Cardboard box paper toddler.(version 2)
Cardboard box paper toddler.
Well, this did not work well. But it was quite fun to test.
It kind of works if one is careful. But as it is now it is way to flimsy. I will try some changes though to try and make it work better.
Materials needed:
1 stamp
2 servos
Wire
Cardboard box
Glue (hot melt)
(Just for fun. Not practical at all)

I made a small change so the toddler is more symmetrical.
Now, this works if one is very careful !
So now this project is finished.
(edit)Changed picture.

same as on a PC motherboard, so it would be easy for someone to find parts.

Elfa have 14pin connector and cable also.
It is a lot more stable design that uses the paper in a better way.
To transmit the servo power I use sewing thread(doubled if necessary) and a straw. Cut the straw to the right length. Tie the tread to the servo arm. Make a hole in the paper where you want the power to be applied. Thread the thread trough the straw and the paper. Tighten the tread and apply glue(on the paper and thread).
To fold the paper:
Place the “wellpapp” on a hard surface.
Use a ruler to compress the paper(corrugations) where you want to fold.
Required materials:
“Wellpapp” (corrugated cardboard)
Hot melt glue
Sewing tread (or similar)
Straw
Tape
If you want to take this further, I'll relay the following:
I have in my possession (but have not assembled) a couple of "paper" models. They use shirt board (or poster board) and then have you glue up the shapes to various thicknesses (laminations). They also have you glue up some shapes to simulate I beams, etc. to give more strength.
The weight might get heavier than your corrugated material, but you might also be able to get more strength.
In line with the balsa suggestion above, your local hobby shop may also have some very thing plywood that would work well, but some of this stuff isn't cheap.
You've got my mind going. I could probably use this type of construction to "sneek" my way into robots without my wife objecting....

It is a Toddler built with common materials that you can get at a Home Depot, Lowes, Ace, or your own house!
Even SHMBO laughed at it...
Quite a few times, when developing "paper" airplains I would take white glue, spread it super thin on a pice of 8X11 inch paper and set another sheet of paper on top... Because the glue was so thin, it set almost immedatly... I would do 3 or 4 and I got VERY strong paper (it wouldn't bend was a real pain to fold and cut)...
Anyway, your project is way cool...

I have also moved my battery packs on my Parallax Toddler to the legs in order to lower the center of gravity, but they really belong on the feet where they add real traction as well as stability.
If you want to go larger, a pair of stepper motors can easily be driven by a BasicStamp and provide more power than servos. Once could even do a plastic bin at the top , bamboo legs, and a pair of Nike's for feet. [noparse][[/noparse]Hmmm.... maybe I should try that].
Brass brasing rod is cheap for larger connecting rods [noparse][[/noparse]try a welding supply shop].
After that, add saddle bags for payload.
