A power steering assembly and method of retrofitting therefore includes a housing having a cavity defined therein. The method includes heating the first and second elements to form an interface of material in a plasticized or melted state interface between the elements. A navigation image can be captured by the agent at the agent’s current location. The various measurements taken during the interval may then be used to calculate the flow rate. The system also has a widget interface that allows the user to add a widget to said design, specify a first state for the widget when the design is rendered according to the first dimension specification, and specify a second state for the widget when the design is rendered according to the second dimension specification. A second end of the steering arm is connected with the latch hook via a second rotary joint.
