LEGO Technic Turbo Polyp / Kraken

[Shiva]

Good work!

An update.

Adjusting the arm connections

If the head goes up, the arms on one end will go up and the other remaines level to the original position.

My model needed adjustments on that. The lower arm dropped when the other arm on the other end goes up.

The model will be dressed up with groundplates, so the arms must never goes below the original position.

so now its good:

Transport

Also i am working on the transport of the model. On the real polyp the arms will be collaps so the ride can be transported:

So here is how my model will be on transport:

Left and right of the base there will be trailerparts that will be  connected to the center unit.

so i started to build those (in LDD, still in progress):

Will be continued...

Looking very nice! I love how much functionality you've managed to cram into this project

[kieran]

Only just seen this, amazing work. Can't believe how much you got into that model 

[Techniccrack]

Like money? i dont know, i do know the number of parts is around 14000

Ive done a little lifttest. The total weight of the arms with the crosses and new seats is 2500 grams.

No problem at all :)

I barely dare to ask it but... are you planning to make some kind of instructions when the project is finished?

Maybe i will.but its a big project.

I will think about it

[Techniccrack]

Maybe this will help a little. 

An cutted section of the lower drivesystem how it works:

Update:

Dressing up the middle structure

I dressed up the middle structure (top parts not yet)

Inside this middle structure is the box battery for the liftmotor. fits perfectly:

I choosed for making a little door for access the motor i case the motor is broken or to replace it, its very handy. 3 connectors and the motor can be replaced

Thank you for the progress pictures :)

[jwarner]

Looking very nice! The hatch is a lovely idea, and will surely save you some pain later on.

This is how the middle part looks in reality: https://3dwarehouse.sketchup.com/model/696bfac317c6d2974c73a472bff713a0/polyp-ocean-king-tunning-set

Would be great if you could add some sloped stones on top and on the bottom. It's a very straight cylinder right now.

Working on it:)

[wimpie3]

Fantastic!

[Edwin Korstanje]

Stunning progress, and have follow you on Lowlug. 

The time and effort you put in your build is amazing and hope that we stand both at LW Netherlands 2018 event and see you Turbo ployp in action.

How are you going to make the accordeon? Or are you going to leave the mechanism exposed?

I leave the mechanism exposed

[wimpie3]

What about using the plastic tube from a vacuum cleaner? :-)

[Techniccrack]

A tube like that doesnt fit. 

I will think about it how to do it. but leaving the mechanism exposed is also nice.

An video update!

This time stage 4 of the turbo spider.

New seats added, rotation drive train adjusted, rotating of the main cilinder, lifting, speed adjusting, stability and lowlevel check.

The rotating crosses i still working on. the 2 xl motors that drives the main cilinder are to weak. so there will be 4 xl motors that drives the cilinder, more power is needed to get this 6 kilogram machine get into full motion

Heres the video

enjoy!

 

[wimpie3]

Nice! It's a bit difficult to see but aren't the crosses a bit too high from the floor? They almost touch the floor on a real machine I think.

Thats a simple matter of adjusting the ground supports or lower the arms a little. no problem

[Techniccrack]

Video update

New test video with 2 rotating crosses.

For now just 2 crosses that spinning.

The drivetrain of these 2 crosses are connected tot the main cilinder.

The other arms will be connected to this "drive"arms, but thats for later:

enjoy!

 

[wimpie3]

Niiiiice!

Just discovered another difference. On a real machine, the middle section does not rotate. In your case it rotates the other way around. But I don't think that can be solved.

On the real model: The middle section DOES rotate , otherwise the head can not make the arms go up and down

Some polyps has a cover in front of the rotating section.

some has a visible rotating section:

Other models has a more different system:

Like i said earlier:

my model is a mixure of different types of Polyp machine.

Read the topic or do your homework before bring up again a "fail" in the model
