Price Estimates for Prototype

At this time building a complete prototype is not necessary.  For this reason a few systems were selected to be prototyped.  These systems will be built to test the design that will be proposed.  The systems chosen are as follows:

        1) Obstacle Detection (i.e. Image Processing)
        2) Drive and Steering Assembly
        3) Thermal System


Cost Estimates for each system


        Obstacle Detection 

        Option  A.      (1) B&W Camera          $200.00
                        (1) Frame Grabber       $800.00
                                                $1000.00

        Option  B.      (2) B&W Cameras $400.00
                        (1) Frame Grabber       $800.00
                        (1) Video Mux.          $300.00
                                                $1500.00


        Drive and Steering Assembly
                
                Drive Motor                     $150.00
                Steering Motor          Approx. $100.00
                Materials                       $50.00
                Electronics                     $100.00
                                                $400.00

        Thermal System

                Peltier Device                  $40.00
                Graphite Epoxy                  $30.00
                PPS body material               $30.00
                Gap Pad Insulation              $0.00
                                                $100.00

If budget permits, a scaled down mockup would could be built with the following :

        Simple frame                            $50.00
        CPU controller                          $1200.00
        Camera Option B                         $1500.00
        Power Elec.                             $100.00
        Steering & Drive Motor                  $150.00
        Motor Elec.                             $200.00
                                                $3200.00
Note: This Budget would also included the Drive and Steering Assembly and the Thermal System for a total of $3700.00.
