I, Patrick, finished the proposal. I added to and revised the operation description so it now has the Google Earth integration for the GPS and the compass for the heading. The biggest obstacle the robot will face is the height of a curb, or six inches. I added the range to the specification list. I finalized the bill of materials by adding the 12V 15.5Ah lead acid battery, 4 amp battery charger, and the compass sensor. I removed the Arduino Mega 2560 from the BOM, since you said you have one we can use. I replaced the mechanical drawing and the electrical block diagram with the new ones from Matt.
Matt revised the mechanical drawing to reflect our most current design: no solar panels, two boards (Mega and Uno), one 12V battery, compass, and other minor changes. One potential change for stability will be adding a 6th cog on each side (top, middle). He also changed the electrical block diagram back to one battery using voltage regulators.
