Kronos Robotic Work Cell

A six-axis robotic work cell modelled end to end in ELANG as an audited reference — roughly a thousand lines carrying a functional-safety design to ISO 13849-1 Performance Level d, with every safeguard traced to the hazard it mitigates.

STANDARDS

What this class is held to

The recipe for this system class encodes its standards as tracked obligations, so the design is proven against them rather than tested against them at the end.

  • ISO 10218
  • ISO 13849-1 (PL d)
  • ISO 230
THE MISSION NEED

A safeguard is only real if it traces to a hazard and a test

On a machine that can injure, the hard part is not drawing the guarding — it is proving that every hazard has a safeguard, every safeguard a means of detection, a responsible actor and a lifecycle gate. The Kronos model is the reference for that closure: the WHY pillar's hazards and safeguards are wired to the HOW pillar's tests and the WHO/WHEN pillar's gates.

THE PATH

Machine recipe over the baseline lifecycle

Model a work cell whose functional-safety case is complete and traceable, to ISO 13849-1 PL d, with the safety chain checkable rather than asserted.

  1. 01Frame the cell's capabilities and the environment it operates in
  2. 02Enumerate hazards and the safeguards that mitigate them
  3. 03Tie each safeguard to a detection means, a responsible actor and a gate (WFR-9)
  4. 04Allocate the safety functions onto components and interfaces
  5. 05Close the verification matrix and reach L2 conformance

THE GATE

TRR — Test Readiness Review

Before test, the safety case and the models have to line up.

  • The digital replica correlates with the analytical models
  • Abort criteria and safety cases are agreed
  • Every hazard has a safeguard with an assigned verification
  • Test procedures exist for every safety function

ELANG's well-formedness rules refuse to call the model complete while an obligation lacks an implementation, a test, an actor or a gate.
