Pictorial instructions for disassembling and reassembling an XV-11 can be found at the Homebrew Robotics Club wiki linked off of the page: Dave's XV-11 Notes. There are a few other XV-11 notes there as well, such as how to tap into the battery supply, and I'll be adding more as I go along. I'm too lazy to update two wiki's :) so I've decided to make the HBRC wiki my 'home' and cross-link from here to there and there to here.

Anyway, the disassembly/reassembly instructions were done because I kept forgetting where all the screws go. Hope it helps.
