Lego

Here is a quick model I constructed with LEGO just to show how the whole mechanism works. its big, bulky and constrained by the dimensions of lego and peices on hand, but you get the idea.

I hope to use the lego worm gear, as it is pretty sturdy. All the other gears / arms will be done on the lasercutter [hopefully] and will be a much more compact / efficient unit. there will also be four, perhaps six arms - as many as I can fit onto the worm gear...
