllabus Version 6. It covers subject content sections 6.1–6.3 only. The separately published 2029–2031 syllabus is not mapped here. Practice is original, self-checked and does not award an official Cambridge grade. Full timed papers and human subject-teacher review remain outstanding.
Before you begin
- No programming language is required. Be comfortable with place value and multiplication; each lesson introduces the computer-science notation it uses.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which is a plausible agricultural robot role?
What you will learn
- Identify robot roles in specified sectors
- Explain why a robot suits a particular task
- Compare benefits and drawbacks
Robot roles depend on the environment
Robots can perform tasks in industry, transport, agriculture, medicine, domestic settings and entertainment. A factory robot may move heavy parts; a drone can inspect crops; a medical robot may assist a clinician with precise movement.
Apply and check the rule
Robots can increase consistency, reach difficult spaces or take on dangerous repetitive tasks. Their limits include purchase and repair cost, safety risks near people, dependence on programming and reduced flexibility when conditions change. In medicine or care, robots assist but do not automatically replace professional judgement.
Pause and explain
Which is a relevant drawback of a medical robot?
Worked example
A farm needs to inspect a large field for crop problems. Give a suitable robot role and one limitation.
Show the worked solution
- A programmed drone can survey crop areas.
- Sensors or cameras collect images for analysis.
- Weather, battery life and the need to verify findings are limitations.
Answer A drone can survey crops quickly, but flight time and weather limit coverage and a person should verify important findings.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Give one suitable robot task in industry and one in domestic settings.
Give me a hint
Choose tasks that benefit from programmed movement or repetition.
Compare my reasoning
- Industry: move heavy parts on an assembly line.
- Home: vacuum floors or assist with a repetitive chore.
- Both need safe programming and maintenance.
A factory robot can move heavy parts; a domestic robot can vacuum floors. Both need safe operation and maintenance.
Look for these in your work
- Industrial role
- Domestic role
- Shared condition
Explain one advantage and one limitation of using a robot to deliver supplies in a hospital.
Give me a hint
Consider repeated movement and shared spaces with patients.
Compare my reasoning
- A robot can move supplies consistently and reduce staff walking time.
- People and equipment create safety obstacles in corridors.
- The robot needs reliable navigation and staff oversight.
It can deliver supplies efficiently, but it must navigate safely around people and staff need a fallback if it fails.
Look for these in your work
- Relevant benefit
- Contextual risk
- Control
A clinic proposes a robot to assist with surgery. Evaluate the proposal without claiming that the robot replaces the clinician.
Give me a hint
Balance precision and repeatability with patient safety and oversight.
Compare my reasoning
- A programmed robot may support steady, precise movement.
- Equipment cost, failure and patient-specific conditions create risks.
- A trained clinician must supervise, decide and respond to unexpected conditions.
A robot may assist with precise movements, but it must be carefully tested and supervised. The clinician retains responsibility for judgement and unexpected events; use is justified only if the safety and performance gains outweigh cost and risk.
Look for these in your work
- Task benefit
- Risks
- Human responsibility
- Judgement
Common mistakes
- Claiming a robot independently makes every medical decision
- Ignoring the setting when evaluating a use
What can you explain now?
Why might a robot be useful for a hazardous industrial task?
Compare with the explanation
It can reduce direct human exposure to danger
A programmable robot can perform the risky movement while people supervise from safer positions.

Make it stick
Give one role for robots in two different syllabus sectors and a context-based trade-off.
If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
