Description
Okay, so it's not a real schematic...I just wanted to try to figure out just how an Extraterrestrial Vegetation Evaluator (E.V.E.) might work.
Surprisingly, no, I have not seen the movie "W.A.L.L.-E.", but I have read a bit about the characters online.
E.V.E. (c) Disney-Pixar Studios

Thanks. ^^
Would you believe that I made this over a month before I actually saw the movie? XD

No I would not believe that.
Just Kidding.

The free floating magnetic system allows for EXTREMELY FAST limb movement! If her arms and head were physically attached via a motor of some kind, there would be too much friction to allow her arms to move quick enough for her to do certain task.
There is one scene (I won't tell much about it to avoid spoiling the movie for you) where she is franticlly repairing Wall-E. She does this VERY FAST. Her arms moved so fast it was a blur.
Motors and servos would have slowed her down quite a bit. Plus this elimidates the threat of dust build up, since there is no moving joints to jam up.

I've seen the movie.
Yes I remember that scene. True, it may not be as fast, but there's less to go wrong, and the power requirements would be extremely lower.

EVE just wouldn't be the same if her limbs were physically attached though.
It looks so much better that way. Plus the arms and head are extremely easy to fix/replace since you don't have to unscrew anything to remove them. I still believe that the free floating design for moving parts is superior to mechanically attached limbs. But everyone is entitled to their opinion!
Not to mention that one of Apple Inc's designers was called upon during the design of EVE, so that is also a major factor.

Yes, I've heard that Apple Inc. was called upon to help with this movie. Not only EVE's design is based off of their tech, but if you listen in this one scene, When WALL-E's solar battery is fully charged, it makes the same noise that the new Linex-based Apple opporating system makes when the computer starts up.

Yes I am aware. But did you know that EVE also has a Macintosh startup chime? Its one from a modern Mac, but since I've never heard what the modern macs sound like when they startup, its hard to tell when the sound is presented in the movie.

Yes, I'm aware of that. Also, I know that one of the designers from Apple also worked on EVE's shape/configuration.
Although, I'm not really too fond of that fact, since I don't really like ANYTHING from Apple at all. >_<

Also as long as she enters "egg" mode (since the parts are attached to her body pretty strongly when in this mode) there is little chance of someone or something taking off with her blaster.
During the scene were Wall-E had the blaster, it was a result of interfering with a diagnostic machine that was working on her. She "allowed" the repair machine to take her arm away. But then Wall-E busted in thinking the machine was injuring her and stole the arm from the repair machine. So if she is unwilling, it would be next to impossible to remove one of her arms or head.

God I wish there was a edit function for comments!
One last thing to add. There is more then likely rather strong permanent magnets (you know the kind that don't need power..your fridge magnets for example) that pull the parts towards the body and keep them there, even if there was total power failure, the arms and head would remain attached to the body (and rather strongly too) When she is inactive, the electro magnets seperate the arms and head with enough force to keep the the limbs and such from accidentally sticking back onto the body from the permanent magnets. This is why her head and arms wouldn't just "fall off" if she suddenly lost all power. (which never happened in the movie by the way, she "turns off" a few times, but didn't loose power)
Well that should be the last thing that comes to my mind...for now lol

I can almost guarantee that EVE uses some sort of super-conductive material for the electro-magnetic systems. We are already in the early stages of developing technology to transfer power wirelessly (which is obviously needed for EVEs components to work properly) But we still haven't perfected room temperature super-conductors, so having a robot with limbs that aren't physically attached is a bit of a long stretch at the moment.
On the other hand, the head could merely be a camera and audio interface for the body. So she could run without the head, but could end up visually impaired and perhaps lose hearing ability as well. She could still use the scanner to navigate, but would be greatly hindered without the head unit. Not sure where her "speach" comes from since its impossible to tell if it comes from the head or from the body.
As for the blaster, it was shown to work when disconnected from EVE so it must have its own power source. I wouldn't be surprised if all the parts of her had its own power source. I suspect the bulk of her CPU and AI is located in the head portion of the probe and the body is merely a mode of transportation for her. (her head needs the body to float) Theoreticaly, her head could be removed from the rest of the system and and still function. But that depends on what systems they put in the body. Of coarse Disney will never go as far as to explain how a probe like that is supposed to work.
Also its not known how far the "communication" for the individual parts are. Though one the blaster was seperated (or simply moved away from here since its not physicaly part of her) she seemed to have lost control of it. So component communication and power transfer between each is limited to 1 foot or less. Same goes for the megnetic system. Though her fingers could be more limited since they don't need to seperate as far from the arm. (she has no "hand" to speak, just fingers)
Perhaps I could try a schemetic of my own. I can't draw very well so I don't think it would look accurete, but I do believe it would be more detailed as to possible system details. But it would only in the end be an opinion and would have no scientific bases for it. I do have a good knowlage on how computers and robotics work so it would be closer to what it "could" be if I were to do one. PM me if you interested on my "take" on how she would work in real life. My post here is already too big!

Unless each individual limb had its own power supply. I personally like the zero-point battery concept that already exists (it draws an unlimited ammount of power from an atom's nucleus, but only a small ammount of power as of late). I've heard about it on a few documentaries that I've seen a while back, and I like it as a power supply concept.
If you could amplify the energy of that battery, I think it would be efficiant enough to power all of EVE's componants.
Superconductors are an interesting idea, but if each unit had its own power supply, the would not be needed for transfering power and/or commands to the limbs, and I think that a regular short-range radio transmitter could handle all of the controls for each limb.
I'm no robotics expert (and am, admittedly, not very educated on the subject), but that's my theory on that. Besides all of that, I currently have no intention of building an Extraterrestrial Vegetation Evaluator probe.

Perhaps. No way of telling what future technology would turn out. There is technology out there that can send "power" wirelessly, so that can aswell go along side the individual power supplies. The reason I mentioned that each component has a seperat power supplie, is due to a certain scene in the movie.
At one point Wall-E has the separated arm and accidentally shoots it off WHILE it was separated from EVE. So either she can power the components from a considerably longer range then expected or the component has its own power source.
I doubt she was still powering it herself since she would have turned it off the moment Wall-E had contact with it, however she didn't, which suggests she no longer had control of the arm or the ability to power it up/down from her body. Unlike Wall-E, the movie never shows how EVE "recharges". So there is no way of really knowing how she is powered. Perhaps nuclear fusion or the type of power source you mentioned above. If it is via Nuclear fusion or similer, then the body recharges each part when its attached to the body. (when she is in "egg" mode as I would like to call it)
This would explain the need for her to "sleep" (as shown in the movie, she goes "inactive" for at night when on earth). She would "recharge" the arms and head during this state. Since the components might need to be closer and immobile inorder to send power to them correctly. This also to ensure the parts don't get to far from the body and "get lost".
Her body theoretically never needs recharging.
Also sending "commands" to the limbs is seperate then sending power to them. So even if she didn't have to send power to them. She still needs to send some sort of wireless data communication to the arms since there no physcal wires going to and from each part. As you can see she had fingers and can control them. This requires her to send data to the arm so that the arm can tell the fingers what to do. So we know for sure that she employs some sort of wireless data communication to each part.

True, that would explain why she'd need sleep mode.
I kinda feel that EVE's desing is somewhat impractical though. I mean, if the unit needs to stop functioning just to recharge its own limbs like that, wouldn't it just be simpler to have the limbs/head attached to the body by a servo motor? That would require no recharge time, no risk of the limbs 'getting lost' simply by motion, and no real chance of a misfire of the ion cannon.
If I were her designer, I definately wouldn't have the limbs 'attached' by a magnetic field. I'd probably use a servo-motor set-up, since it would use less energy, and there would be a lower chance of failure (and even if the motors did fail, the limbs wouldn't just fall off the unit, they'd merely shut down, and go into safe mode).

Hm, that design seems feasible. 700 years into the future means that Moore's law will yield some interesting results. xD
Anyways, I just saw Wallβ’E last night and I think it was one of the most adorable things ever. Highly recommended. ^^

Ah, so you're familiar with Moore's law too (I know about it, but I've forgotten the exact ratio of advancement to time). ^^
I just saw the movie today BTW. It was good. ^_^

Well if I recall correctly, it states that our computer technology will double in sophistication every 18 months.

I think I'll draw another pic. of E.V.E. sometime.
π: 0 β©: 1
Oooh, yes, please. Just remember that her arms are not perfect ovals. 
π: 0 β©: 0
That's what her name stands for? I didn't know that!
π: 0 β©: 1
According to what I've looked up online, yup, E.V.E. stands for Extraterrestrial Vegetation Evaluator .
π: 0 β©: 1
That explains why she was designed to scope out and retrieve plant life on Earth.
π: 0 β©: 1
Yup.
I guess she's a kind of scout probe.
π: 0 β©: 1
It also explains why there's more than one E.V.E. in the movie (they're inactive, though, when WALL-E saw them)
