We recreated the very first robot of Chernobyl Reactor Sarcophagus!

Another chapter of Chernobyl's history comes to light as we explore the half-mythical tale and successfully recreate the legendary toy robot of 1986! This makeshift machine was based on a toy rover, to which a radiation detector, vidicon camera, thermometer, and lights were attached. Back in 1986, it conducted primitive radiation and thermal surveys within the Sarcophagus of the destroyed Chernobyl Unit 4. Although its design was not as sophisticated as those which followed, in the early period after the Chernobyl disaster, even such solutions worked well.
The project was very challenging due to a lack of information and was completed through extensive research and component identification, relying on a written memory provided by physicist Oleksandr Borovoi and a few existing blurry images.

Thank you! Love you city!

[@chriswareham]

Utterly fascinating! I was a child in the United Kingdom during the Chernobyl disaster, and remember it vividly. Apart from your wonderfully dry humour, one of the things that made a big impression on me during this video was how factories like the one that produces ICBMs also produced toys. I have two electronic musical instruments from the Soviet era, Lell 22 keyboards, that were produced in a factory that usually made radio equipment for the military. Here in the West, "military grade" equipment was incredibly expensive, but almost always beautifully made and easy to repair. My Lell 22s are extremely badly made though. A friend who grew up in Soviet era Russia explained that at that time everything was made according to "norms", a system where each factory was supposed to produce a certain number of items each month or else the workers would receive less pay. This meant everything was made as quickly as possible, and not tested, with items made towards the end of the month being the worst quality.

[@ChernobylFamily]

True story about plans. And thank you for sharing yours!

[@mahekorvenoges550]

That is indeed a peculiarity of the soviet system where most factories were built exclusively for only military production. When the leadership decided it was finally right time to consider improving the living standards of ordinary people as well, they gave an order that _every_ military factory had to quickly find a consumer product and start to manufacture it (in addition to the military goods).

[@SonicBoone56]

That toy seems really well made, like stuff from America in the 1960s and 1970s. It's no wonder that the radiation team would use it as a base.

[@ChernobylFamily]

I believe it was more a spontaneous idea... at least Borovoi in his book describes it in a way that it gives this vibe.

[@SonicBoone56]

​@@ChernobylFamily sometimes genius requires quick thinking. Definitely don't blame the man for thinking of using it.

[@peepopalaber]

Fuck yes, great job on the replication of that simple but ingenious little robot! Maybe we get in the future more excursions into soviet robotics?

The chairs and flooring at the Museum in Kyiv integrating the appearance of the reactor is some fantastic design too!

[@ChernobylFamily]

Back in 1992, the entire museum was created as a solid art composition.

[@user-ms1ym9un2y]

I do recall learning about the original, at the time. As I remember it, a Channel 4 (here in the United Kingdom) television documentary crew went to Chernobyl. The researchers there were terribly poorly funded, hence their need to adapt a toy tank. The documentary showed them using it to explore the interior of the reactor, which (shockingly) was found to be empty: all the interior structure and fuel had melted and oozed out of the containment (most famously creating the so called "elephant's foot"). The Channel 4 documentary crew left behind their radiation suits, for the researchers, who'd only received ordinary chemical protection suits.

[@ChernobylFamily]

Yes, i remember that movie. The story is beautifully said, but they told what they were told by Kurchatov's expedition which likely wanted to gain attention and subsequently, foreign funds with was an issue in 1991 (the movie went on air around that time). The footage they used (which we also partly did) was manipulated. Specifically, in that documentary there were glued together a fragment with this robot and image of the reactor internals; the latter was clearly made with a PTZ camera like those we told about in our another video, the robot won't move this way to give that kind of picture. Not even speaking, this device never ever could survive even close to that place, the levels there were insane back then, that would burn away and plastic chassis melt. We had a chat with the Shelter researchers, they confirmed our guesses: it went relatively far, in outer corridors which nevertheless had severe radiation levels to be explored. Speaking about the Elephant foot, the way to it is not passable by any machine for 100% and before your reach it, you need to pass other, not less nasty FCMs. Summing it up, I mean, it DID it job, but not the way how it was presented, and myths were added over the years. That made the research of the project pretty complex. But very interesting.

[@ChernobylFamily]

[@3atsleeprepeat]

@@ChernobylFamily thank you so much, i was not expecting an answer so fast. It is crazy to think that they just modified a toy and sent it inside. When they talk about radiation destroying these "robots" it makes sense now. But then again, even modern NPP robots suffer from damage when surveying reactors that are not leaking or in malfunction. In my mind i always thought they were huge robots that were used - kzbin.info/www/bejne/Z4LTapePnLl3iqc - similar to these. It fills me with anguish that none of the "liquidators" or the families displaced from Pripyat were ever formally acknowledged/awarded/or compensated. They saved the world from disaster. sorry for the long reply.

[@Matt_The_Hugenot]

This little robot and all the other work that was done helped save so many lives all across Europe.

[@ChernobylFamily]

[@Damien.D]

Fantastic work on this project. The attention to detail and historical accuracy is impressive.... It's pretty strange that the engineers at the time had to do such a makeshift work, knowing that Lunokhod (in toy form at 5:00) happily drove on the harsh environment of the Moon close to 20 years before. Can't wait to come to see the exhibit and play with it ;)

[@ChernobylFamily]

Thank you! If you check Borovoi's book, he explains that there were attempts, but conditions were far more extreme than those designers imagined. As for Lunokhod, it actually happened, if you watched our documentary about robots released in July, there was STR-1 robot designed by A. Kemudzian who actually previously developed the Lunokhod and transitioned his idea to STR. But this work was very discoordinated, solutions were needed "for yesterday" hence there was a mess...

[@serhiityshchenko4006]

Great job as always! Thanks! BTW Is there any information on max range of original robot? I don't think it was more then 10 meters. If so, then robot was more like "round the corner" scout.

[@ChernobylFamily]

15 meters. You are right, Borivoi describes it as a 'scout dog'. But knowing the Shelter, I can confidently say that sometimes to have 'eyes' one meter away from you may save health. What this thing actually did.

[@UpLateGeek]

Your robot looks amazing! And it works surprisingly well considering how old the toy was. I can see why the Chernobyl engineers decided to use it in the first place. Anyway, great work! I can't wait to see what you're going to do next!

[@ChernobylFamily]

Thank you so much!

[@ptonpc]

I wonder if they ever gave the original a nickname? Thank you for recreating another bit of lost history. I do remember seeing video of the original years ago and even then it was just described as a modified toy. Slava Ukraini!

[@ChernobylFamily]

Borovoi describes it exclusively as "Little Toy Tank". He seems to be the only person who actually paid attention to it, names of all other participants were lost in the waves of history, and AFAIK, Borovoi passed away either last or this year (5 days ago we had a meeting in Chornobyl town, one of old colleagues mentioned that). We, however, this robot it "SI-6", which is acronym from Ukrainian "Blue Duct Tape, 6 Meters", as exactly that much of it went for this project. Glory to Heroes!

[@ChernobylFamily]

Thank you!

[@djohnsto2]

Wow this is amazing, I'm impressed by the realism. There may be a pot inside the camera controlling RF output gain that you can use to boost the signal before it goes through the coax. For the belt slipping on the driven rollers, you could try this stuff called "belt dressing". It's a bit sticky and helps with belt slip in car engines. That surplus electronics store was cool too - In Toronto we used to have a store called "Active Surplus" I spent hours in, but sadly it's been gone for many years.

[@ChernobylFamily]

About the belt dressing it is a very good idea. During a close-up inspection it is visible that motors do have enough power to move it well, but the contact between wheels and tracks is not that good as soon they get in their long-storage position.

[@edgeeffect]

That toy Lunokhod is very nice! I'm a big fan of Soviet space. The robot is a perfect example of a "hack" - combining ingenuity with whatever materials are available.

[@ChernobylFamily]

Still not the best. We showed this to engineers who design actual robots for the Shelter, they said that yes, this would work, but not that far. The only thing that can survive, must have all electronics at operators's place, and on the robot have to be only relays.

[@carpespasm]

True, voltage drop on thin wires for long runs would make it a bit anemic. I wonder if they fed it higher voltage at the control box to accomodate for that voltage drop when it met the motors.... @@ChernobylFamily

[@NathanielStauber]

It is certainly amusing to think what toys have been repurposed for serious work. Creative or unusual solutions to real problems are one of my favorite subjects. For instance, NASA used a tank chassis and electric drill while testing the space shuttle. It punctured the overheated tires so they wouldn't pop.

[@ChernobylFamily]

Thank you so much for your motivating words! Well, we had an extensive chat with the experts who design actual robots for the Sarcophagus; their opinion is that this thing actually had all the chances to work well due to the fact that everything except the camera electronics was placed remotely, and even this camera might survive some relatively high (not extreme, though) radiation. It surely did not go to, say, reactor core surroundings as some documentaries claim, but it could explore some outer corridors which already was a contribution to safety of people. Nevertheless, the project is complete but not over, we still will work on some enhancements to make it even more accurate before placing on a permanent exhibition. Glory to Heroes! Thank you!

I would love to see this robot get one or two more period appropriate upgrades. Such a small robot has incredibly high track area and motor torque so I would imagine the original robot was incredibly mobile with new tracks and motors. I've seen a few different methods for making model tracks. Maybe you could dig up the old Soviet recipe or you could try revitalising the existing tracks? I really want to see a part 2 of this video with the design at its full potential. It also lingers in my mind that someday the Chernobyl containment area will be fully dismantled and they will start unearthing all these artefacts.

The current day tech for similar tasks is the spot mini. And. Oh boy it's cool and does the reconnaissance with such a grace that this toy could never even dream of. The toy tank though, still does the same work. Less pretty and less agile. But still pulls it off. Yea i do appreciate the versatility of a walking robot. But for a simple task it's sometimes best to use a simple robot. And not having the tech of this decade did not hinder the ingenuity of emergency engineers back then.

​@@ChernobylFamily Знаю, але от я не бачив вживу такий, у моїх знайомих на початку 90их навіть програмованого луноходу не було ні у кого (Запоріжжя). То може для дітей партійної еліти вони були доступні хіба 🤣 Я вставив плату з китайської іграшки на 27МГц (TX2B та RX2B мікросхеми), модуль МП3, підсилювач класу D та пару АКБ 18650. Саме геморне було полірнути отой ковпак, бо він був дуже покоцаний.

Was the camera image actually sideways? as it is usually relatively easy to rotate the deflection coils and make the image appear the right way up.

[@ChernobylFamily]

They obviously rotated the coils; we followed the approach "works - do not touch", as it took 3+ weeks to get at least some functionality.

This Is So Awsome !

[@ChernobylFamily]

Thank you so much!

Just in time for Christmas

[@ChernobylFamily]

I'm happy about that!

[@sh-ig9fm]

Have you talked about the Chernobyl helicopter crash that happened you should do a video on that.

[@ChernobylFamily]

Well, that is pretty much well-studied story, but maybe in the future. It would be reasonable to add a surrounding context to it by explaining the works that have been performed at that moment.

[@volo870]

What a wonderful passion project! Boy, it must've been hell researching the device! I have A LOT of questions, I'll try to limit myself to the following: 1. How long do you think the control wire was? 2. Was the connector and robot body sturdy enough to evacuate the device by pulling its cord? 3. Do you think the wire had protection from interference? There was a lot if charges flying about... 4. Did you manage to fix image interference from the motors?

[@ChernobylFamily]

Feel free to ask LOT of questions, but let us answer to those four: 1. 15 meters as by Borovoi's book. 2. Yes. This in 75% cases is the plan. 3. That was a classical coaxial cable for video and multi-core for signals. There is no information on extra shielding. 4. Need to make a test if it actually occurs first.

[@volo870]

@@ChernobylFamily No.04 - Interference occurs. A 18:07 there is an interference line pattern when you push motor buttons.

[@ChernobylFamily]

@@volo870 Right. We will work on that.

[@nerd1000ify]

@@ChernobylFamily I think this interference is noise created by sparking of the commutators in the electric motors. I think it is probably authentic to the original robot, doesn't seem like something one would mess about trying to fix in the middle of an emergency so long as the robot was usable.

Amazing

Thank you! Cheers!

Soviet space toys are cool, i had one of those space rovers as a child

[@ChernobylFamily]

Thanks for sharing!

[@Mr.HaraldTheMan]

Alright now time to rebuild this.

[@ChernobylFamily]

:)

[@milksheihk]

I have a radio controlled(no cord) version of that same toy, but the control layout on this one doesn't make much sense.

[@TheAlexXxA1991]

First like, then watch. BTW Unis typewriter is from Yugoslavia (Unis Sarajevo). I never seen it in red colour, only orange.

[@ChernobylFamily]

A funny thing, we jever seen them in any color than red :)
