As a sequel to my earlier creation, Titan Mark I, I give you...
Titan Mark II
SO far, all I have is one arm. Not very impressive, you say?
Think again.
This single arm is the size of a teenager's arm. Its hand has four fingers and a thumb, with proportional lengths. It. Is. Amazing.

C&C appreciated.

Cool but I hope you realise you've set down a road that will lead you into spending tonnes of money on pieces and breaking all your fingers from popping ball joints.

Anyhow I'd like to see this once you've bulked it up ;3

Edit:
Also one pointer. I recently made a large bionicle which I can't take photos of cuz it won't fit on my windowsill. It's about 70cm long and weighs a huge amount. On that scale, the pieces of lego have a sort of ...sway.
This is to say that they jiggle around, if you try and wobble the model it begins to oscillate and even the slightest movement can send it tumbling down.

It took me four weeks of constant mechanical additions and intricate geared-up friction points to make my model stiff and firm for play.



YOU have a completely different problem because your lego model when finished will weigh a whole lot more - it's going to be a very difficult path for you.

I am fully aware.
Hopefully LEGO will add the HF ball joint pieces to the Pick-A-Brick wall...

Just wait until you get to the legs.

[Srakii~Pktaaim]

Oh the horror... *shudders*
Yeah, those are probably going to need, like, 10 HF titan legs (you know, the double ones).
I think I'm going to save that part for last.

I can only use my own model as reference here, let me tell you how I succeeded in making it stable (bear in mind that my model is probably only the length of the arm you've currently made, but it weighs a lot more because it's fully finished). My model was four legged.

Hip: The hip is attached to a Technic crane turn-table. There are three pop-joints immediately attached to the turn table that add a small amount of friction. One extra pop-joint is added on the outside of the turntable by a cog. The cog ratio means that this single pop joint provides more friction than 10 ordinary pop joints, so my advice is gear up!
That's just the rotational movement of the hip. The side to side movement is held by two pop-joints and the up and down movement is held by four pop-joints. In total both hips require 20 pop-joints.

The first joint in the leg requires two pop-joints and one friction pin. The next joint down requires three pop-joints, and the angle requires 2 pop joints for one plane of movement and another 2 for the other plane of movement. In total that's 38 pop-joints for both legs, not including toes.

The front legs are primarily connected by the shoulder by four pop-joints and 2 pop-joints respectively. This gives all but one rather unessential plane of movement. The elbows require two pop-joints and two friction pins each, any less and the model is less stable during play. The wrist only needs one ball joint thankfully. That brings the total to 44 pop-joints and 6 friction pins.

The tail is attached at the base by three pop-joints for one plane of movement and two friction pins for the up and down movement. Rotational movement is left out to keep stability. Each section of the tail requires one further pop-joint AND friction pin except for the last section. This brings the total to 50 ball joints and 11 friction pins.

The head was a challenge. It attaches to the base of the neck by one ball joint and one friction pin, then the neck attached to the body by another ball joint and two friction pins (these friction pins each require a ball joint to allow for rotational movement). This brings the total to 52 ball joints and 14 friction pins.
Edit: forgot waist, that's two extra friction pins


Add to this the complexity of including cog functions and you get how difficult it is to make large scale mocs stable. Anywho I think you've probably got the idea that I wouldn't mind helping on the technical side of building this moc if that's alright :3
Also I hope I scared you, because it is scary.

Nice! I've been thinking of doing something like this for a while, but never got around to it. I think the use of HF limbs as fingers is a good choice. Lots of articulation, not overly long.

I would recommend giving it some plating, if you can. Remember C-3PO in The Phantom Menace? Reminds me of that. If you've got any of the 2008 vehicles, the'd work (at least, I know the Axalara's got lots of good plating pieces).

EDIT: Darn that server, I would have been the first poster.

A life size bionicle? Toa are like 7 feet tall.
That said, its Karz'n amazing. It makes me want to make something like this. It looks a bit hollow with all the gaps, so as said above use some plating (or even some weapons/feet) to cover them up.
Whats the world record for the largest bionicle based creation?

I think the best big bionicle is this:



I honestly don't know who made it but grats to them

Looking cool, but WIP topics aren't for this forum, as said in the rules.
