Hi check out what I found in the dumpster and it has not been widerized to prevent the Uh robot. Uprising and uh I can't risk having this thing become self-aware in the dumpster. We're going to tear this thing down so that uh Skynet AKA Samsung can't uh go Rogue on us model Sr 8980 running Windows CE Core 5.0 Thank you very much. Yeah, one of these uh robot cleanery things let us know if you actually use one of these things.

So it's got like spinny spinny things here. It's got really really things here that spin and these are these rubber Wheels They actually found they feel very compliant actually. I'm really liking the spring in that, but uh yeah. so we've got the bristles here.

It um, sucks it up. We just got a little non-driven wheel at the back there secret oh secret hidden on our switch. look does it actually do anything? oh I don't know I'm doing. it's okay I've got the wider Isa standing by.

Nope. And it's got two charging pads here. so I guess it goes back to base unit and uh, charges up three things probably. There's there's a window there is that is that infrared? Um yeah, it's got all Center I don't know sensory things I Got no idea.

Um, it does actually have a spy camera on top because it's got to uh, watch. uh. the humans is uh, here's the little uh, dust, um containment thing. It's not very big, but uh, it's got a filter in there.

None of that. uh HEPA rubbish. Is that a No. I thought that was some sort of micro switchy thing and um, yeah, so it sucks it in through here.

Um, so the pump will be up in there somewhere. It's got some rubber baby buggy bumpers around here, Is it? Yeah, it's kind of rubbery. Tear it down so it can't become self-aware Let's gut this sucker. So yes, don't just throw these out in the dumpster without wider eyes in them first because Sarah Connors Getting pretty old these days.

Can't count on her and you can't count on the future. So we've got to do what we can Here and Now to stop the uprising. I've planned ahead I Do own a bunker, so that's going to help. Highly recommended.

Don't leave these things to breed and become self-aware And don't be fooled by their innocent appearance and functionality. Let's have a look. Ah, there you go. There's the battery.

It's got two connections there 31.7 Watt hours. and you can't just rely on taking out the batteries either to stop the robots. You don't know what sort of hidden power source they've got in them. Interestingly, that pack looks openable.

might try that later. It's got a USB port down there for the Skynet update. I'll tell you what the cyberdyne division of Samsung have really built this like a brick. Dunny, It's not going to come apart without a fight.

Got this interesting looking rubber plugs here? Is that some sort of thing holding this in? Because I can't get this? uh, played out I Wonder if the rubber baby buggy bumper just comes off? Oh yeah, looks like it might. Well, it deserved it that had a flat Flex in it? What was under there? That's really interesting? What is that? that's not? Neither of those are a transparent window front rubber baby buggy bumper that just comes off I don't know. some heat studs or something? There you go. that's a human detector strip right around there.

I I don't know I might have to get those under the microscope. Yeah, they're obviously. uh, not. uh.

visual because you're not going to penetrate the rubber there. No. I did manage to leave her out. What are the wheels? That's your motor? Check that out.

Isn't that groovy? I'm going to keep that mechanism. that's that's really neat. Got to be able to do something with that. Have a fun project with that and exactly the same on the other side there.

Yeah. Interesting. uh. split.

Arrangement Like that. obviously a reduction gear mechanism in there. Yeah, that's obviously an encoder wheel. I Think there's going to be two magnets either side and then Hall sensors either side there.

I'm not sure if that's a user. uh, like replaceable and cleanable. but uh yeah, you can certainly certainly do it and more screws. Here we go.

I Still don't trust it I've got my uh, widerizer ready at the ready. You never know when it's gonna come back. Oh another. they love using these uh PCB interconnects like that.

Beautiful custom moldings and then they just slip in there and screw it in with the board to board. interconnects. No wiring. so there we go.

They got a belt in there. motor is going to be in here. Yeah, that is a PCB Mount motor there. You can see the tabs either side and another one of those are encoding wheels on top as well.

so it looks like we're going to score a uh a few decent Motors out of this puppy. this is gonna yeah. it slides off. Look at that.

I uh transparent that looks IR transparent? Yeah, you betcha. So these are Optical pointing inwards. Oh, is that a detection like a dust? So either that's a photo transmitter and receiver over here to detect that your plugged in the thing this or it's a white. Yeah, yeah, it actually goes through.

No, that's a dust. uh. way like a full sensor to detect. Um yeah.

so if light can get through, then it's obviously not full. If it can't get through, then it's full. So then it probably, uh, talks to your uh, spy shoe phone. does it? Is that a little programming header or something like that so you can access that from in that from you know, without having to take it apart I Suspect that might be a little pin which goes through there.

it might be a micro switch in there, so that's that. You've actually, uh, plugged it in. We do have an infrared receiver on either side, or is it a transceiver and that's where it makes cute little beep beep noises to make you fond of eyes. And it's so cute.

and uh, yeah, hide, its real reason for existence. That little uh five sensor array there does seem to be separate from this one here. So yeah, they're both buggering off into there. So I don't know why you'd have an extra little strip there and that looks to be an optical infrared window.

that's for the brush that goes around there. so there's one on either side. So maybe that detects that the brushes. or maybe it detects dirt.

or I don't know, a brush rotation and you can lever up these plastic strips here. Way there we go. Uh-huh Oh yeah, Oh yeah, we're in. Look at that cyberdyne.

Systems Technology That's a first they've used RFI uh, conductive sponge there as the touch. uh, contacts. That's interesting. Um, that's a nice reuse of a component that's normally used for, you know, shield into outside enclosures now.

I did find out who actually uh, developed this and I'll put a photo up here and um, yeah. well. I'm I'm off to his house right now. So there you have it.

There's the guts of this thing. Maybe you can't see that, but I can actually spin the um impeller I didn't even see where it took the air from, Didn't see any vents on them. don't recall seen any events on this thing. Got a bit of rust down there and there you go.

I was right about that micro switch so that detects when you uh, plug in the container on the front presumably and infrared transceiver. It's got It's a four wire jobby got one on both sides there and that's just an interface board is it? And more sensors? There you go. There's another one there and they've got a like a stereo unit there there and there at different angles. Uh, so that'd be matching on the other side, would it? Yeah, of course it is.

There you go. and I don't know. Does this thing come with a remote? infrared remote control? Is that our Cyberdyne processor there? Oh no. Hang on.

there's the Cyberdyne Systems module there. it is. Ah, they can't hide it. So Tele chips.

That's just a front company for Cyberdyne Systems who is a, uh, wholly owned, uh, subsidiary of the conglomerate of uh Samsung and the uh World economic. Forum Like everyone knows this like it's not a conspiracy at all. And there you go. There's those three touch sensors just uh, conductive adhesived those down to the PCB down there.

and um, yeah, they're the three. That's how they extend the touch sensors. I I Love that reuse there that is fantastic. So there you go.

There's one of our two uh motors for those little, uh, brush spinner things there. They're not a direct, uh connection. it goes through some sort of reduction. uh, gear mechanism.

Aha, that thing on the top that's actually a lead. There you go. It's just a lead indicator. More of those, um, infrared transceivers there.

Another Joby here. Maybe that's for external comms or something. that's you know it's probably not a user. uh thing.

there's there's just got the uh, that's just that swivel uh wheel. There doesn't do anything. It's not powered, it just swivels around our main processor there. that's an Nxp jobby.

and there's our little camera module on its own board. There little castellated edges just, uh, you know, a Reflow soldered onto there. So yeah, a tiny little module. I Don't know.

That's probably one of those little Sony sensors they own most of the market. They're all part of the conglomerate, so they're the main boards in this thing. Got our main processor board here? These two are motor. Drive Board: You can tell because they're physically connected over to the motors and uh, they've got some powery type devices under there.

Does that? SMD There does that one have a uh, yeah, there we go. There's some power stuff on the bottom there, so that's for the bigger motor drive then our sensor board here. and well, we can have a look. where are you? What's that? What's that special? Cyberdynes can micro Infiniti Cruise core.

Interesting. Anyway, you can see the huge sensor array all the way around that Now Interestingly, this Rusty bit we've got over here. This is just a weight. It's a weight to balance out because on this side we've got the motor for the brushes and that's got a certain weight and then that's going to like imbalance.

Uh, the weight profile of this thing. So they need to balance. You know, balance it all out. So they've calculated what size weight they need like steel weight and they've whacked that in there.

It doesn't matter if it rust of course. Um, yeah, you just need to balance it out. so that's nice. attention to detail and probably necessary.

Um, from an like a positional accuracy? uh, point of view because you can't. you can't have like an imbalance star robot and try and drive it around the uh, the inbuilter inertial measurement unit that we'll take a look at. Um, you know internal gyroscope needs to know where it is and if you you know if it's unbalanced and things aren't going right, all your little errors can like accumulate over time and it can eventually well not get back to its uh charging pod and well oh sad face. um it's just going to run out of battery and it's just gonna help.

Maybe it beeps and there's little voices I think is hell. pick me up Judge Me Love Me says there's your impeller vacuum uh motor there and that's just done mounted on a compliant rubber baby buggy bumper there so you know it minimizes our vibration. Everything else but yeah. I don't know where the air? I mean you know? I've got some vents on the back of the that battery compartment was sealed.

so yeah. I don't know. Yeah, it gets in somewhere. it's all dust is all accumulated in there.

Lovely, of course. Uh, the filter in the Uh element tries to keep that out, but you know stuff's eventually going to get in there. And for all you will drive aficionados, there you go. That's the mountain plate for it.

Got a reduction gear train in there and there's our spring that was, well, was in there somehow. that was, uh, it felt really nice and uh, balanced. It was, uh, quite well done. and can we get that out for you motor aficionados made in? China Come on.

Samsung South Korea Where'd you guys show some national pride? You kidding me? In the exact same motor there is used in the uh, brush, uh, driver either side? So yeah, we've got four of those jobbies and this down here is one of the cliff sensors and that will uh, detect whether or not it's going? Uh, whether or not there's a floor. Is that some sort of looks like a you know, like a little hall effect jobby? But ah no. sorry. I Thought that was the cliff sensor.

The cliff sensors in here. and there's another one over here like this. So obviously that board is doing some sort of uh, magnetic, uh sensing? Um I Don't know what? Um, maybe, uh, like a homing thing once it gets on the charge pad or something like that to know it's in the right spot. perhaps? All right, let's take a look at these uh bumper sensors that are along the front.

You can see that they're little green dots there. they're all in parallel and I measured the capacitance of these. and uh, they're only, you know, tens of puff. So that's just the trace capacitance basically.

So they look like their membrane. um, touch sensors. You can actually peel one away there. you can see inside that? Yeah, we just got uh, two carbon pads there.

two conductive pads. So because they're not like a, uh, take, they're not tactile on dome, it's just a membrane switch array. So yeah, it's just they make contact and and that's it. So they're just an array of parallel membrane switches.

But they're You know, they're awfully small for the job. You can see that this this strip in here is the one that I think pushes against these. So if they've you know if the uh robot hits any object, it deforms that and it's going to at least depress one of these. Hopefully that's the idea, that's why they're all around that front sensor like that.

So they're probably just manufacture them so they're a slight bit apart and it doesn't take much pressure I guess to activate them and and press them. but there. Yeah, there you go. It's just a membrane switch.

Doesn't need to be any more complicated than that. No worries. And if we have a squeeze at that Uh Cruise core from a company called Micro Infinity dates from March 2013, so you know it's near on a decade old now. Apparently this Um Samsung unit is like a top of the line unit it was back in the day way.

This tells us Uh is a digital gyroscope and accelerometer used for measuring angular rates, heading angle, orientation, and urine accelerations under Dynamic conditions. Highly compact light, fully self-contained Uh device internally contains a Mems gyroscope, a 3-axis accelerometer internal volt because a gyroscope is different to an accelerometer, and inertial gyroscope is what you actually want to get back to. Like know it's like a starting location on the charging pad, go around autonomously and then make its way back. but you can't just do that.

Hence why it has the cameras. it's I believe it's got like a that's why the camera points up because it can see the ceiling and you can get like the corners that can build up a map and it knows you know it can roughly knows where it is that Uh prevents it from going on a complete Walkabout Um and not getting back there. so it's got uh yeah, Signal Processing, ad Converter, Wrist Micro, patented error corrected algorithm, and adaptive reduced order Kelman filter reduce the errors that affect the this type of system: bias, drift, Scale Factor Symmetry As a result it produces well that usually a Kalman filter. they would use those in like modern autonomous cars and stuff like that to actually predict what objects are going to do, what objects in front of them are going to do and stuff like that.

but they are saying it reduces errors that affect bias drift, Scale Factor Symmetry stuff. So I guess they're using it differently there. Interesting. Um, it takes a second boot up time to compute bias parameters and stuff like that does not require calibration after that.

So there you go. It's an all-in-one unit so if you find these in the dumpster, you've got a very cool I Don't know how much this Uh chip costs or a modern equivalent cost, but you know that's a it could be a very fun thing to play with block diagram here. So the sensors and AD signal processing in the Kalman filter that or error correction filter so that all um yeah, it's not actually doesn't seem to be be predicting where object, what objects are going to do moving objects because I guess there's only humans and pets and stuff walking around. It's not too busy unlike an autonomous car which has everything including like light poles just jump out at you.

There you go. Very simple. It's just got a nice squared C and A SBI interface. Geez, that might be interesting I wonder if you could see anything if you took if you de-canned it? I'm going to do that in this video, but leave it in the comments down below If you want me to try and somehow get the can off that sucker, this is a very limited application.

Note: I'm sure you can get more from them if you're uh, yeah, if you're Samsung But there you go. that's inside and older. Um, top of the line. Samsung Robotic vacuum cleaner thingy.

uh, most interesting, you know, spared no expense. they haven't really. Penny Pinched. Although, that main Nxp processor we saw there that would be doing uh, like that'd be connecting to the camera and doing all that sort of thing so well you know it's a Samsung value.

Add a higher. lots of higher order uh stuff and things like that. Northern mapping you know I Saw the ceiling mapping and other roof mapping algorithms, but this is the heart of it. This uh, Cruise core thing which contains the gyroscope and the accelerometer and Cowman filter and all that sort of magic.

Anyway, it's interesting and yeah, if you find these in the dumpsters, you can get some cool uh sensors and um, like gyroscopes and and oh, and motors and all sorts of things in this to have a play around with. Just put them in your jump in and I don't know, pack something very neat with these kind of things. So anyway, I hope you enjoyed that dumpster diving tear down. If you did, please give it a big thumbs up.

As always, discuss down below and yes, Do Not throw these out. Widerize them or tear them down before you throw them out. We don't want them uprising catch you next time.
