** More pics added 08/01/12 **
I spent the most of Saturday working on my Wall-E.
I did the typical carve out the bottom and added the servos.
Mounted the sonar.
For the arms I carved out slots for the mini servos. Screwed on the round servo horns. Then ground down the arm joints flat. Crazy glued them direct onto the servo horns.
I figured it's going to be a permanent install so I'm not too worried. I can always snap off and re-do if needed. The Mini servos seem to have enough juice to do the basic up/down.
I'll be adding a MP3 module with amp shortly.
The head seems to be the difficult part. Still working on a game plan for that.
Didn't take a whole lot of pictures but will take some more when I tear him down again.

As Requested, some close up pics of my version of head mount. I still need to fill, finish sand and touch up the paint.
Wall-E at rest. I like the natural head tilt. Because his head is only attached on one side this causes the head to droop.
Here is the neck. I did some extensive sanding down. This allows for clearance of the up/down movement. Glued a piece of styrene on top and shaped in. In the center is a 4-40 nut for the mounting screw.
Just another angle.
Here is the re-cycled Wall-E part mounted to the servo. servo horn is screwed on and crazy glued to prevent movement.
Another angle.
Servo fits perfectly in the eye. Hot glued. Only had to expand the existing opening slightly to accept the servo a head.
There ya be.

Finally got some of my electronics finalized for mounting positions within Wall-E.
Here we have :
All mounted. I just have to finish up the wiring harness for the MP3 module.
Just need to loom up the head wires and add a permanent battery pack and he's good to go.
That's really neat, i still need to hook my MP3 module up, still testing using ARC soundboard. Mine is a mess though, too many inputs. I'm going to run a 3000mah 7.4v Lipo, what are you using?
I've been looking at batteries as of late.
Not sure if I'm ready for LiPo. I keep hearing horror stories.
I carved out the back panel of Wall-E tonight. That should give me a better idea of size to cram in there.
I'll see. I need to look at batteries for (2) Wall-E's (1) Hasbro R2 and (3) Omnibots.
So I'm going to need a good multi-charger too.
