This guy needed to go underneath his house is a small crawlspace and decided to put a camera and some lights on a remote control tank instead of crawling down there himself.
After a few weeks, I thought back to completing my under house survey. 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.
This reminds me of the Pyramid Rover, the robot they used to explore a hidden passage in the Great Pyramid of Giza.
