This video demonstrates the iterative design process for building a LEGO Great Ball Contraption (GBC) intake module, showing how to systematically test, identify issues, and refine mechanical designs through trial and error. The builder tests the intake module independently, creates a feedback loop for continuous operation, and addresses common problems such as ball blockages, improper ramp angles, and reservoir height issues. Key principles include: testing components independently before full integration, using feedback loops for continuous operation, adjusting geometric parameters like ramp steepness and gap widths to improve ball flow, and recognizing that temporary blockages often self-resolve while persistent issues require design modifications. The video emphasizes that GBC design requires patience and systematic problem-solving, with the builder planning to test the final module at a robotics competition to validate its performance under real-world conditions.

LIVE • Rebuilding Robot Dreams - Part 2Added:
Hey, what is up everybody? Hopefully this all works. Today we're going to continue working on my rebuild of the Robot Dreams GBC module. And today specifically, we're going to be looking at the intake module. Uh I got most of the actual robots working last week, although I did tweak some things which we'll go over a bit later. Um, but for now I just basically got to finish off the intake module, which was kind of working last week. And obviously I've had this working before, but there was some like minor issues with it. So I did a little bit of reconfiguration, but right now we're going to test this fully, make sure it's actually working, uh, put it through its paces and try and, uh, deal with any issues that may pop up. Uh hopefully there's some people that might show up in the chat.
We'll see.
Perhaps not. Is this thing actually working? Oh yeah, we're live a minute.
Is this even public?
Make sure. Oh yeah. Oh yeah. Oh yeah. Oh yeah. We're good. We're good. Okay. Uh yeah. So, I guess first thing we're going to do is actually have to stick a motor onto this. Uh, I've found testing intake modules is definitely done best done independently instead of like hooking it up to the entire module. Basically, this accepts balls at the beginning and then routes them to basically just feeds.
We'll feed the GBC module.
Uh yeah. So that is I wonder why is there a reason there's no I see we do have some viewers. Nobody's Give me a chat message. Somebody just somebody give me a chat message or send me an Instagram message or something if the chat's not Oh, we do have some chat. Excellent. Oh, Deborah is in the chat. Good to see you. Perhaps the chat is just very delayed.
Who knows about that? Hopefully my settings didn't get wonked out.
Mel's in the chat. Excellent. Eli Dragon Shadow. Hello. Hello. Wii U XG. Yeah.
Okay. Excellent.
We got a little bit of chat. Okay. So, yeah. Step one, we need a motor.
I do have a lot of motors kicking around. Uh would like an M motor actually, but I don't seem to have one.
That's fine.
So, in order to test this, I'm going to stick a motor on it. I'm also going to we're going to build a little feedback loop so that the balls when they come out the top, they just feed right back in. So, we can just run it continuously and uh yeah, it'll be good to go. Uh I do have this gear on the end here, but that's just for uh that's just for interfacing with the actual drive module of the robot uh of the GBC module.
which we will probably hook it up at some point in the stream.
Dragon shadow attempting to work while watching. So limited chatting. Oh, that's fine. Uh, no worries, my friend.
Just uh just wanted to make sure the stream was all in good operational shape.
Happy Friday, Morsalo. Excellent.
Yes, it is Friday.
Looking forward to the weekend.
Actually, tomorrow is supposed to be decent weather here. It's supposed to rain on Sunday, though. Um, so Crystal and I will be doing something outside, I'm sure, tomorrow.
Although, I guess it's been a couple weeks. What's happened? Oh, man. It's been a crazy couple weeks, actually. Our car has developed some issues. So, it ended up pretty much well, not dying, but it needs some work. Okay, here we go.
Okay, let's just uh throw some balls in. Make sure they're all working. Yeah, our van developed some issues. So, we're actually driving a rental right now.
And uh hopefully that gets fixed today.
Excellent.
Oh, it looks so good. I think I nailed I think I ironed out. There was there were a few minor issues with the the tray feed last week, but uh but it all seem to uh it all seem to work. So far so good. Of course, you don't know until you really you really run it through its paces. So, uh yeah.
And yeah, what else is new in the last couple weeks? Yeah, we had some card trouble.
But whatever, that is what it is. Uh, what Lego sets were announced? Oh, the pinball. Classic space pinball machine, which should be pretty exciting. New space baby coming out.
I guess that's like a July 1 release, which is bad timing for me because we'll be traveling for the summer. But hopefully in the fall I'll build that and get another space baby.
Okay. Uh so yeah, we want to create a little feedback uh feedback thing. So actually I busted out my old marble run pieces so we can build some uh just build some channels.
So in theory theory, actually we're just going to mount some uh mount some ball run channels into this to route the balls back into the intake.
Uh, what about Darth Vader? Oh, yeah. kind of the mini fig Darth Vader or I guess big fig scale Darth Vader was released or announced.
It is pretty cool. Actually, I don't know if I'll pick that up.
I feel like I built one big fig.
Maybe that's enough for me.
Will this ball get routed?
Excellent.
And then we'll stick another one. It's a bit long.
We'll stick another one on here.
It's actually not long enough. Actually, we'll just get the long one.
It's okay if it sticks out a little much.
G. Jacobson, good morning. Excellent.
Any new modules in the making? Andy James. Uh, no, I haven't. Uh, I mean, kind of.
I've been tinkering.
I do have a prototype somewhere. Oh, I I'll get it out later to show you guys.
I think I may have shown it on stream before actually.
Actually started working on it like years ago. Well, years like actually probably literally years ago.
Okay. Uh, will this route balls?
Oh, excellent. Easy peasy lemon and squeezy. So, in theory, we have some very rudimentary ball return.
Clearly, this is going to require bigger sides at some point.
Whoa, one fell out.
Let's see. Definitely an issue here.
Oh, yeah. Okay. So, there's a minor issue there.
This is why we test eventually sorts itself out. But uh Oh, and we do have an issue with balls coming out here.
Okay, so clearly we have some issues.
Uh G Jacobson late to the build party. No, you are in time. Uh Creeper Man, hey yo, what's up? You're making those GBC. I am indeed.
Remember when Speedraer got the Lego treatment, KJ? Uh yeah. Was that a thing ages ago?
Okay. So, there's a couple things actually. It's because this uh this doesn't quite go down low enough for the ball to consistently.
So, I might actually raise this plate.
We'll see how that works. Uh, first I have to actually want to just dump those for now.
We'll clear clear the intake.
And actually, I'm just going to raise Well, there's a couple things we're going to do.
or at least we're going to try. Uh I'm actually going to raise this up a plate which might introduce some other problems but uh Heaven Moon Time to party. Oh, I have missed the last two weeks because I thought it was on Friday. Yeah, I know. My schedule's been a little bit all over the place.
Do you know a good sites where I can buy GBC's from?
Uh, they're so cool. Wish you could buy a GBC somewhere. Yeah, cool. Thanks.
Cheers. Uh, actually, Build-a-Temach sells some very small uh GBC modules.
Uh, they're pretty cool, actually, cuz they're like a decent size, but they're Yeah, buildock.com.
They don't sell any of my GBC modules because I don't really have that many, but uh they do sell some.
Why does everybody ignore me, Julia?
Ulu. Well, because that's the first time you posted a message. Are GBC balls Lego by the way? Misla. Yes, these are these are official Lego. They're like uh soccer balls, actually.
Official Lego soccer balls. Okay, we have that done. And actually in my previous prototype, I did have another layer of stuff here which I might bring back to try and mitigate the I had this tiny little wall in front of the ramp.
which we'll see if that actually potentially mitigates.
No, actually it shouldn't really do anything to be honest.
No, cuz it's not high enough. Uh interesting.
So, that won't do anything. Uh, oh yeah, I want to raise these sidewalls up a little bit just to constrain the balls a little bit.
Oh, Terra's in the chat. Excellent. Good morning. Hey everyone. Let's have a great stream today. Yep. Let's do that.
Creeper man. Watching GBC's C's are so satisfying.
Yeah, some of them are very mesmerizing.
I can see someone started earlier than to post the time. Did I? Why didn't I post this time?
Sorry about that. I have no idea. Oh, I said it scheduled it for 10:30. I'm sorry.
All right. Well, I guess uh I meant to schedule for 10, but uh clearly I done messed up. Uh yeah, no worries.
It's my bad. My bad.
It's 10:30 somewhere. Yeah, probably.
Erica took his time and got some snacks.
Deborah was here on the on the ball.
Clearly, they were paying attention uh to the stream, not the time.
Uh, interesting. It's clearly now it's not a deep enough angle.
Yeah, it actually goes best with a bit steeper angle. So, uh, interesting.
So that was a terrible idea.
This is the joy of GBC is that uh it's a lot of trial and error.
It's a lot of trial and error. Things often don't work out the way you want them to.
So, this ramp right now is not quite steep enough to to push the balls with enough force into the into the stepper mechanism.
Actually, I think I have enough play here to remove. I'm going to lower this first step by one plate, which should actually still work, I think.
I'm just going to get a It's not going to work.
I just want to Oh my gosh.
I want to minimize how much finickying around I get to do with this, but uh obviously it's a bit ghetto, so you know, but that'll support that.
Eli, turn your notifications on to not miss. Yeah.
Uh, should put a 1x3 wedge where the gray 1 by two pieces now.
1x3 wedge with a gray one by three wedge.
Oh man, I just cut myself with Lego.
It's crazy. Um, I'm not quite sure what you mean, but uh, what is GBC? Great ball contraption.
Yeah, it's a great question.
Uh, it's just a mechanism for routing balls.
Okay. Anyway, uh Oh, spilled tea everywhere.
Okay, I may tweak that a little bit still, but it's probably working well enough for now. Uh I'm actually not too concerned about I'm not too concerned about this transition long term cuz there's uh a lot of flexibility in adjusting heights and stuff here. So, at some point, I'll just uh nail that with some tweaking. But the the little potential blockage here that happens every once in a while is a little more concerning.
H. Oh, yeah. There we go.
Interesting.
It does pretty much sort itself out. But actually, I think I think all it might need is for this gap to be a little narrower.
But clearly it happens often enough right now that it's very reproducible, which is actually good cuz All right. Not even half an hour to cut yourself and spilled tea. Yeah. Yeah. I cut myself with the freaking Lego piece.
Ridiculous.
The background looks similar to another YouTuber's background.
Who knows? Uh oh, Bill is here. He made it. Yeah.
Sorry, the scheduling was off. I don't know why I I scheduled it pretty late last night, I guess, and I was half asleep.
Should that gray corner be rounded?
Yeah, we definitely need to do something with this gray corner. Um, thankfully it's easy to remove, so it's easy to uh to adjust. Actually, I just want to make it a little bit Just want to make it a little bit thicker.
Actually, first thing we're going to try.
I'm going to make it one plate thicker.
So instead of just having a 2 by 2, I'm actually just make it thicker by a tile.
I'm going to stick a tile on the side of it like so. That way, so just it takes up more space.
And I think there'll still be space for Yeah. three balls to to go through that gap, but But it might just push this ball further enough back that it doesn't ever catch on the ball that's already in the channel.
Oh, interesting. Did you see that?
There's definitely some potential now.
It's just a little bit too I think what I'll do. Oh, no. Clearly, we still have this issue.
Oh, it's even worse now.
Oh, interesting. There's something else we can try, too. And that is I'm going to push the uh the reservoir up another a whole other plate.
So, the mechanism that pushes the reservoir up, I'm actually going to increase its range of motion so it comes up higher. I just add another plate.
Basically, there's a cam here that basically pushes this up and down. And if I increase the thickness of this uh plate here by one plate, it'll actually push this reservoir up higher, which might do something.
I got a ball stuck in here.
Ah, the joys of trial and error.
Bill says that orange ball is causing problems.
Time to remove it.
Yeah. So now when it pushes the balls up. Oh no, I got some Oh yeah, but now we got some interesting because I added this. Oh, we got some potential blockage here, which is always an issue when you constrain the space the balls are allowed to run through.
Basically, whenever you constrain any kind of channel with the balls running through, you risk them uh creating a blockage.
Uh but so far, the actual depositing of the depositing of the balls. Oh, no.
Here we go.
Fix this out.
Yeah, we like the blockage. Interesting.
As long as it fixes itself, it's actually not that big of an issue.
For the blockage issue, I'm actually going to replace I'm going to try replacing this tile with a curved slope.
We'll just let that run for a bit.
As with any GBC, you really just need to run it for like hours on end.
As long as there are plenty of balls to go around, a little temporary blockage is hardly noticeable in the long run.
Right.
That is true.
So, I'm actually going to try and replace that 2 by two.
So, I'm going to try this profile on the side.
First, we'll clear out the mechanism.
Oh, yeah. See, we got uh some blockage at the constriction, but we're going to try and remove that constriction.
So, yeah, I'm going to replace.
So, instead of having flat profile here, we're going to have a curved profile, which will hopefully lessen that issue.
But again, we won't know till we try it.
It's actually not too bad. Uh, I can still see potentially it might jam up, but it doesn't seem to actually be that bad.
A little temporary blockage. Oh, yeah.
out. Well, actually that's because I need another to build that wall up a bit better.
And at the front, it's funny. It's definitely like you can see it trying to create some kind of blockage, but uh it definitely sorts itself out for the most part.
Now, it's actually not doesn't look too bad. I should really be timing it to see how long it's going to fake. But, uh, Bill, that's what the doctor said, too.
Yeah, temporary blockage.
As long as it fixes itself. Uh, when I was a kid, there was a ball clock with an alarm that would pick up metal BBs and drop them off levels for seconds, minutes, hours.
You'd be the one to make the Lego version. Well, I have news for you. I actually did probably like 15 years ago.
It's actually I think one of the first videos I ever posted on this channel.
Really hitting the archives there.
I think you need to turn the slope the other way.
Robot robot race. Nice. You need a partner.
Do you ship?
Yeah, I mean I will make instructions for this hopefully soon once I get it all working. Um, so far this has been working quite well actually. Excellent.
Oh yeah, let me uh Oh no, we got blockage. Oh, interesting.
Well, that was the fourth Lego video I posted on my channel.
13 years ago was the ball the ball clock.
Didn't you put the ball clock in the Lego world con thingy?
Probably not me. No, I think some other people have checked it out.
But if anybody wants a blast from the past.
There's my original ball clock.
Something to prevent the rightmost ball from climbing on top. Oh, interesting.
Yeah. Yeah. Okay.
Yeah, there's always a risk uh at some point we just move the potential blockage back further, but obviously this is clearly a catastrophic blockage scenario here. Uh yeah, like in theory you could just like cover this in part, but then We just uh it potentially gets hung up further back.
Although I guess I could cover this whole thing.
Yeah, this this prevents the balls from Oh, yeah. But then you risk risk that happening.
So, it's not too bad, but I have a feeling that longterm this could also introduce a few issues.
Oh, yeah. See, we still get we still get some potential issues.
Actually, I could see since we have Interesting. I'm going to try just covering off.
Oh, no. I don't think that'll work.
Interesting.
Interesting.
Clearly, there's still some issues to iron out.
Uh, add another layer to the curved edge block that guides the balls.
Yeah, maybe we'll make that a bit higher. Uh, why don't I discard discord room for your followers?
Great question. Um, because I just don't need one more thing to look at is the short answer to that. Real creativity. I wish I could make that, but my batteries died.
But year ago, I made a two three foot mech suit. Wow. Iron Man set. That's pretty cool. JB Lewis, if you put a 1x3 plate in the gap left by that curve tile, I think that would keep the balls from climbing on top of it. That's what seemed to cause the last jam one by two.
We have a problem. Yeah. So clearly, yeah, I mean, we can try and make this a bit taller. That's great suggestion.
Clearly. Oh, I'm just going to empty that out.
Just take a while.
Got a few pieces.
Round off the left corner could help maybe.
Okay, I'm going to make this a little bit taller.
And then we'll actually I'm actually just going to add just going to add some height to it.
Oh no, the balls everywhere. Interesting.
We do still have this uh I mean I guess this problem is mitigated. I can just remove this.
Like if we just remove that then we never have a thing for it to block. And theoretically, yeah, they should sort themselves out.
Yeah, if you ever get a ball that like rides on top of the stack, it should eventually just flatten out.
Yeah, like there there was a ball sitting on top that eventually just and then yeah, there was a small blockage here, but that kind of sorts itself out.
put a cover over it if anyone agrees.
Yeah. The problem with putting a cover over it is that eventually Yeah. I mean, it's not a bad idea, but I have a feeling it's just going to create blockage potential elsewhere.
Vertical 1x3. Oh, to make it a bit of a horn on that funneling piece.
Oh, our hamburgers's in the house.
Excellent.
Yeah, I think we can still make this uh bigger. And yeah, you're right. I think we should just uh Can I do this without completely draining?
I'm actually going to We're just going to raise this up a little bit.
I'm not sure it's exactly what you mention meant me meant, but we're I'm actually just going to raise this up like quite make it really tall just to mitigate the ability of the balls to kind of scooch around the top of it.
I think most of the bigger issues happen when the reservoir is really full.
So, I'm just going to ram it full of balls.
JB Lewis, it's even better than I was what I was thinking. Wow.
It's a team effort.
Real creativity. What's a project that you made that you're most proud of?
proud of.
Oh, Mac build bricks. I missed you. Good morning.
Actually raising that up seems to actually have a pretty good impact on uh consistency.
So yeah, it's a great idea.
I mean, I'm okay with it. Oh, yeah. Here we go.
Oh s it fix itself minor issue.
I'm okay if it fixes itself eventually and even if it does bottleneck very rarely then I'm happy with that as well.
Oh yeah. Project you're most proud of.
Yeah. I don't know. Most proud of versus like favorite.
I mean, if I actually get this whole thing working, I would definitely be proud of that cuz it's been it's been a long time coming to iron out all the kinks in this.
Have you ever made a vacuum? No, I have not.
Uh, dragon shadow. Now I just need to rig the holding bucket to regulate the speed. As the bucket fills up, it speeds up. As the bucket gets emptier, it slows down. Oh man, that's like next level.
But actually GBC has a very strict uh specs that the mod modules have to adhere to. Basically it has to push ideally nominally one bottle per second is the is the rate that your module has to handle.
So actually I don't know what the rate is of this. Let's time it. Uh, one, two, three.
Wow, it's actually going way too fast.
One, two, three, four, five.
Oh, it's actually still going a bit too fast.
Three, four, five.
This is about how fast it should go.
Try it again.
One, two, three, four, five, six, seven, eight.
Well, it's still a bit fast actually.
Eric, perfect timing to get that new speed controller. Yeah, it's new. This is pretty sweet, actually.
You can really fine-tune the speed.
One, two, three, four, five, six, seven, eight, nine.
Yeah, I think this is probably bang on for for production speed.
Dragon shadow one only get to one Mississippi.
I'm actually looking at the clock. have a have a clock in the background while I'm counting there, but I have it timed. The actual drive motor for the actual full module uh is an XL motor running at max speed and I have it geared down so that the timing is is right. So in theory when I connect this to the actual module it should operate at the right speed.
I mean this is seems to be working pretty well so far.
I might be happy enough with that. Even if it does have a few minor issues, I'll do a full test on Sunday. Sunday, I mentioned a couple weeks ago, Sunday is there's a local robotics competition for the kids this weekend in Ottawa. So, I'll bring it there and I'll run it all day and then I'll really be able to see what uh what issues may develop.
Yeah, so far seems to be pretty decent.
H do you mind if I give you an idea for a next project later on? I mean, feel free to give me ideas, but uh don't be disappointed if they never come to fruition.
I have a lot of I have a lot of things to work on, sadly.
Most of them take a lot of time. At this speed, it's ample time to fix any blockages. Yeah, as long as they sort themselves out in a reasonable amount of time, then it's not really that big an issue.
Craig Chabala, what speed controller is that? This is a FX bricks.
I don't know if they're actually selling them yet.
I think they're on the website, but they might not be shippable yet.
If you go to FX Bricks, there's a blog post where Mike talks about new products.
This is one of them here. I'll add a link in the description.
Yeah, I think they say sold out, but it's because they haven't they're not avail they're not they're not available yet. He's never sold them yet. I just have a pre-release version of it. Uh I don't know when. Obviously, he wrote this blog post in February. So, as you may or may not know, getting things manufactured is uh there's there's a lot of things that have to be done.
So, uh everything usually takes longer than you think.
Still in beta basically. Yeah, pretty much. Yeah. Although this is I think this is I think these pretty much nailed the design.
I think it's just a matter of uh putting into production right now. Need a Kickstarter. Yeah, I mean the Kickstarter doesn't help you manufacture things. Uh that just raises money.
So making a tiny crane carrier that will kind of work like the robots. Oh yeah, maybe interesting idea.
Okay, this has been working for like at least five minutes. So, I think we're ready to hook it up to the main module and see if it actually works in production.
So, I'm going to just cycle it through Oh, and just as I say that got some minor blockage here.
Be interesting.
Yeah, I can still see potentially maybe I'll tweak this a little bit.
But I feel like we're definitely really close. Definitely really close. There might be some minor tweaking still to do, but um but I'm pretty happy with that, at least for Sunday's uh show.
Okay. So, I'll make some uh I'll make some room.
Actually, I'll take So, I'll take this motor off.
The other thing that I've been toying with is these buckets. Uh, basically all this week I was playing with them cuz right now I've been using these, but these are really old. These have been out of production for I don't know 20 years or something maybe. Actually, I should really look that up. I don't because uh it's all great and for me to use them because I have some, but uh if anybody else wants to build this and there's none available, then they're not going to have a good time trying to find them.
What the heck these are called? Must be some kind of wheels.
Oh yeah, it's a tread.
Oh yeah, here they are. Technic Tread Hub.
Oh yeah, they stopped being produced in 2007.
So yeah, almost 20 years ago. Uh, so yeah, even though there are quite a few available on BrickLink, they definitely don't make them anymore.
Oh yeah, and they're not that not that actually that expensive, but still. And I don't foresee this model being all that super popular.
So, you know, it's a good option, I guess, to have. But I was experimenting with other ways to do it. Actually, LEGO just released this new bucket, which I think is going to be great for It's like a widemouth bucket that the balls like sit in really nicely.
And I only bought two of them cuz I at the time I was like, "Oh, that's a new part. I should get a couple. See if I can do anything with them." And now that I've decided I want to do something with them, I need like a like well at least five of them.
So I'll probably order more at some point. Uh okay. So, uh, step one is we're going to just mount this onto the front here and we'll interface that gear. So, now in theory, Hold on. I gotta make some room.
Yeah. So now in theory we have feed. I'll actually zoom out a little bit just so that and then put my motor back on.
Then I'm going to need some more balls.
Uh, okay.
I lost the chat.
What piece do you have for the rack?
I don't know what you're referring to.
Sorry. You almost need something to jostle the storage box to keep them moving. Yeah. Yeah. Yeah. Some kind of agitator. That's definitely a valid uh or a common strategy for a lot of reservoirs is just to have some kind of extra agitation.
Uh yeah, it's like a super common strategy.
So yeah, maybe I can introduce that. I would I'd rather if I don't need to I'd rather not do it just because it adds more mechanical complexity. I like to keep things as simple as possible if they work. But you know yeah if I have to then that's something I can do as well. Uh yeah I agree mostly but it might be jammed and stop the process.
Uh JB Lewis, I was thinking the same thing. Something to poke the balls in the hopper on each cycle. Yeah, push mechanism instead of the tray lowering and gravity, but pushing could become stuck the same way perhaps. Yeah, I think uh obviously people have been making hundreds of GBC modules over the years, probably thousands. This is definitely not a new problem that we're trying to solve. Uh, and it almost seems like most most uh strategies always develop some kind of issue. Uh, oh, Jay Tuker is in the house. Good morning.
But that would need more timing to get time to get timing. Yeah. Yeah, I can show you the previous one I had.
In the first version of this model, I actually had this uh feed mechanism which actually works pretty decently.
And it basically it's got this uh this rotates which jostles the balls to try and unblock them. And this actually works pretty reasonably, but there's still occasionally sometimes when the balls get jammed a little bit.
Um, but it probably works like 99%.
Uh, and the one of the reasons I didn't reuse this one is actually it's a it's very complicated in here. Uh, well, not that it's all that complicated, but there's a lot of moving parts and I actually needed five steppers for this module module uh, instead of four. So, I didn't just want to make this longer. And also I just wanted to challenge myself to do something a bit different. Uh so I decided to go with this which actually the stepping mechanism is much simpler than on this model. Um but in theory the reservoir like I could have just used the same reservoir.
But I thought I would try this instead just to give myself something more interesting to work on.
Uh, Crystal's in the chat. Have I heard about the car? No, I have not heard about the car. Although, if Crystal's still around, we just before I went live, this is the book Crystal and I are work working on.
Calabogi Bowlering. We made this. We made this guide book and uh this is like the the proof that the printer sent us.
This is what we spent all winter working on. It's like climbing guide book for our local area. So, we made this entire thing which is pretty sweet. It looks really good.
This is like the pre pre-printing proof.
Uh so hopefully in like a month we'll get it printed or the printers will we're still waiting for like proofs of the cover and everything. But uh but yeah, it's like a little guide book for the local climbing in our area.
It's got all kinds of fun things in it.
Yeah, we have some local art from local artists in here as well, which is pretty awesome.
There's a few at the back.
There's another one, table of contents, some pretty pictures of some cool full page photo spreads.
Yeah. Anyway, that's pretty exciting.
It looks really good.
But okay, on to more Lego things. Uh, but yeah, our car, as I mentioned at the very top, has some issues. It's in the shop right now, but I haven't heard from them. Theoretically, it could be fixed today, but I haven't heard anything yet.
Uh JB Lewis, very cool book. Oh, thanks.
Yeah, Deborah. Oh, wow. Yeah. Uh are you thinking of putting detail uh for what? I don't know. Uh Eric looks great. Ephrendo looks incredible. Putting detailing the build.
I mean, uh not too much. I mean, I think the I I don't want to distract from the robots themselves. So, I tried to put as much detail in the robots, and I want the whole frame and everything just to be kind of like in the background. So, I probably won't put too much detail.
Well, we got one.
Oh, yeah. Clearly the green guy is dropping some right now.
But I find this new little reservoir I built, it actually works really well.
And it's using parts that are currently in production, which is great.
I thought the green guy's paycheck.
Yeah. Oh no, I missed that one. What happened there? Was it green again?
I found when I was testing all week, green definitely had a lot of issues out of all the robots, the green one seems to be the most unreliable.
And I have no idea. I I even rebuilt them uh once.
It's so interesting that he's in theory built the Oh, the blue one was trying to pick it up. Okay, good to know.
Uh, sounds great. It's a blue one when trying to pick it up. Okay. Agree with Eric.
Blue guys acting up. I see. Okay. Uh, okay. Okay, that seems to work reasonably well.
Clearly, I need to build a loop for this as well. Uh but we'll uh maybe we'll do another run through just to look at them all. Maybe I have the full thing. Obviously, we can't see the last two were the blue guy. Okay, excellent. Uh, Hugo Cardoso, hello, Lego builder.
Upsar, what version of Hungry Hungry Hippos is this?
Yeah, great question.
Brand new, never before seen. Hungry Hungry Hippo is 2026.
Uh the M the Red is missing rounded bricks on his base. Wasn't it done last week? Oh, no. I never rebuilt red. I only rebuilt the other ones. Uh the red one I I didn't got to because it was connected to the to the intake and everything. I didn't rebuild it last week. Uh so he still needs to be rebuilt.
And actually, I did tweak I did tweak a little bit of the design of the there's like a stopping mechanism to basically like make sure the robots don't overshoot the targets. I kind of rejig that a little bit last week. Uh so I think only I think only two of them have the new stopping mechanism.
Uh yeah, it's a very minor thing that most of the time isn't noticeable, but uh but anyway, so yeah, a few of them still need a little bit of work.
And also, yeah, I still need to decorate the very bottom of these pedestals just to cover up the studs mostly. Um, and then uh obviously I still need to rebuild the intake just to cuz right now it's still kind of like prototypy. It doesn't actually look that great. Same with the drive module.
I kind of I think this is like the third version I built and I think I'm finally happy with all the mechanics of it. But I still need to do the final design just to make sure it all can be built uh well like in a logical order and make sure it looks actually good. Also, it needs a little bit more reinforcement. I think if you're running it for hours on end, it just needs to be like rock solid.
Okay, we'll do another pass and see what happens.
Oh no, right off the get- go.
Clearly take a while to warm up.
Oh yeah, red appears to Oh, all kinds of problems this run.
Oh, we actually have it there was a massive blockage on the intake, but it sorted itself out.
Oh, red.
Problem is there's too many things to look at at the same time.
Wow, that wasn't very great. Actually dropped a lot. Uh, when red lets go, the ball seems to need to settle down. Yeah, the red isn't releasing very well. Seems to jostle quite a bit. seems the viations from the robot's movements caused the ball cups to shake a bit, so they're a bit off sometimes.
Robots grippers can't get the proper hold.
Green's ball doesn't jiggle that way.
Yeah. Um, yeah, absolutely.
There's clearly perhaps some minor adjustment on the shovels for some of them.
Oh yeah, that's even worse.
Oh yeah.
I'm going to turn them in a little bit.
Well, that seems to be a little bit better.
Okay, red looks like it's uh I just turned the shovels like in a little bit so that I think uh depending on their orientation, the edges of the shovels can kind of catch the balls on the way out which jostles the balls quite a bit.
Oh yeah, I think brown is already kind of like that. Oh, so is green.
Yeah, but I think you definitely need to do a little bit of, you know, tweaking.
Oh, Brian the Brick made it. Long time no see. It's been two weeks. Yeah, it's been two weeks. I didn't miss much, did I?
Yeah, I mean, actually, you missed uh Yeah, probably not much, actually. Not much has changed since last week, actually.
Could the rubber band be losing the elasticity if it runs for two weeks?
Yeah, that's definitely another variable that and actually the rubber bands that are on here, I haven't replaced any of them in at least a year. So, some of them are probably getting a bit old.
But yeah, we'll see. In theory, they should be able to last a day.
But yeah, it is another variable in the system that probably has some variation between them.
But red appears to be working a little bit better now.
Oh no, my intake actually the uh interesting the gear slid off the axle the Drive gear.
Heat. Heat.
Yeah, that was a whole container. And I don't think any robots actually dropped any balls.
So, that's promising. Uh, red definitely had some issues, but I think rotating the shovels helped a lot.
The other ones appear to have just sorted themselves out. I mean, I guess they're kind of like humans. Take a little while to get going in the morning.
Yeah, I think they're uh so that is the speed they should be at. Yeah, I'm pretty sure I'm pretty sure this should be about one ball per second.
Um, so this is the speed they should be operating at.
Yeah, the intake seemed to work pretty good. Um, yeah, it still might need a few little minor tweaks, but uh, for the most part, uh, yeah, it seems fine in terms of the mechanics. So, I think I'll probably stick with that.
Obviously, like I said, I'll rebuild it just so that it's nice and solid and has like a cohesive style.
I think the stepper mechanism is like I've never really had any problems with it for a while. So, I think that's good. And then the drive system seems pretty nice, too. So, yeah, they just need to be all rebuilt. Same with the red guy. Needs to be rebuilt.
And I might tweak the the look of some of the robots, obviously. Well, you can't see actually, but uh the orange one the orange one is missing a head. Uh so it needs a head. Last time we put some space babies on it. Oh, and actually I did order uh Yeah, actually I think uh we're probably pretty good with with this for today. And I think I probably will order more of these cups.
I think I will go with this style.
At least I'll try it on Sunday. Well, actually, I won't get them Sunday. I have one other cup design, which is using these uh cylinders.
It's not quite as good, though. I think the ball the balls take a long time to settle down inside them. They jostle a lot. So, it causes some problems if they don't settle before the next uh robot comes to pick them up. So, I'm not actually too happy with that one. It It mostly works, but it just seems to result in a little bit more uh a little bit more drops.
But yeah, it's pretty cool. Uh I did actually get a couple sets in the mail.
I got the rocking plants, which we'll build on stream at some point. Maybe we'll do something with them. Uh, but I also got my little Mandalorian speeder with Grou. I think we'll just pop this open now and see what baby Grou looks like compared to the space babies.
Actually, I probably won't build the speeder.
Mostly I want to see what Grou looks like.
Oh, yeah. Nice.
He's so cute.
The space babies will have a little alien friend.
to hang out with.
That's cool.
Actually, I'll just put the rest of this. Maybe we'll build the speeder at some point as well and motoriize it or something. But uh for now they've got a new friend. Yes, they do have a new friend. And I guess we'll get a I think the pinball machine has a light blue space baby I think coming.
Oh, I need to get the updated version of Grou. Yeah, I don't know. Yeah. Does he have hair or something? I can't remember.
Well, Bill Grug has the same body mold.
Yeah, it's the same body mold. Looks identical from what I can tell.
So, if we want uh Grou in a space suit.
Oh, it actually looks pretty good in a classic space suit.
Somebody else was asking about other GBC modules. Uh, and this is like a I think I did I don't know if I showed this ever on stream before. I actually built it a while ago, but uh and actually don't even know if it works at the moment, but we'll try it out.
Uh, it's just another This is just like a standalone self feeding robot. That's a bit bit fast.
Oh, the new Rogo has a different body. Oh, same head. I see like just different printing on the body or I assume.
Oh, a new mold. Interesting.
Let me check that out.
Oh, I see.
Oh yeah, look at him being all fancy.
Well, that's less exciting. Oh, and there's a Christmas one, too.
It's not as uh I mean it's more I guess accurate, but uh it's not as cool as the classic space as the the baby baby mold.
GBC module gives me forever alone vibes.
Yeah.
Uh yeah, right now this is kind of obviously a standalone thing, but uh it could easily be turned into a GBC module, although it wouldn't be super exciting since it's only one thing, but I was going to try and stack a bunch together so that they would like pass the ball off to each other.
Eric, that speeder set is the last set with the old mold. Oh, I see all the newer sets have the new mold with two different versions. One with the bestar shield and one without.
I see.
I guess I'll need to get the new one at some point, too. Uh, as long as they're not in super expensive sets. Oh, yeah. The Oh, yeah. The ATRT attack looks reasonable. It's not that big.
Well, the other ones are all in pretty big sets.
Okay. Well, I think that's about all I had planned for today.
Uh, maybe we'll just run the robot dreams as I sign off. We'll give it another run through. Hopefully, we don't have any ball drop issues.
I guess it'll be a good test to see.
We'll give you a nice shot of them all working.
But yeah, um hopefully I think I'll stream next week again. I don't unless something comes up. But uh yeah, thanks for everybody for joining.
mods as usual. Eric, Brian, R. Hamburg showed up for a bit. Uh yeah, and hopefully Sunday I'll uh put this through its paces and uh I'll probably shoot some video and post it on social media or something. Uh if anybody is curious, probably just an Instagram story, Facebook story of it working. But otherwise, we'll see you next week. We'll do something. Thanks for everybody for joining. As always, uh, hope you have a good week. Thanks for watching. Keep on building and we'll see you in the next one.
Heat. Heat.
Heat. Heat.
Heat. Heat.
