      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.

    Why not drag a power/control cable behind it? The battery wouldn't be a limitation and if it gets stuck, give the cable a light tug. Also, you would lose a lot of weight from the battery. You could upgrade the motor to the gun turret allowing a greater range than "down" and "slightly less down"

      Just install a counterweight of some sort- put a mass behind the point of movement of the gun barrel which exerts a torque balancing the weight of the barrel+camera.Then you're only fighting the inertia of the setup, instead of the weight of the camera. Or you could just move the camera back on the gun barrel, although I suspect that you want it as far forward as possible, given the limited range of

    Obviously, now that we have recon covered we need to think about adding offensive capabilities. I mean, what good is it to identify all the major structural supports if you have no way to take them out? Robot Wars-esque saw blades are probably unsuited for implementation on the existing hardware base, even if external power could be supplied (viz. those "anemic motors"), so I'm thinking along the lines of a small thermal lance or incendiary package.

    Ever since seeing Home Alone 3, I've thought that something like this would be a lot of fun (it never occured to me that it'd have practical applications also).

    What would be even neater is if you could interface a computer with the remote and camera feed. You could, theoretically at least, take pictures of it's path through the house, and then write a small program to steer the vehicle around a pre-determined path, based on where in the cameras vision known objects are.

    From there it wouldn't be too big of a chore to have the program notify you, or react differently, when unknown objects come into view, or if it gets into unknown territory. Just think, your own sub $100 roving security system!

    Oh! And as for Home Alone 3... While it's by far not a great movie, it's actually pretty good, and is by far the best of the series (Yeah, I know that doesn't say much for it still...)
