Alternate Solution 3

Design #3 takes the same standard T shape as the other sailors with the intersection pointing toward the back.  The design is very lightweight, having only a single motor in the center behind the mast rather than having two motors controlling strings at the sides.  The frame is constructed from aluminum sheet metal with insulated copper wiring connecting the electronics, and will be 42 inches long by 30 inches wide.  It requires a battery system of two 9 volt batteries to power its single motor, receiver, and power steering.  The wheels are 90 mm urethane roller blade wheels with ball bearings.

            The design uses an entirely different mast positioning process than design #1 and #2.  The central motor turns the entire mast as opposed to the two string motors that only move the boom and sail.  This functionality opens up an even wider range of angles the mast can turn to, meaning sharper turns for the sailor.  When matched with the power steering and the right sail, this design will have broader steering capabilities, and minimalized friction when using the ball bearings will also improve performance.

            This design has less moving parts than the previous designs, meaning there is a smaller chance of something breaking.  Also, the design is very aerodynamic compared to the other two.  Its single front wheel help with sharper turns and the new flexibility in the mast’s turning radius. The design draws less power from the batteries with only one motor instead of two for controlling the sail.  Similar to design #2, there is a greater chance of this design tipping over during the second testing phase.
