A robot has some degree of autonomy when it can sense conditions, process information and select or perform actions with limited human intervention. Autonomy exists on a spectrum, so it does not mean that the robot has complete independence, consciousness or free will.
This is part of Robots and autonomous technologies, a topic shared by SL and HL students. A robot typically combines three functions:
- Sensing: Sensors collect data about the robot or its environment, such as distance, temperature or location.
- Processing: Software uses rules, algorithms or machine-learning models to interpret the data and select an action.
- Acting: The robot affects its environment, for example by moving, stopping or manipulating an object.
The phrase "some degree" matters because human control can occur at different points.
| Degree of independence | How the system operates | Human role |
|---|---|---|
| Low | Performs a fixed action when directly instructed | A person initiates and controls most actions |
| Moderate | Responds to sensor data within predefined rules | A person sets goals, limits and operating conditions |
| Higher | Selects among several actions in changing conditions | A person supervises and may override decisions |
Automation and autonomy are related but not identical. An automated factory arm may repeat a programmed movement without adapting, while a warehouse robot may detect an obstacle and choose another route. The second system demonstrates greater autonomy because it adjusts its behaviour using environmental data.
A common misconception is that autonomy means the robot "thinks for itself." In Digital Society, autonomous behaviour results from interacting hardware, data, algorithms and human-designed objectives. Designers, operators and organizations still shape what the system can perceive, prioritize and do.
Exam technique: For an AO1 describe question, identify sensing, processing and acting, then explain the robot's level of human independence. For AO2 or AO3, analyse how human choices, operating limits and possible unintended consequences affect people and communities.
