    [GBC] The Akiyuki Project

    I have uploaded it on Bricksafe : https://bricksafe.com/files/Courbet/akiyuki-project/Steering_Cup_inventory.bsx

    I had this issue at the beginning of the tuning phase, when I was trying to run the motors with the regulator, without Mindstorms. At that time I feared the module would not work properly ever. With the Mindstorms program running the XL motor at full power (100%), the issue has disappeared although I did not do anything except programming the cycle and adjusting the height of the 2 touch sensors. Have you tried the module with Mindstorms only controlling the XL motor and a 4 steps loop (run XL forward - wait sensor 2 - run XL Backward - wait sensor 3) ? I still don't know if the purpose of the 2 linear actuators linked to the liftarms that hold the clamp is for rigidity only or if you are supposed to use them to bend the liftarms a little for a better grip of the clamp (I didn't). BTW, did you find mistakes in the building instructions?

    I deleted them by mistake, I have restored them now. But maybe the links on the front page should be deleted and the "train module type 2" should be removed from the Akiyuki Project since Akiyuki himself provided all the definitive building instructions for free and the .bsx files I provided don't match his instructions, and the fact that there is a dedicated thread about Akiyuki's GBC train elsewhere in this forum.

    Yes, the bsx file is an inventory file made with BrickStock. You should be able to upload it on Bricklink.

    Thank you Berthil and Juroen! @Berthil, I wish that you succeed in this "de-mindstormisation", but your module will surely be very different from the original one, I assure you ! It might be a good idea as Ankoku suggested to allow the spinners to rotate full circles, devicing a 4 phases module instead of a 8 phases one.

    For those interested, I have posted building instructions to Akiyuki's Container Transporter on the [GBC] Akiyuki project (EV3)(NXT) thread.

    Hi everyone, I present you complete building instructions for Akiyuki's Container Transporter (CT). This one has been long overdue. Links to pdf files (I had to split the BI in 3 files because of size consideration in Bricksafe) and inventory : https://bricksafe.com/files/Courbet/akiyuki-project/CT_GBC_part1_3.pdf https://bricksafe.com/files/Courbet/akiyuki-project/CT_GBC_part2_3.pdf https://bricksafe.com/files/Courbet/akiyuki-project/CT_GBC_part3_3.pdf https://bricksafe.com/files/Courbet/akiyuki-project/CT_GBC.bsx First a little disclaimer. I had told I would use Stud.io for this one, but I end up using LPub3D like before. I quickly realized starting on this software with a nearly three thousand parts project was a bit too much, so I thought I would only use it for generating instructions from a MLCad modelization. But first, the misrepresentation of the shock absorber parts in stud.io annoyed me a lot (there are 7 shock in the CT, including 4 Unimog ones, sadly...) and second when I changed the parameters of the level of restitution to something acceptable the software went on crashing again and again on my PC. Replicate the CT would not have been possible with Akiyuki's lone video and the 3 pictures from his 2015/03 post on his old blog. So I deeply thank him and @9v system too for the additionnal pictures unvailed recently. Crucial things were revealed, but not everything - thankfully! Where would be the fun in that case? I think I have been quite faithful in the end, except maybe for some structural parts and some aspects of the assembly around the XL motor. I have also tried not to use any part which was not available back in march 2015 ! The basics : 2873 parts, nearly 1 meter long, and very expensive to build (NXT, 3x Touch Sensors, one XL motor, 2x old 9V motors as well, 3x conversion 9V/NXT cables, 7x shocks, 4x linear actuators, 3x 16L axles...) As always with Akiyuki's modules, there are some very clever builds even if it's a Mindstorms controlled one and not an all mechanical one. The clamp and the 5 integrated clutches are notable. I won't provide the program directly but I provide the blueprint for a basic version in the third building instructions pdf file. It's not that difficult to understand how the module works and anyone can work around and adjust the settings as they please. For those who have not seen it already : Laurent

    To me it looks more like the magnet holder plate 30159

    Thanks Berthil! The whole thing is a 8 phases cycle, so it's complicated but @sawyer klegr did it, didn't he?

    It takes approximately 11 seconds for a cycle, and the lift can handle 11 balls at once so yes it might sustend the 1 ball per second rate. But it might be a little too much in the long run, especially for the scissor lift who will stop working if it's overloaded.

    Akiyuki could have designed his module with all the containers at the same level, but it would have necessited either a higher lift at the input or a longer lever arm for the clamp at the output, in both cases increasing the strain on the XL motor.

    Thank you! Feel free to ask anyway. There is a 1 stud level difference between each of the 3 fixed spinners (and also between the 2 height-adjustable ones) Thanks! Too bad there is not much left.

    Check out my video of Akiyuki's Container transporter. I have to say it's a relief that this module works better than I thought while building it. I spent a lot of time on the tuning phase, getting all the mecanisms to work properly. On the other hand programming the NXT was a breeze. I'll do a proper presentation when I publish building instructions. There is a lot to say about this module.

    There is nothing cyclic in the lift mecanism of the Container Transporter. A 4L liftarm rotates 90° to get things up, then rotates in the reverse direction to get things down. When the lift goes down, it compresses the yellow shock absorber which in turn helps the lift when it goes up. BTW the gears in the pictures are linked to the 4L liftarm. and if you turn them too far you break everything - no clutch at all...

    Indeed, but it was hopeless until @9v system brought Akiyuki's pictures. A little teaser:
