Hi Gus...
Thanks for the answers.  I'm REALLY enjoying watching you build this.  Love the ribs.

Hi Jim,
Thanks for your comments. Two types of cable are used, a synthetic cord used by people stringing beads, and a nylon coated braided stainless steel line used by fishermen to prevent fish biting through it. (Both made in the US ) The cord is used where connections to moving parts need to be very flexible, yet strong. The stainless  is for connection from those points to the cams. Both are very strong, 20lbs break strength. 
A friend's wife has kindly offered to sew a suit for the politician, a great relief ! A series of ply "bones" flesh out the frame so clothes might fit properly. A pause now, in my work for this to be done, to be resumed for the cams and control mechanisms whenever that can continue.

1st my apologies. it appears ant edit will resend the message and I didn't want to load up members mail boxes with my ham handed attempts to correct the dumb double picyure post.

I do use the self healing and find they do work well. 

Automata.  The last one I completed was the Bill of Rights piece where I hacked together two Rob Ives pieces/mechanisms and additional art.  So I believe you have seen that. Previous to that they have been all hack pieces my GF and family enjoy, but aren't anything to show off. Often just a different slant on well known mechanisms. 

Since the Bill of Rights piece I've been trying different mechanisms, and it all, as I'm sure you know,  takes time that often has to be counted as "Lesson learned." So I decided to share a little of that hacking in paper before comitting to wood etc.

Hello Ron...
Thanks for posting.
Yes, it looks like paper, cardboard, and foam core are viable materials to work with.
The slot gears look interesting.
Do you happen to use a self-healing work surface?  And if so...do they really work?
Also, would love to see one of your completed automata if/when you have one that you would care to share.
Thanks again.

Old saying I was taught a long time ago: You can have any two: Good|Quick|Cheap| and I've often found myself trying to achieve a reasonable balance. In my experience, the value of your time is often the balancing point. So for those with out a complete shop, but have some petty basic tools, here's an example of cheap prototyping or even making a complete paper or composite automata.
Discount store foam board
Hot glue
Paper glue
"Tacky glue"
Heavy paper
Free gear templates (thanks Rob Ives!)
You can be surprised at "hacks" that can come to mind that are fun to throw together.
Scissors, hobby or snap knife, hole punch size of axle is nice but definitely not required.
So I'm playing with a paper automata and I want a second shaft. Power transmission by gears is always problematic with paper, if you look at a large number of modles,  most have one axle with one or more crank arms and a second linkage is usually a pivot of some type to work around the inherent flex.

Also, boxes are time consuming to mark out, print, cut and glue up, especially if it's a changing prototype.  The hot glue & foam box solves a lot of this problem, and is quickly and easily replaced if necessary. Made some bushings and attached them to the box with tacky glue so they can be repositioned, minimizing hole punches in the box. I've attached a couple of pictures,  two also showing how you can "eyeball" the shafts for perpendicular for best rotation and repositioning the paper as necessary.  For now, the outside of the gear axle is held with paper also attached with tacky glue. They will be replaced with more foam board when measurements are firmed up. All this because I stumbled across slot gears which provides a lot of leeway for the "Y" or in and out axis.
Hope this inspires some cheap fun automata.

Here is an image so you can get a feel for the size.  
Almost done...I still need to do some detail painting of the head.

Re: WIP "The Politician" Body Frame

 

Hi Gus...
Thanks for the images...and thanks for the notes on the images.  I know that notes take a bit of extra effort...they are appreciated.
Your politician looks sort of complicated!  Exciting!
Are the cables braided strands of plastic of some sort...or braided (or twisted) metal?
It looks substantial and interesting.
I look forward to seeing how you control everything (the cams).
Will the suit be rigid, or fabric?
Good job.
Thanks again for sharing.

Others are at the rear. The steel cables which will connect to the cams go below through the back of the feet. All movements have return springs, which means the cams are pull actioned via these cables.

What's on my bench: Peddler #1, just needs some paint now

 

Good evening...
Peddler #1 is what I call a product spinner.  I've spent the last week and a half worrying about the arm-waving mechanism.  I started with magnets in mind.  That didn't work.  Then activation by pins on the product turntable.  That didn't work.  Finally a cam and some linkages off of one of the three wheels...and I've got a Peddler that waves the way that I want.
As you look at this image you see:
  • The base.  It contains the electrics and does not move.
  • The drive frame: it contains the motor and the wave mechanism and holds the biped (and his unicycle) and it rotates.
  • The product turntable (the cream-colored platform to the right.  It rotates in a direction counter to the drive frame.
So now I need to finish painting the biped.  Then I need to create a video.  And then I need to get it out in public.
My next automata project will be working with the theme "All Lives Matter".  It's bumping around in my head right now.  It will be ready to be born when I've completed Peddler #1.
What's on your workbench?
Cheers from San Diego.
