Robotics, automation and their impacts
Evaluate the benefits, limits and consequences of robots and automated systems in industry, farming, medicine and daily life.
Mapped to the Cambridge IGCSE Computer Science 0265 syllabus for exams in 2029. These original explanations and self-checks are independent study support, not Cambridge papers, official marks or grades. Practical programming is taught with worked code and trace tasks; an executable Python workspace and timed digital-exam simulation are not yet available.
Before you begin
- Use the 2029 syllabus for this course. Cambridge specifies Python 3.10 or higher for programming and digital exams for both components. The syllabus currently identifies this route for 2029 only; confirm later-year availability with Cambridge and your school.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Before robotics, automation and their impacts, which statement is the safest starting point?
What you will learn
- Describe robot characteristics and applications
- Evaluate advantages and disadvantages in specified contexts
- Discuss employment, safety and sustainability implications
Robots combine structure, electronics and programs
Robotics is the design, construction, operation and use of robots. A robot has a mechanical structure, electronic components such as sensors, controllers, motors, actuators, networking hardware and a power supply, and programmable behaviour.
Robots can work in industry, agriculture and medicine. Their suitability depends on task precision, environment, cost, need for human judgement, safety and how predictable the work is. Automated systems are also used in transport, domestic settings and retail.
Evaluate effects from more than one viewpoint
Automation can increase consistency, operate continuously and perform dangerous or repetitive tasks. It may also require high setup and maintenance costs, fail when conditions change, or reduce some kinds of employment while creating demand for different skills.
Safety, employment and environmental sustainability are explicit evaluation themes. Consider who benefits, who bears a risk, what happens if a system fails, and how energy, materials or waste change. A balanced answer uses a context-specific judgment rather than claiming automation is always good or bad.
Pause and explain
Which habit best checks your understanding of robotics, automation and their impacts?
Worked example
A farm uses a robot to apply water only to dry areas. Give one benefit and one limitation.
Show the worked solution
- Targeted watering can reduce water use compared with watering the whole field.
- Sensors and robots need purchase, calibration and maintenance.
- A failure or poor sensor reading may leave crops dry or waste resources.
Answer It can conserve water, but depends on reliable sensors and maintenance.

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.
Evaluate using robots for a repetitive task on an assembly line. Include one advantage, one disadvantage and a judgment.
Give me a hint
Balance consistency or safety against cost, flexibility or jobs.
Compare my reasoning
- Robots can repeat precise movements and work for long periods, improving consistency.
- Purchase, programming and maintenance cost money; robots may also struggle with unexpected changes.
- They are suitable when the task is stable and the gains justify costs, with staff retrained for new roles where possible.
Robots suit stable repetitive tasks when benefits outweigh costs and safety/workforce changes are managed.
Look for these in your work
- Context benefit
- Context risk
- Reasoned judgment
A hospital considers a robot to deliver supplies between wards. Explain two benefits and one safety concern.
Give me a hint
Consider staff time, consistency and the risks of movement around people.
Compare my reasoning
- It can deliver routine supplies consistently and free staff time for patient care.
- It can work across repeated routes and reduce manual transport workload.
- It must safely detect people and equipment; a navigation failure could cause a collision or delay.
Routine delivery can save time, but navigation and fail-safe behaviour must protect patients and staff.
Look for these in your work
- Two benefits
- Specific safety risk
- Context linked
A retailer replaces staffed checkout lanes with automated systems. Discuss implications for employment, safety and sustainability before recommending a balanced approach.
Give me a hint
Consider workers, user access, equipment, energy and failure handling.
Compare my reasoning
- Some checkout roles may reduce, while technical maintenance roles may grow; retraining can support workers.
- Systems need privacy/security protections and a staffed alternative for errors or users who need help.
- Equipment uses energy and materials; overall impact depends on lifespan, use and waste handling.
Use automation for suitable transactions while retaining human support, securing data and planning worker transition and equipment lifecycle.
Look for these in your work
- Employment addressed
- Safety/access addressed
- Sustainability and judgment
Common mistakes
- Listing advantages without addressing the named context.
- Treating job loss as the only social impact.
- Making an evaluation with no evidence or condition.

Make it stick
How can a balanced evaluation connect a robot’s function to employment, safety and environmental effects?
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.
