How is open path navigation different from fixed path navigation?
“Fixed path navigation” commonly follows a guide wire or magnetic tape on the floor, using a pre-determined or “fixed” routing from point A to point B. Typically this is the same routing every time. Routing instructions usually come from a central computer and are downloaded, turn by turn to the AGV. If the AGV strays from the familiar paths marked with wires, transponders, etc., it becomes lost and disabled. “Open path navigation” ensures that any pathway to the destination is viable. There is no pre-determined routing from point A to B. Unlike fixed path navigation, open path navigation does not use wires, tape, or sensors. An “intended” route is calculated onboard by the AGV and remains dynamic during transport. That means the route can be changed and recalculated dynamically as required. ADAM’s use of open path navigation features laser scanners and gyroscopic motion sensors, while delivering high positioning accuracy.
