Wifi Robot Spider for Crawl Spaces and Acoustical Ceilings

At Radio Shack you can pick up little remote control hex bots.  Some look like little crabs or spiders.  I have recently needed one of those little babies with a video feed and a little claw to grab (and potentially drag) a wire or debris.  You could use it to inspect crawl spaces (for all you home inspectors out there) or to run flex tube or wire through gaps too small and too long for human hands.
