Types of robots (Digital Society HL)

IB Digital Society • Unit 3

Exam preparation

Practice the questions examiners actually ask

Our question bank mirrors real IB exam papers. Practice under timed conditions and track your progress across topics.

Contents

  • Sorted by how much it decides
  • The categories, and what each one is for
  • The types in the real world
  • Exam-style: naming the kind

The guide separates robots — industrial, service and social — from autonomous technologies — the internet of things, autonomous vehicles, drones and virtual assistants. The useful axis underneath both lists is how much the machine decides for itself.

The kinds placed by autonomy, from a caged arm that decides nothing to a vehicle deciding continuously.

KindExampleWhat makes it that kind
IndustrialA welding arm on a production lineRepeats a programmed path, usually behind a cage
ServiceA hospital delivery robotWorks among people, following a plan it can adapt
SocialA companion robot in a care homeInteracts with people as its actual purpose
Internet of thingsA smart meter or a connected doorbellSenses and reports, rather than moving
Autonomous vehicleA driverless taxiChooses its own actions continuously
Virtual assistantA voice assistant in a speakerActs on request, with no physical body
Not all of them move: A virtual assistant and a smart meter are autonomous technologies without being robots. Saying which category you mean keeps an answer precise.

Real-world examples you can name

Boston Dynamics' Spot — commercial sale from 2020

A four-legged robot that walks over ground wheels cannot manage, used for inspecting construction sites, refineries and nuclear facilities. Police trials prompted objections strong enough that some forces returned it.

Who it affected: Inspection workers kept out of hazardous places, and communities uneasy about policing use.

Waymo driverless taxis — public service in Phoenix from 2020; San Francisco from 2023

Vehicles carrying passengers with no human driver, using lidar, radar and cameras within mapped service areas. Incidents blocking traffic and obstructing emergency vehicles have made the terms of city permission the live question.

Who it affected: Passengers, other road users, and taxi drivers whose work is at stake.

The da Vinci surgical robot — US approval 2000

A surgeon operates instruments through a console rather than directly; the system filters hand tremor and scales movement. It is teleoperated, not autonomous — the classic example of a robot that augments rather than replaces.

Who it affected: Patients receiving less invasive surgery, and surgeons retraining for it.

Notice the middle one: The da Vinci surgical robot (worldwide, US approval 2000) is teleoperated: a surgeon moves the instruments through a console. It is not autonomous at all, and calling it an autonomous robot in an answer is a correctable error.

How this is tested — you have to name the kind of robot or autonomous technology in a scenario, and say why the kind matters. It comes up two ways:

Paper 1 — structured question

  • Part a: identify types of robot in a described setting
  • Part b: explain why a task needs a particular kind

Paper 2 — source-based question

  • Q1: read what a source says a machine does
  • Q2: explain a claim about an autonomous system
The trap: calling everything a robot: A smart speaker is an autonomous technology and not a robot. A surgical system is teleoperated and not autonomous. Precision here is cheap and it is marked.
