Abstract: A graphical system configuration program allows material handling systems to easily be defined, configured, and implemented. The system may utilize a computer for configuring an automatic guided vehicle system. Information defining the path layouts for the AGVs, traffic control information, decisional logic for path branches, update marker information, and other information useful for controlling the operation of the automatic guided vehicles may be entered into the computer and displayed graphically. The computer is programmed to automatically verify the validity of the entered information, and to optionally simulate the movement of the automatic guided vehicles. After the information has been validated, it can be converted to a file format that is used by an automatic guided vehicle controller to control the vehicle's movement. Virtually the entire design process for the AGV system can therefore be carried out using a single computer program specifically adapted for that purpose.

Abstract: A material handling system uses high-frequency location devices for determining the location of mobile units, such as AGVs, overhead mono-rails, conveyor components, or individual articles being transported by such units. The high-frequency location devices may also be used to identify the contents and/or routing information for material being moved within a facility. AGVs may incorporate the high-frequency location devices into their navigation systems to utilize the position and/or heading updates provided by the location devices in guiding the vehicle. The location devices work in cooperation with a number of stationary location devices, such as beacons, that are positioned within the environment at known locations, such as in or adjacent the ceiling of the workplace environment. High-frequency radars may also be used to provide electronic bumpers to the AGVs, allowing them to sense obstacles and take appropriate action to avoid collisions with the obstacles.
