A robot that, with a voice command, will use an arm to open a refridgerator and reach to a specified location to retrive a drink or something of the sort (bring me a drink, reaches to area one; bring me [a pizza], reaches to area two-- possibly multiple areas programmed), lower it down, place it on a tray and/or drink holder. Once the arm has set the item down, the arm will close the fridge door. Then the robot, with a digital blueprint of the building programmed and the controller wearing a trackable device, will bring the desired items to its controller.
