Abstract
Systems and methods for controlling an overhead gantry crane are provided. One overhead gantry crane includes an X-axis drive motor, a Y-axis drive motor, and a hoist member operable to be moved into a plurality of positions by the X-axis drive motor and the Y-axis drive motor to move an object. The overhead gantry crane further includes a controller operable to control operation of the X-axis motor and the Y-axis motor and define a local axis coordinate system for the overhead gantry crane based on a reference point determined from an X-axis location and Y-axis location of the hoist member and a desired movement path for the object, as well as cause movement of the object by concurrently controlling the X-axis motor and the Y-axis motor using the local axis coordinate system.
