This is an autonomous cliff sensing gingerbread robot, commonly referred to as "Ginger." The Gingerbread was fabricated using a food network recipe, and the parts (excluding the wheels) were fabricated post cooking using a serrated knife and other assorted hand tools. The wheels were molded to accommodate their structural role. Brake lights engage when a cliff is sensed or when the robot is in reverse.
Midway through trials, some parts broke, but were fastened together with tape, and have not been repaired as of the publishing of this instructable (but will be soon, stay tuned). Un-taped final photos were not captured due to overwhelming robot excitement.
Not a house!? Try and convince my servos of that!
Just be prepared to meet the saddest servos on the planet if you do :-(

Thanks for looking!
