ENGINEERED STATES
Motion only
when safe.
Safety is part of the system architecture, not an accessory. Public presentation, robotic retrieval and service access require distinct controlled states.
01 / PRINCIPLES
Prevent access.
Verify position.
Stop safely.
| Garden-level interface | Locked against unintended opening and movement; load and entrapment risks assessed for the final lid design. |
|---|---|
| Robotic envelope | Physically guarded from users during automatic motion. |
| State verification | Position, cassette engagement, delivery interface and access closures checked before each transition. |
| Safe stop | Defined response to obstruction, sensor disagreement, power loss, communication fault or emergency demand. |
| Service mode | Authorised, controlled access with isolation and prevention of unexpected restart. |
| Recovery | A documented method to recover the bottle and equipment without creating uncontrolled motion. |
02 / VALIDATION
Safety requires evidence.
The final machine requires a documented risk assessment, safety-requirement specification, verified control architecture, guarding design, electrical documentation and validation testing. Applicable legal and technical requirements depend on the final product, installation and market.
Concept-stage boundaryNo website statement constitutes a safety rating, conformity declaration or permission to construct. Safety performance levels and component selections remain open until the risk assessment and detailed design are complete.
Acceptance evidence
The commissioning file should record inspection, functional tests, fault injection, stopping behaviour, access control, load cases, emergency recovery, instructions and training. Changes after acceptance require controlled review.
