ASRS Vehicle

Overview and Key Concepts

The ASRS vehicle is a special type of transport specifically designed to work with racks. The ASRS vehicle will slide back and forth in an aisle between two racks picking up and dropping off flow items. The reach, lift, and travel motions are fully animated by the ASRS vehicle. The lift and travel motions will occur simultaneously, but the reach will only occur after the vehicle has come to a complete stop.

The ASRS vehicle is task executer. It implements offset travel by only travelling along its own x-axis. It travels until it is perpendicular with the destination location, lifting its platform as well. If the offset travel is for a load or unload task, then once the offsetting is finished, it will use the user-specified load/unload time to convey the flow item onto its platform, or off of its platform to the destination location.

The ASRS vehicle does not connect itself to a navigator by default. This means that travel tasks will not be performed. Instead, all traveling is done using offset travel.

In addition to the standard task executer fields, the ASRS vehicle has a modeler-defined lift speed and initial lift position for the its platform. The platform will return to this position whenever the ASRS vehicle is idle or is not doing offset travel.


Since the main distinction of an ASRS vehicle is that it only moves along its x and z axes and doesn't rotate, this object can be used for any purpose in which you don't want the object to turn, but rather just go forward and backward and up and down. In some models it has been used as a simple transfer car, or as a transfer conveyor between two or more conveyors.


The ASRS vehicle uses the standard events that are common to all task executers. See Task Executer Concepts - Events for an explanation of these events.


This object uses the task executer states. See Task Executer Concepts - States for more information.


The ASRS vehicle uses the standard statistics that are common to all task executers. See Task Executer Concepts - Statistics for an explanation of these statistics.
