Below are photos of my prototype Sentrybot that I assembled. It is currently controlled with an Arduino Mega and a Mini ITX. I'll be pulling the Arduino as soon as my EZ-B comes in. I've incorporated two digital CCD cameras that give stereo vision, digital range finder and GPS. Currently I have it set-up to navigate by detecting my wired dog fence.

This is my second project. It is not pretty, but it is functional. I am able to navigate this bot via WiFi. I used wiper and window motors along with a linear actuator for the arm. I am able to easily grasp and lift 80 pounds with it.

At least your cave is well protected :)

Is that a garbage bin ? How many batteries and amps ?

It is a recycle bin. I really liked its form factor.

12 and 24 volts / 5 to 10 amps and 15 amps respectively.

The taller bot (NOMAD) is 36 volts at 15 amps.

I use and modify cheap APC and Cyber Power uninterruptible power supplies. I get them cheap here in Michigan at Microcenter.

I love the Bin used as a cover.. I am trying to figure out how to mold fiberglass to make body panels. I don't have a 3d printer so I'm going to probably use fiber glass.
This is a pretty sick robot.

Great work ! I love the use of bin's as a form factor ! They're cheap, easy to modify and they look awesome !

Beep Boop, nice to see another security robot, ! would love to see more build details, wire schematic type stuff to compare notes, good job on keeping the build frugal on costs.
