The Crawlspace Tankcam

"I really wanted a way to look for under house leaks and stuff and, in the manner of a responsible home owner, get early warning so I could increase the effectiveness of... Ok, that's a lie. In reality, I wanted an excuse to put a camera on my R/C tank and drive it around scary tunnels, and this just happened to fit my purposes perfectly." Movies included!"
Like the bigger version of these Desktop R/C Mini-Rovers with optional wireless video cam?
The difference being the tank camera is mounted on the gun barrel and can be moved up and down, giving you a little more field of vision. The rotating turrent is nice as well since you can pan around without having to move the vehicle itself.
