The AGV Dynamic Weather Assist safety system increases the availability of automated guided vehicles (AGVs) in rain and snow. It consists of the outdoorScan3 safety laser scanner, the Flexi Soft safety controller and a software function block. Using the function block, the safety laser scanner automatically switches its protective fields depending on the weather, thereby enabling continuous operation of the AGV, even in strong rain or snowfall. Instead of stopping, the AGVs only move slowly than when the sun is shining. The benefits: Unplanned vehicle stops are weather-dependent interruptions of the material flow are avoided, and AGV mechanics and braking systems are protected.
