Yeah one big gray mess that I hardly know how to make sense of so lol - nobody look at me for the right answers. I might actually take up doing molds for the faces of dolls that I would like to learn how to robotically operate and do a series on steemit with tutorials.. So my opinion is completely bias because hey... this will probably be a market I dabble in and these types of people might be my clientele if I ever get good at it. So I am awaiting the Chobits revolution over here hoping to break into a fresh new feild that not a lot of people are in yet. lol (I'll most likely stick to painting)

Take a look at this :

This is the humming bird robotic kit.

Maybe is the sort of thing you would like to know. The logic is almost the same: "muscles" being operated by a computer.

Ok now I wanna try that. Hands would be a really nice starter coarse. Print out each one of the phalanges. Place the kit along the 3D printed bones and then make a hand skin prosthetic over top somehow- to hide the wires. That would be a fun project. I would try it.
