The standard ISO 3691-4 specifies a clear procedure for achieving safety on an automated guided vehicle system, for both manufacturers and operators. It defines an automated guided vehicle system as a combination of one or more automated guided vehicles or autonomous mobile robots and the plant environment.
The 2020 publication of the standard ISO 3691-4 for automated guided vehicle systems and autonomous mobile robots was a reaction to the rapid development of new technologies in the field of automated vehicles. The ISO standard was long overdue, as its predecessor (EN 1525:1997) had been published 23 years previously. It can now be regarded as the most important international standard for automated guided vehicle systems. In Europe, ISO 3691-4 is supplemented by the standard EN 1175:2020, which refers to specific electrical aspects of self-propelled industrial trucks (including automated guided vehicle systems).
In addition to the international launch of ISO 3691-4, the USA also updated the relevant standards in 2019 and 2020: ANSI/ITSF B56.5:2019 (automated guided vehicle systems) and ANSI/RIA R15.08-1:2020 (autonomous mobile robots).
