  • Patent number: 10971386
    Abstract: A method for positioning a mobile device relative to a stationary device in a semiconductor manufacturing environment is disclosed. The method includes detecting a target affixed to the stationary device at a target location, wherein the target location corresponds to a location of the target relative to a reference point on the stationary device, determining a first position coordinate offset value based upon detecting the target, and moving the mobile device, using the first position coordinate offset value, relative to train the mobile device to move relative to the stationary device for the stationary device to performing a semiconductor manufacturing operation.
