If you've been following my Instagram feed you'll have seen this character already. With halloween approaching fast I thought it was time to bring him to life.
My plan is to animatate Frankie by connecting him to a vertical rotating shaft on a Mesh Gear box then, using a horizontal cam profile on the box top, I plan to make his arms move up and down as he turns round. He actually looks pretty good just turning without any arm movements but the moving arms will hopefully add an extra dimension.
Keep checking back to see how he is progressing!
While I was working on the final layout of the Triceratops model the final prototype was sitting on the desk next to me. I kept picking it up and playing with it, looking at how the various joints worked. In the end I just wasn't satisfied with how the head moved. It just didn't have enough range of movement. I stopped the layout/colour process and went back to the prototype to see how it could be improved.
Here's what I came up with. Click on the image here to see an Instagram video of the improved neck joint in action.
The original model had the neck fixed to the body then a two axis joint inside the head . The new version has a second two axis joint inside the body. It makes the head much more flexible and, I think, it is a big improvement to the final model. Here is the new two link, two axis neck piece.
...and here it is fitted into the body.
The new joint gives a much wider range of movement and makes the Triceratops far more poseable.
So, part layouts to redo then the colour. Won't be long now.
Back to the Triceratops! With the aid of a small plastic reference model I've been working on the shape of the body. I've put together two sides from a sketched out shape.
The three spacers are all squares - different size squares obviously. They hold the body into roughly the right profile. I'll work on a top piece after I've put together the digital version.
With the body profile roughed out it's time to fit the head. The neck glues onto the body allowing the head to be poseable. I'll probably make the legs movable as well though these ones in the prototype are just glued on.
Next step will be to scan the body parts and put together a digital version of the body. I'm planning on scaling the body up in size by 10% to get the overall proportions looking right. Looking good so far!
Thanks to everyone who came came to my Try Paper Models course at Higham Hall today. I hope you enjoyed it as much as I did!
For those of you that missed it, we spent a fun day making the Agreeable Sheep and Running Dog models.
I'll be running another couple of courses in January.

I've remade the triceratops head 141% larger than before. The neck joint now fits perfectly inside and the head is a better size overall. Next step will be to rough out the body parts at a suitable size and start joining everything together.
I made a quick stop-motion video showing how the neck joint moves. I've uploaded the video to Instagram & Facebook but thought it was probably too short for YouTube so I've tried embeding the actual video file here. You may remember that I tried it embed a video a couple of years back with mixed results. I'm hoping that browsers have got better at complying with HTML standards over the years.
Please can you let me know if you can see the video below. If you can't see the embedded video you can view the original Instagram video by clicking on this link.
