SummaryThe whole chapter in one scroll
- Robotics = a robot carrying out a task by following a precise set of programmed instructions.
- Robots split into dumb robots (repeat the same instructions, no AI, e.g. car assembly line) and smart robots (adapt and learn using AI, e.g. surgical assistants).
- The rise of AI and robotics raises ethical/legal issues: accountability, safety, algorithmic bias, legal liability.
- Every robot shares three characteristics: mechanical structure, electrical components, and being programmable.
- Robots play real-world roles across industry, transport, agriculture, medicine, domestic life, and entertainment — each with its own advantages and disadvantages.
1. What is Robotics?Definitions, dumb vs smart robots, ethical issues
The core definition
Here's the exam-safe definition you need to know cold: robotics is the principle of a robot carrying out a task by following a precise set of programmed instructions. Notice what that definition does not say — it doesn't say the robot has to be intelligent, or think for itself. At its most basic, a robot is just a machine executing a program, the same way your calculator executes a program when you press "=". The difference is that a robot's program controls physical movement in the real world, not just numbers on a screen.
Because "following instructions" can mean very different things depending on how rigid or flexible those instructions are, CIE splits robots into two categories you must be able to compare.
Dumb robots vs. Smart robots
Think of a dumb robot like a vinyl record: it plays the exact same groove every single time, no matter what's happening in the room around it. A smart robot is more like a musician improvising — it's still following rules of music, but it's constantly reacting and adjusting to what it hears.
| Dumb robots | Smart robots |
|---|
| Repeat the same programmed instructions over and over again. No AI involved — they cannot adapt if something changes. |
Carry out more complex tasks and can adapt and learn. Powered by AI. |
| Example: a robotic arm on a car assembly line, welding the same spot on every car body that passes by. |
Example: a robot assisting surgeons in delicate procedures, adjusting its movements based on live feedback. |
Quick test
Ask yourself: "If the environment changed unexpectedly, would this robot notice and react?" If no → dumb robot. If yes → smart robot (AI).
Ethical & legal issues raised by AI and robotics
As machine learning and robotics get more capable, they start making decisions that used to require a human — and that creates genuine problems society hasn't fully solved yet. CIE wants you to be able to name four of them:
- Accountability
- Safety — can the robot be trusted not to injure people, especially when working alongside humans?
- Algorithmic bias
