I saw this “Popsicle Bug” robot on this website. I was very inspired by it and wanted to make one of my own. It reminded me of my old lego projects that I did in college. Except this was very light weight. The original maker left it very organic which is what I wanted to do and its fairly inexpensive to make. I used regular thread from my wife’s stitching box instead of a fish line. You can pretty much use any string/thread thats strong enough to handle the tension.
