The Pet Care Robot (concept) is a Wi-Fi controlled bot that can serve as your remote eyes and ears from a web interface. But what’s a bit different than a Rovio is that this robot allows you to play fetch through a remote-controlled ball you can steer around the house—all while nurturing your animal through a built-in speaker in the robot’s base.

Also of note, the Pet Care Robot has two large eyes that any dog will love to chew into a slobbery gum. (Those protective eyelids, though good in theory, are a lot less durable than rawhide, shoes or the rest of the items your pet will be munching on while you’re away.)

Still, there are times I’d like to check in on my little hellcat when I’m out for an evening. And if I had a tool to torment her at the same time, all the better. [MintPass via Geeky Gadgets via DVICE]

Beyond the urban camo paint job, the Rovio was loaded with a remote control fire extinguisher and equipped with some software tweaks that allow the robot to spot fire (and subsequently annihilate it) autonomously.

Remember that scene in Iron Man when the robot kept dousing Tony Stark with the extinguisher at comedically appropriate times? That’s what you can expect from this Rovio…which sounds pretty fantastic. [Robots Rule via SlashGear]

Keep in mind, though two of these list for $US400, most cap at $US250, and they’re all toys. They don’t have a heck of a lot of AI, though they do have an impressive array of user-triggered functionality and some goofy “spontaneous” behaviour. You ain’t getting C-3PO no matter where you turn, not even R2-D2, but there’s something cool about each of these:

Mr. Personality – $US245
This is one weird bot. Turn it on and it will act like one of the many “personalities” you have downloaded to it, telling jokes, reading fortunes and interacting with you along the way.
Pros: 3-legged, multi-directional wheels move in all directions easily; multiple personalities technically mean relief from boredom; depending on the personality, it’ll call you “master”
Cons: The default personality is very annoying; not enough functions to stay entertaining; obstacle sensors are too sensitive
Worth the money? Doubtful. Depending on the power of the development community some fun personalities may emerge, but they are severely limited by the options on the remote.

Rovio – $US240
Maybe the most technical bot of the bunch, the Rovio is a webcam-on-wheels controlled via an internet interface. With some smart manoeuvring, you can snoop on your daughter’s date in the living room from the privacy of your bedroom. Or, if you have your own domain server, you can control the Rovio from anywhere in the world. It has major limitations, like an awful camera and outside of Internet Explorer you can’t hear any sound, but its API allows customisation so there’s true potential that has yet to be reached.
Pros: Good looking, highly interactive UI; like Roomba, can return to its base to charge itself when batteries run low
Cons: Seriously shitty webcam; setting it up on a Mac is torture; if you bought this thinking you can easily control it from anywhere in the world for free you’re SOL
Worth the money? Not yet. The Rovio is a great concept, but you’ll be much better off waiting for version 2.0… or maybe 3.0.

Femisapien – $US50
She’s the female companion to Robosapien, and she’ll blow you kisses, dance to music or speak in her very own gibberish language with you. She doesn’t do anything very fancy, but she’s the only girl here, so she looks better doing it than most of these other bots.
Pros: Fairly interactive; relatively inexpensive; giant robot boobs
Cons: Command system very complicated; routines aren’t all that exciting
Worth the money? Only if your name is Zoltan.

iDance WALL-E – $US53
The cheapest WALL-E of the crop, and a less expensive alternative to the Rolly, iDance WALL-E dances—if you can call it that—to the beat of your MP3 player, or his own built in sound bank. A one-trick pony, but I’ll be damned if it isn’t an adorable trick.
Pros: Look at that little bot—how could you not love it? His dancing is fun and silly, and he couldn’t be any easier to use
Cons: The speaker sucks; WALL-E’s moves don’t match the music closely like Rolly’s do
Worth the money? When we first saw the iDance WALL-E, he was only supposed to cost $US25 bucks. But now, at twice the price, it’s definitely one bot we can live without.

Ultimate WALL-E – $US400
The name says it all: The biggest WALL-E of the litter is ultimate in every way. It will follow you around, dance to your music, or perform a pre-programmed series of movements and noises. Best of all, it uses a really interesting controller that can move WALL-E using a touchpad.
Pros: Big enough to seem realistic; a ton of features so it won’t bore quickly
Cons: Expensive; controller has too many buttons that don’t do very much; did I mention “expensive”?
Worth the money? Who has that kind of money to spend on a robot? Especially one that isn’t programmable, upgradable or all that intelligent. It should’ve stayed at its original $US190 price.

U-Command WALL-E – $US130
U-Command WALL-E is the Baby Bear of the WALL-E bunch, just right in almost every way. Its controls are comparable to the Ultimate WALL-E, it can move, dance and make noises on your command, all for a much more attractive price.
Pros: Essentially a “lite” version of the Ultimate WALL-E for less than half the price, versatile controls allow for repeated play without getting too stale
Cons: The only WALL-E without a line-in speaker for MP3s; not as technically impressive as other over-$US100 contenders
Worth the money? Totally. Even at $US130, it’s one of the cheaper robots on the list, and the most fun right out of the box.

Sony Rolly – $US400
At first glance, the Rolly doesn’t fit the traditional robot mold. The egg-shaped MP3 speaker looks like it’s just another smooth white gadget with an “i” in front of its name. But when you see it in action, it’s one of the most exciting little toys around, dancing wildly and putting on a light show to the rhythm of the songs coming from its body.
Pros: Great speaker; customises dance/light shows to your own songs; amusing even after repeated viewings
Cons: Can’t customise songs on a Mac (but you can on a Vaio!); can’t jump to a specific track on the device
Worth the money? Surprisingly, it might well be. I can’t put my finger on it exactly, but I get a huge kick out of the Rolly. The fluidity and snazziness of the movement and lights explains the steep cost.

D-Rex – $US150
The scariest bot of the lot, D-Rex growls, attacks and lets out the sounds of bodily functions from every orifice. Rubbery, lizard-like skin and huge, moving yellow eyes add to the effect.
Pros: Creepy; fun to play with (for a while); the coolest looking of all the robots
Cons: Doesn’t do too enough; may scare little kids (or is that a “pro”?)
Worth the money? Tough call. D-Rex is probably the biggest robot here and isn’t that expensive for being so big. But since it only performs a few functions, don’t expect anything close
to a Pleo.

Elmo Live – $US60
What’s left to say about the newest version of every kid’s favourite fuzzy friend? It raps, dances and tells stories and jokes, all in the body of the most popular Muppet of a generation.
Pros: Buy this for your kids and they will love you forever.
Cons: Don’t buy this for your kids and they will hate you forever; also, the song “Elmo’s Gotta Get On Up” has been stuck in my head for damn near six months
Worth the money? Do you have a choice? At $US60 it’s a steal compared to most of these other bots… but good luck finding it.

And now…
The Winner: U-Command WALL-E. One of the few bots here that is fun to play with more than once, this WALL-E is cute, interactive and kids can enjoy him without driving parents crazy by playing the same thing over and over—*cough*Elmo Live*cough*.

Runner-Up: Rolly. I can’t stop looking at this little dude. His syncopated dancing demands attention from anyone who sees him, and he is the bot that performs his most essential function—playing music through a speaker—the best.

Honorable Mention: iDance WALL-E and Ultimate WALL-E. I like you both a lot, but why did you get me all excited with your decent prices, and then double them when I wasn’t looking? Not cool guys.

The Loser: Rovio. No offence here Rovio, we really like the though of a remote controlled, customizable webcam and we think you will get it right one day, but right now you cost too much and the most important feature you have—your webcam—is absolutely terrible.

I like the way it finds its way back to the charging base automatically…though you’d better plan ahead on having it charged up if you want to use it for a serious business video conference. Though I reckon your colleagues’d be too amused by the strangeness of nattering to a robot for the conference to go smoothly…and if they’re Red Dwarf fans then the similarity to the scutters will have them giggling far too much.

The Rovio’s out this friday for $US300. [RobotsRule]
