Electronic MOD for the Walmart Robby. make the mouth flash like the movie.

[@DougCurtis_plus]

Thanks for the information John, I just completed the electrical, interior dome painting and the voice tube painting and blue gel mods. It came out great. The only additional thing I did was to 3D print a replacement button for the voice activation, on the front of that button I added a small brass cap with 4 holes, to make it look more like the original.

[@sammcdonald769]

Just absolute genius work on the video. 👏🏻👏🏻👏🏻👏🏻👏🏻 Anyway of increasing the memory storage capacity for the audio for the voice ? 🤔 Having a complete audio track for every conversation from the original movie will be amazing. 😆

[@Robothut]

No it is a COD "chip On Board" the black blob thing. All the audio and control electronics in one blob.

[@DalekBill]

Great help John, thank you. The model I have didn't have two black wires to move, one was black the other red, but your description and pics made it pretty simple.

[@Robothut]

Yes they seem to use any color wire that they have laying around, but they still do the same things and can be figured out. So glad it helped.

[@wurly1100]

Mouth flash mod was a breeze with your helpful video, Thanks!

[@lieutenantmiller2039]

Well - I thought I was a pretty good robot surgeon when I fixed my Remco Lost in Space robot. It was just a loose wire on the Kayko motor and replacing a blinker bulb from a jack-o lantern flashlight.It’s impressive that you figured out how to correct this!

[@Robothut]

I did electronic circuit design for a major corp. for 20 years.

[@Zathras01]

not many of us have 3D PRINTING capability to print our own tools....So I got those beam things off another way...In addition, I just painted the inside of the plastic in the speaker area translucent blue..I have no idea where to get a "gel"..looks just like blue plastic to me...your circuit changes went well. for me..thanks.

[@glorbusborbus480]

how did you get them off another way?

[@kevinsparks5955]

What is blue gel ?

[@kevingraham8119]

Hi thank you so much for the much-needed info you did a fantastic job covering this material videos excellent clarity as well as your instructions thank you again

[@Robothut]

So glad it was helpful for you.

[@kenlydiard6385]

Thank you for this video 👍 your video is so easy to follow, the mod work will be done to mine, makes Robby so much better, very happy viewer here, keep up the good work, many thanks 😊😊😊😁

[@Robothut]

Cool. Glad I could help. I have heard from many that have done the ratchet food fix so the robot walks right, but few that have done the electronic mouth action mod. I have done 4 full mods so far. What a great robot toy for the money !

[@kenlydiard6385]

Robothut Robothut I agree, for the money it’s an excellent buy, I bought an extra one, just incase I messed up on the electronics of the first one lol was so cheap I thought hey, why not ... well what a success 😊 followed your advice, and it’s excellent, I love what you did and very grateful for your vid, one very happy collector here, thanks buddy, a great post from you 😁😁👏👏👏

[@robfriedman3361]

I just got one from Amazon, as Walmart had none (though I did get a credit..so it's still $20) But, how do you get to the electronics? Are they in the torso? Personally, I would love to make 'walking' as an option, and always have the 'gyros' rotating when he is pressed. Maybe just the head moving as in the film. Oh..what gel did you use? Is there anyway to could either do a single video..from opening, soldering, and closeing up? Or a series of still photos?? I also have a trendmasters B9..and I always wanted him to say 'my sensors detect an intruder present' while in surveillance mode, vs 'Danger, Will Robinson.......' It just made more sense

[@Robothut]

I did 4 videos on this. you can find them in my Robothut channel. here is the one on fixing the walking problem for example. kzbin.info/www/bejne/nJ6rYWmjf8uNd7s There is only 1 motor inside so if you want the gyros to spin but the robot not to walk you will have to add a micro gear motor for that function. The robot already has a switch to turn off the walking action, so it is a option. I uised a blue lighting jell, but you can use translucent blue paint from a hobby store to tint the LEDS. I did a complete post of pictures and videos and information on the Alpohadrome web site. Here is a link for the topic. alphadrome.net/forums/topic/22906-goldlock-walmart-2020-robby-and-trendmaster-1999-robby-inside-look/

[@dennisstahl1183]

I just did a lot of masking (painters tape, a plastic shopping bag & a piece of saran wrap) & then painted the mouth with 3 coats of the Tamaya blue. Looks great! Is the circuit board for rewiring the flashing inside the torso, so the head wouldn't have to be removed? Thanks

[@shanerussell7335]

Yes! Exactly what I was looking for.

[@KarlTate]

Thanks for these videos, John!

[@matthewdavies2057]

Hope some tinkerer comes up with an add on sound board with more Robby sayings.

[@Robothut]

You could add a new sound chip with your own audio. But it is a lot of work.

[@jamestaylor2607]

Was wondering if you could make a video of how to wire in a USB power supply so the robot lights could be on for display without the talking or walking?

[@Robothut]

Seams like all you would have to do is add a KILL switch for the Motor and speaker. The robot runs on 6 volts "4 batteries at 1.5 volts each" so the 5 volts you get from the USB would be close enough to replace the battery power.

[@bobbova8708]

A huge thank you for sharing this info.The mods really make Robby pop! Also a shout out thanks to Boyd at trekworks for giving us a heads up on you're wonderful channel.,I do have a question and maybe you are one of the few people who might be able to answer it. On the old 1997 trend masters classic lost in space robot with lights and sound do you happen to know if any one has wiring diagrams or pics of the wiring and or boards inside?I had one damaged in moving and have no idea where the wires go inside.Any way thanks for this wonderful video!!!

[@Robothut]

So glad you found my channel. You will find lots of other mods for the Robby as well, like the proper robby glove and lit blaster mod. As for the 1997 B9 robot do you mean the 2 foot tall one ? If so here is a link to a you tube person who is moding there B9 so he must have the control board wiring out and maybe other videos and pictures. kzbin.info/www/bejne/aGXFg4loaKiMhLs

[@bobbova8708]

Glad to be here now. Thanks!The trend masters b9 I am tying to repair is the smaller 11 inch or so size.You're channel has some really amazing stuff.Thanks again!!!

[@ercost60]

Great video!

[@stubbs43dylan6]

Hi there...just watched your mod videos (excellent job btw..) and am looking forward to modding my own..one question..is it possible to have the gyros spin in talk only mode? Thanks again for the tutorials...👏

[@Robothut]

The gyros run off the walk walk motor. So if you wanted them to operate seperatly you would have to add a small gear motor just for the gyros.

[@stubbs43dylan6]

@@Robothut Thanks for the info...think i'll stick to the simple mods...😊 I'm waiting on a mod kit that uses fibre optics to light up the blasters.. Keep up the good work,thoroughly enjoy your vids... :D

[@PeterAgostiniJdcap26]

Nice 👍🏻 work ... glad you showed the wiring in new configuration. This would take me some time and careful handling to do. Are you going to sell the ear pullers or whole robot mods? Thanks 😊

[@Robothut]

I put the ear pullers on thing-i-verse so other can make there own for free.

[@SpaceWizardCosplay]

I did the feet mod as shown here and now Robby does the moonwalk. :P

[@Robothut]

You did something wrong. But the moon walk is cool.

[@samuelthompson3182]

Great video, thanks.

[@Robothut]

So glad you like d it.

[@Gruntess]

LOL. Blob on a board microcontroller chip.

[@Robothut]

Yep, its the way of the world these days. All mas produced products that have a custom control chip have BLOB it costs less .

[@marottamonster]

So I was taking the chest apart to look at the circuit board for the rewiring job and watching the video and wouldn’t you know it, my robots got different colored wires inside. I haven’t checked the second one yet but I’ve a feeling that it’ll be similarly wired up. Can I share you my pics? The wires are as follows: #8 - white, #7 - two wires gray and red. Nothing on 6, #5 also gray, #4 blue. The three that go “up” on mine appear to be two yellow and an orange and I think that’s the one I will need to move. Again I can share my photos if you’re up to looking at them. Thanks in advance.

[@Robothut]

Yes they seem to change wire colors from time to time. So wire placement in the pictures is about all I can share. Now many other youtubers have done video's of my mod and some of there videos might show different color wires. But in the end the wire color does not really matter what matters most is where the come from and the points that I show you to connect them. But first check out the other videos I did as well as the videos by others just in case that shows you what you need to know. I do not have a walmart robby that I can tke a part to try and compare with pictures you have taken so I do not know that new pictures would be any help.

[@marottamonster]

@@Robothut Sounds good, I figure that based on your videos [I have watched them all at least 3x each], that based on where to find wires soldered to the board and where they should be going I can figure it out. Thank you

[@InFltSvc]

That’s great that you have the skill to do this. I think I would easily pay you to do it for me but I do have a question please. Do you find that after all these modifications that it goes back together as if it was never taken apart and do you have a video demonstrating what he looks like after done ? Thanks in advance..

[@Robothut]

Yes you will find all the videos on this mod of robby in my Robothut channel. I think there are links in the description box or pined to the comment section.

[@jarmel17]

I was able to follow your video and move the wires around to make the mouth flash correctly which worked like a charm but now the LEDs on the left side of the mouth flash dim and the LEDs on the right side are bright. Do you have any thoughts on why this may have happened and how to fix it?

[@Robothut]

Its been 1.5 years since I was inside doing the mods that I do not recall much about the wiring, sorry. But if I find a reason to get inside another these Robbys again I will look for a answer for you.

[@x.y.8581]

Do what Mr, Spock says: "Cross circuit to B"

[@gensolo83]

Thanks very much for the tutorial! It's too bad the rings don't turn and there aren't any "ear" lights, but it was $20, so....

[@Robothut]

I agree, for $20 bucks or $15 bucks like they are now , it is a lot of toy.

[@geoffmower8729]

Hi still no luck with putting new battery's in now just one light is on as soon as I connect the battery's both the on off button and mode button do nothing. I will have to take Robbie apart and look for loose or dethatched wires and check the switches If I can't fix him at least I have a great shelf ornament.

[@Robothut]

That sounds like a good plan, bad wires or defective switches need to be checked. Before you make a ornament out of it you can always wire the motor to run threw the slide demo switch on the back of the body and still have a walking robot.

[@gladiatormechs5574]

i bought a few of these and converted one into a door bell.. when someone pushes my bell , my ROBBY goes off... but i noticed that the walking action switch has more features to it than just the talking switch.. but the walking switch never shuts off once it is activated.. is their a wire config that will allow the walking action to activate but on a timed manner.. i want the walking action as the door bell on a timed interval..

[@Robothut]

Great idea using it as door bell. As far as timed function that would take some doing I think.

[@OrbitalStereo]

Great video. However, now the right hand leds are dim and the left one are bright. Any ideas? 👍🏻

[@Robothut]

Sounds like a wiring problem but with out being there to look it over nothing comes to mind. Maybe another person will read your comment and has experianced the same thing can help.

[@DAS-Videos]

On mine, I have 3=Grey, 4=Grey, 5=Grey, 6=No wire, 7=Red, 8=White. The mouth circuit board has a Grey, Yellow and Red wires.

[@Robothut]

Yes kind of crazy how the control board LED wiring has changed so much. Kind of like different assembly houses are building the toy.

[@DAS-Videos]

@@Robothut Looking again, 7 has a red and a grey wire, and what I called 3 is marked with a code. I am thinking that the circuit board is the same and they used different color wires.

[@DAS-Videos]

@@Robothut I put pictures of my circuit board here kzbin.info/www/bejne/r4SqoGqsq86lZpo

@@Robothut Welp it works. The wires were just different colors. Thanks for this great tip. Now to find something to make the mouth blue.

[@frightrisk7407]

How do you take it apart to fix the mouth wiring? Do you have to remove the head or take the torso apart?

[@Robothut]

Yes it is fully covered in my many videos on this Robby toy. Check out my Robothut youtube channel. The ear blasters have to be pulled off the dome lifted off a few screws removed then the mouth parts will pull out.

[@galacticmodeler3173]

THANKS...

[@stevenanderson8986]

My Robby is a little different. Got red, yellow and grey from the mouth LED’s. Red is on 7, yellow is on V with the other two yellows and grey is on 6. Do I still make the changes like you did?

[@michaelmcdonnell6523]

I wish you would make a video showing how to take the rest of the robot apart, not just the head. Thank you

[@Robothut]

I did 3 videos on the robby, I think that shows most of it. But I think I saw a video on you tube by anouther collector that does show the robot stripped for painting.

[@drakozero8]

I'm having issues with the Walking. Nothing seems to be broken I've opened it up and everything, but for some reason when I switch for the walking feature the mouth area flashes but nothing else happens.... any assistance would be highly appreciated thanks.

[@Robothut]

Try brand new batteries, even one low or defective battery will make this happen.

[@dennisstahl1183]

My Robbie came with a black wire soldered to #6 (goes to head), in addition to the individual black wires on #7 & #8. What happened? I don't want to take the head off & I can't see a way to pick out the yellow wire to solder to #6, from the 3 yellow head wires without removing head. Any suggestions other than removing all 3 wires from V and resoldering one at a time?

[@Robothut]

I do not see an easy way around it. They do like to change the wire colors it seems from other guys posts. But for the most part the wire color does not matter as long as the wires are moved from the positions I show to the new positions things should work.

[@dennisstahl1183]

@@Robothut Thanks, but I still don't know what gives with that black wire (black wires are on 6, 7 &8 from factory) that is soldered to #6 Where you would put the yellow wire in question? Leave it be on the #6 position?

[@Robothut]

@@dennisstahl1183 What I would do in your case is first you have to find out what wire that is soldered to V+ is the mouth wire, so remove one of the wires from the V+ pad and see if the mouth stops working or the dome light stops working. Once you have the mouth wire located you can then move the wires what ever colors they are from 6 & 7 pads to the #5 pad and the mouth wire you just found to pad 6 or 7. Since 6 and 7 are the same thing either pad will do.

[@dennisstahl1183]

@@Robothut Thank you very much! I'm 71, and I think I went into an anxiety driven senior moment. LOL. I got the correct yellow wire to the mouth first choice. One of the 3 wires appeared to be longer than the other 2, making me believe that one likely went to the mouth, as the other 2 wires had further to go into the head, and had less slack left, if you know what I mean. It works fine, anyway. I had already sprayed the exterior of the mouth Tamaya transparent blue, and I can live without the black separators of the mouth. And now, having the mouth working right, is enough to make me happy! "The Day the Earth Stood Still" and "Forbidden Planet" are my all time SCI Fi favorites..

[@afoxyjim6625]

Thank you for your quick reply, I've come acrose a few small receivers that looks like they might be small enough to fit inside, worse is I may end up with a Robby with a back pack.

@@afoxyjim6625 The little table top RC cars that they call Coke can cars now days, have digital RC design, the control board is the size of your thumb nail. They can drive 2 motors OFF and forward and reverse. So you can use them to control 4 motors if you do not need the forward and reverse function. Also you can trigger sound effects with them.

[@darthgoggins1747]

What would you charge to mod one ?

[@Robothut]

The problem is the cost of shipping the large robot and box and then paying me for the work and add in the cost of the robot. It adds up and that's why I did all these videos so people could DIY it on the cheep. If money is not a problem for you then yes I can mod one for you.

[@darthgoggins1747]

@@Robothut I'm still curious. I haven't even seen the robot up close yet. I didn't know they existed till your video and after seeing it I ordered one from ebay new. So I'm open to anything. I could do the work but I'm a disabled vet and sometimes doing fine work like this my hands shake. And if not would you make those clips to take off the ears for sale ?

[@Robothut]

Hope you did not pay a lot for the ebay version as they are only $20 bucks at Walmart. And now that they have been out a few weeks more and more walmarts are getting them in stock every day. Now as for the 3d printed clips, I could make them and ship them but first you might check any schools in your area or even libraries , maker spaces or even friends and kids that might have a 3d printer. 3d printers are every where these days. There are also online 3d printers that you just give the link I provided too and they will print the part and give the cost up front.

[@darthgoggins1747]

@@Robothut good to know. I know nothing about 3d printers and I'm not ashamed to say i paid 50 for my robot. I checked walmart online and they showed nothing available. As for my local stores employees hoard items like this hiding them behind things on top shelves so they can buy them all sell on Ebay. Not fair i know but it happens. I've missed out to many times because of this. My trendmasters Robby came from Monsters in Motion because of local retailers. I wouldn't have gone beyond 50 for Robby the Lost in Space B9 is another story as he's my all time favorite.
