The Hexaflex Toy

The Hexaflex Toy.
video
Allow me to introduce to you a new conceptual toy that will open up your imagination to build and shape three dimensional space.
All thanks to the guidance of Serendipity I have reverted back to using the Hexaflex matrix as an educational toy. This toy has all the potential to allow scientists, engineers and children to explore the world of natural engineering and to discover new relationships within Mother Nature's geometry.We are carbon life forms.Carbon forms the basic chain structure that allows biological molecules to achieve their complexity and versatility.
This new conceptual flexible toy emulates the geometry of how carbon atoms join together allowing us to make all the complex natural forms that can be found in the natural macro and nano-world.

Layers of Learning

The Hexaflex toy is a building kit. It is an educational toy that incorporates multiple layers of learning. These layers promote both critical thinking and discovery. 
These layers include:

1. Exploring the world of polyhedra.

2. Discovering the intricacies of Nanotechnology.

3. Creating robotic structures.

4. Integral construction possibilities with Lego.

The kit consists of a collection of flat hexagonal and rectangular tiles made from Nylon that can hinge together with one another. The tiles easily snap together and apart with an audible click. They can be assembled to construct such objects as multiple variable surface curvatures such as spheres, domes, buckyballs,
 nanotubes, torus /doughnuts, terraced planes, rhombic dodecahedrons and parabolic dish structures.

It is also possible to construct a specially designed latticework. This lattice has very novel properties. It is an assembly of an expandable/contractible truss mechanism (Nodlet)which creates a surface whose curvature can be manipulated remotely.The hinges are common throughout which allow an amazing freedom to build anything in nature.

Individual cells of the lattice can be independently opened or closed. Because of the increase in tension forces experienced in robotic applications, individual metal hinge pins can be inserted into the hinge barrel to prevent the hinge joints coming apart.
The tiles also feature bearing holes that accept Lego axle pins. This feature allows the Hexaflex Building Kit based on hexagonal geometry to integrate with Lego orthogonal structures.

Toroidal Armature

Toroidal Armature


The matrix shown in tubular form showing zig-zag, armchair and chiral.

I believe that Hexaflex can be used as a toroidal armature in order to hold the windings of a toroidal coil in a pre-ordained geometrically governed set of three spiral paths moving around the toroid.
One of these spirals is that of the Rodin coil.


Once the angle is chosen and set into the armature, two other winding paths are formed set at 120 degrees from the original spiral angle. I wonder what results three windings would create.

    I am amazed by the potentials of hexaflex. Have you ever made a torus with hexaflex? What would the 2D pattern look like? It's fascinating that channels would be available in a hexaflex torus. Perhaps the wires could be wrapped into these "venting channels"?

  2. Aloha Scott,
    Here you will see hexaflex rolled up into a tube.Now imagine joining the two ends of the tube to create a torus. So the 2d pattern is hexaflex as seen in my blog.
    Hope this helps.

  9. I have the same opinion with most of your points, but a few need to be discussed further, I will hold a small discussion with my partners and maybe I will ask you some opinion later.

  20. The problem with this trellis/lattice shown here is that a "tube torus" is the wrong model. The inner 'hole' should converge infinitely in the manner of a cone infinitely approaching/compressing to a point with smaller and smaller circles spaced smaller and smaller apart.
    Precise armature construction procedure outlined here http://vortexspace.org/display/glossary/Circle-Trellis+Construction+Procedure - Programmers needed to build an applet in LWJGL with either Xith3D or JME (java monkey engine).

Robotic Snake




















There was only one last large flat sheet of dural Hexaflex left out of 10 which had been laser cut.

I was scheduled to go onto our local TV station to talk about the invention. I really needed a smart, good-looking prop. The laminated card prototypes of earlier days had been handled so often that they were now falling apart. Okay ....shoulders to the wheel and all that...... so I went through the whole forming process again and made that last flat sheet into the largest expanse of Hexaflex so far made that had some spring in it that allowed it to stay mostly in a fully folded condition.





I rolled it up into a cylindrical shape and marvelled at the way that it lap jointed beautifully into the three different aspects of nanotube forming.




It reminded me of a snakeskin .


I researched "snakeskin" and discovered a thriving interest in making robot snakes. Ah! If only one could make a snake that could move like a snake instead of the ungainly efforts so far demonstrated by the state of the art.
 So now I think I've found the solution..... ABS was a good material for strength and the acrylic prototypes that were printed demonstrated a really rigid flexing that ABS would display. That was a problem to me, insofar as that it wasn't really emulating the flexibility that a sheet of hexaflex made from cardboard gave me. This was my technical summing up which described the situation:



"So now we have the finished CAD prototypes. They have been 3D printed in acrylic. They are fragile and break easily but the detail is fine and exact as it has a print layer thickness of 16 microns (0.00063”)
ABS requires a different method of printing called Fused Deposition Modelling. The prototypes have been designed to be made from ABS plastic which is much stronger than acrylic but unfortunately does not hold as much detail as it has a print layer thickness of 40 Microns (0.0016”)
This may cause a deterioration in the fine detail of the bump and hollow which give the tiles the ability to click together.
We have choices:
·        Make the bump and hollow bigger.
·        Remove the click factor altogether
·        Ignore and go to plastic injection molding and trust that the detail is going to inject exactly as CAD design
·        Change the material maybe a more flexible type. I’ve called Emil and he thinks that nylon would be perfect in terms of flexibility and hard wearing. It comes, I believe, with a 16 micron print layer thickness. Emil will get us a quote from Protomold.com. He has no supply as yet of  nylon…to do some experimental prints …..may take 3 weeks. This choice of materials may well be the answer to the flexibility that I’ve been looking for in the tiles. It’s worth the wait IMHO"

Everything seems to working out whether I realise it or not...lol
