Autonomous physical systems

Autonomous vehicles, drones, industrial and service robots sense their surroundings and act in the physical world, where errors can injure people and damage property. Their safety depends on perception, decision-making, fallback behaviour and the environments they are allowed to operate in. This page sets out how autonomous physical systems fail, how their safety is assessed, and what evidence serves the regulators, operators and communities involved.

01In brief

The short answer.

Autonomous vehicles and robot safety is the field that covers machines that sense and act in the physical world without continuous human control, where errors can injure people. Safety depends on perception in rare situations, staying within the operating domain, handover to humans and structured safety cases.

04The question

Autonomous physical systems: how the risk develops.

Robots, sensors and controls. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Perception meets the unexpected

Sensors and models misread rare situations: unusual objects, poor weather, glare or confusing road layouts. Rare cases dominate risk because they are hard to test.

Mechanism

Operating domains set limits

Systems are designed for an operational design domain of roads, weather, speeds or spaces. Failures increase when systems are used outside it.

Mechanism

Handover to humans is hard

Supervisors lose attention when automation works most of the time, and cannot take over instantly when it fails.

Mechanism

Safety cases must be argued

Showing that a system is acceptably safe needs a structured argument combining design, testing, simulation and field data, because driving or operating enough to see rare failures is impractical.

05Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition

DisengagementA transfer of control from an automated system to a human, reported in some jurisdictions.
Collaborative robotA robot designed to work in shared space with people under safety limits.
06Indicators

What is measured, and how well.

Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.

07Canvas

From sources to decisions.

The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

10Core questions

What safety engineers ask.

  • Does the system perceive its environment correctly across weather, lighting and unusual objects?
  • How does it behave at the edges of its operating conditions, and does it know when it is outside them?
  • Can it fail safely, handing over to a person or stopping without creating new hazards?
  • How is safety demonstrated when learned components cannot be fully specified?
11Mechanisms

Where physical autonomy fails.

Perception is the weak link: cameras, lidar and radar each fail differently in rain, glare, dust or darkness, and learned perception models can misclassify rare objects. Planning must handle uncertain predictions of other agents' behaviour. Control must remain stable as conditions change.

Handover to humans is difficult because people monitoring automation lose situational awareness and may not respond in time. Classical safety engineering assumes components whose behaviour can be fully specified, which learned components are not.

12Methods and data

Assurance for systems that move.

  1. 01

    Operational design domain

    Defining the conditions a system is designed for and detecting when it leaves them.

  2. 02

    Simulation and scenario testing

    Testing across large numbers of simulated scenarios, using robotics and automation and high-performance, cloud and edge computing. Simulation fidelity limits what it can reveal.

  3. 03

    Safety cases

    Structured arguments, supported by evidence, that a system is acceptably safe for a use, drawing on AI evaluation and assurance engineering. A safety case is only as strong as its weakest evidence.

  4. 04

    Field monitoring

    Collecting incidents and near misses after deployment. Under-reporting is common.

14Questions

Questions and answers.

What is an operational design domain?
The conditions under which an automated system is designed to operate, such as road types, speeds, weather and time of day.
Are self-driving cars safer than human drivers?
Evidence is still accumulating. Fair comparison needs crash data with matched exposure, road types and conditions, which public reports often lack.
What is a safety case?
A structured argument, supported by evidence, that a system is acceptably safe for a specific use in a specific environment.
Are autonomous vehicles safer than human drivers?
It depends on the system, the conditions and how safety is measured. Comparisons need like-for-like conditions and enough exposure to observe rare events, which is why claims should be read with their data.
Can learned components be safety-assured?
Partly, through testing, monitoring and architectures that constrain them with simpler verified components. Assurance of learned components remains an active research area.
Does the platform test products?
No. It develops and publishes methods. Product testing and approval are the roles of manufacturers, testing bodies and regulators.
