[GBC] The Akiyuki Project (2010 - 2020)

[Ankoku]

@9v system I have looked at that video of the Invisible lift many times and have commented about it on this thread. The extra motor being a key aspect of that.

Did just come across this:
http://www.legoengineering.com/meet-the-creator-akiyuki-kawaguchi/

Which has a image of the Ball Factory V2

Some interesting gearing changes.

Not sure I agree with these modules being in the "Inspired by Akiyuki" section of the front page:
Pasillos/ Tilting ladder
Serpentine
Ball Counter
Double Bucket GBC

I don't see using an Akiyuki hopper or off ramp as being inspired by. They are just using something he created in a very basic sense. None of them are particularly complex or innovative either. Nice, but not Akiyuki level.

Ball Factory V3 and the Berthil Cup-to-Cup on the other hand I 100% agree with.

[Ankoku]

So, I am going through and adding all the upgrade Akiyuki did forever ago and I weirdly just didn't really see.

I am trying to work out what is going on here.

What are those bricks down there doing?

it looks like they support the grey bevel gear housing to stop it moving around. you can see the one next to it also has one, i think its a 1x5 L liftarm in between those two 1x4 technic bricks

Another view of it!

greetings all,

i have recently been testing these colorful GBC balls in my Akiyuki modules, and so far they have worked great in

invisible lift, ball factory, zig zag lift, tilted rotors, cup to cup, stuck ball lifter.

they are slightly smaller then the lego balls which i thought was going to affect the performance of some modules but it looks like its ok.

i dont have strain wave or cycloid so i cant test them in these modules.

heres a link to where i got them from. they are very affordable https://www.aliexpress.com/item/1005002436311103.html?spm=a2g0s.9042311.0.0.5eb74c4dwW70MJ

I wonder why there is no new module from the master for a long time. Hope he hasnt lost his interested in the GBC thing.

same, im waiting for his next masterpiece, i still have quite a few other modules of his i need to build too or should i say rebuild

A lot of peoples habits have changed due to Covid-19.

So I have rendered up the new gearing.

Just gotta work out how the gearing goes within the bit with the long Technic Bricks.

very nice, i was able to replicate this gearing on my red version of the ball factory some years ago, from memory, i used a 12 tooth black bevel and an tan bevel in the gap bettween the two technic bricks

[Ankoku]

This is what I have gone for:

[9v system]

@Ankoku looks good, are you going to do the knob wheel drive as well?

[9v system]

@Ankoku is it ok if i add your improved cup to cup to the front page?

[Ankoku]

@9v system It is okay. I will add the cup-to-cup.

Not sure about the knob wheel drive. Probably, doesn't look difficult. I am guessing there is no syncing issues there really and a level of torque he is worried about. It is low on my priority list at the moment.

I am currently trying to redesign the spiral lift a bit. e.g. there are lots of elements about it which I don't like and it doesn't run very smoothly.

I have changed it from 4x 11L ribbed tubes, to 3x 12L tubes. The more recent 12L tubes are a lot softer. Also resigning the gearing underneath, as having gears sitting on Technic plates never feels like a good idea for smoothness.
Currently, it looks like this:

Clunky, but for now, it will do. Haven't got the bits yet, so I don't know if the design is a goer, but the 2x2 with the yellow connector works well.
Where the 1x2 plates are, is where the hopper for the spiral lift connects. Which keeps the 1x7L thin liftarm in place. Also supports the hopper better.

My only concern right now, is that if the spiral lift rotates too fast, the balls fly off :P

At some point down the line, I will redesign the hopper, so balls don't get stuck.

i have photos from akiyuki of the spiral drive gearing if your interested

@9v system From the ball factory?

yep

[Ankoku]

@9v system Is it on your BrickSafe? Also, is it any different to the instructions which are out there?

yes, i have it uploaded on my bricksafe somewhere, it is quite different to the instructions gearing

[9v system]

@Ankoku should i add the steering cup module here? it has the akiyuki standard on it

[Ankoku]

@9v system To be honest, for that sort of thing, I would be happier if we started to make the General GBC thread like this one on the front page. e.g. an image, links to instructions, part lists etc. Then we have one place for random GBC and another for Akiyuki stuff.

Would make for 2 really good resources on here.

Are you sure? All I can see is the mega plant.

[9v system]

has anyone here built the strain wave gearing module?

whats the most difficult part of it? its the only module i have not built, but i have just started ordering parts for it

it looks like making sure everything is free from friction is a challenge

[tismabrick]

I built this module. At first with the instruction provided here. But on an exhibition it stoped working due to too much friction. @dunes then posted a solution with two L motors. I modified mine in that way and it works flawlessly since then.

I have built it with 2x XL motors. runs really smooth.

 

[tismabrick]

Now I remember, it was the version of @dunes I built.
