AGV – AGVs are mobile robots that follow exact guide paths whether a physical or virtual “line.” If there is an obstacle in its travel path, the AGV will stop until the obstacle is removed.Industrial robots are also always governed by the safety standards found in ANSI/RIA 15.06. 08 applies to industrial robots if it is attached to a mobile AGV or AMR. Industrial Robots – Industrial robots are manipulators that have three or more degrees of freedom.R15.08 defines AGS, AMRs and Industrial Robots as follows: It also clarifies vehicle type based on intelligence and path planning capabilities rather than size, payload capacity, or localization method. The standard subsequently offers updated safety standards around these adaptive navigation functions.Īdditionally, the standard provides a helpful framework for understanding which safety standard to use for which robot platform. R15.08 defines an AMR as a platform that dynamically plans and adjusts its path within a structured or semi-structured environment. On the other hand, many customers refer to smaller, lightweight, deck-load mobile robots (used for order fulfillment applications primarily) as AMRs, while referring to any high-capacity vehicle such as tuggers and forklifts as AGVs – regardless of the navigation technology. Some AGV suppliers argue what constitutes an AMR is their use of LiDAR, vision, and/or fiducial-based navigation systems, combined with lower infrastructure requirements compared to the older magnet and wire-guided AGVs. In addition to ambiguity around relevant safety standards, the industry did not fully agree upon the definition of AMR technology. This is why we have become familiar with collaborative AMRs – or smaller robots – that can operate within inches of humans.ĪGVs are mobile robots that follow exact guide paths whether a physical or virtual “line.” AMRs are mobile robots that dynamically generate paths based on the current environment and the most efficient route between the AMR’s current location and future destinations. Indeed, many AMR vendors chose to forego ANSI B56.5 compliance altogether. However, its history as an AGV standard created ambiguity on its applicability to AMRs. Recent updates to ANSI B56.5 have recognized that current robotic systems can dynamically plan their path and do so safely. They can also navigate around obstacles or reroute to alternative paths instead of stopping for blockages. AMRs do not follow a strictly-defined path. However, with the advent of AMRs, a grey area emerged. With its AGV roots, B56.5 initially focused on making sure the AGV stopped if it deviated from the intended path, or encountered an obstacle.ī56.5 is a useful standard that still applies to a broad range of automated vehicles. Before R15.08, mobile robots applied ANSI B56.5-2019 (B56.5) as their safety standard across the board.ī56.5 was originally released in 1978 to address safety for AGVs. To understand the definitional importance of R15.08, it would be beneficial to review a brief history of the safety standards for AMRs and Automated Guided Vehicles (AGVs). R15.08 also provides clarity on the definition of an ‘AMR’, and differentiation between other mobile robot types, which is critical to the proper application of R15.08. Recently, the American National Standards Institute (ANSI) and Robotic Industries Association (RIA) have released a new safety standard – For Industrial Mobile Robots – Safety Requirements ANSI/RIA R15.08-1-2020 (R15.08) – that delineates safety standards for different types of mobile robotic systems, including AMRs. In turn, these same standards assist technology vendors to ensure that the solutions they develop follow universally accepted best practices for safety. Consensus safety standards must be in place so that industry can be assured that industrial mobile robots are safe. Autonomous Mobile Robots (AMRs) are a rapidly growing segment of industrial automation that have lacked universally accepted definitions and their own safety standards.
