This is my review of the book (build your own humanoid robots). I like this book overall. My only complaints with it are that it doesn’t use things like Arduinos, instead it uses DIY PIC micro-controllers and that it doesn’t show you how to make a finished humanoid. It only shows you how to make different parts which you have to figure out how to connect to make a finished robot, but you could say that is all in the spirit of hacking. 😉
