The chicken bone robot prototype I made turned out pretty well, mostly because bones have kind of gone through millions of years of evolution to be as strong and light as possible. Sounds like an ideal limb material. It’s also really nice to work with. Would be nice to do some composites too, for molding and 3D printing etc. from egg shells and feathers (2.3 million tonnes of EU feather waste from slaughterhouses a year) and whatever else.
egg shells + calcium carbonate a la Little Pink Maker
