Tchebyshev Plantigrade Machine

Just for fun, I made this walking frame based on the work of Tchebyshev who made it before any motive force other than animal effort.

The layout above is for one half of the machine. Build two lots and assemble using the sets of tiny screws you can buy "off t'internet" in batches of 1000 of various sizes for a few pounds. They come in a white plastic "orange-segment" type storage box with a rotating transparent lid having a single-segment slot for access.

Motors: "planetary gearbox motor" on an internet auction/sale site
Screws: "1000pcs Screw Set Glasses Mobile Phone" ditto
You'll probably need to thin-down a very small screwdriver/spinner to drive them home
