Repeatability is the ability of a robot or motion system to return to the same taught position under identical conditions over repeated cycles, usually expressed as a small deviation such as ±0.02 mm. In manufacturing documents, it is listed beside payload and speed in robot specifications, and it is distinct from accuracy, which measures how close the reached position is to the commanded target.
Robot specification sheets, validation reports, and sales collateral all contain repeatability values. Translators encounter it when localizing datasheets for Asian, European, and North American markets, where decimal separators, micron-to-inch conversions, and terms such as “repeatability” versus “reproducibility” must be handled carefully. It also occurs in quality documentation when machine capability is compared with part tolerance.
A common error is translating repeatability as “accuracy” or “precision” without qualification. In manufacturing, these terms have distinct statistical meanings; using them interchangeably can mislead a buyer into believing a robot reaches commanded positions more exactly than it does. The error may cause a machine to be accepted for a process it cannot actually hold.
The EU Machinery Directive requires documentation in the language of the destination market. Safety-related terms must map exactly to the wording of the governing standard.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
