 So using the hand to sort of be able to puppeteer these robotic constructions is pretty fun. It's very intuitive. It's a new form of control and you don't even have to learn anything or look at something. You enjoy the experience. It's almost like you have magical powers. So it gives that new feel in you that you are in Harry Potter world but you built the robot. There's a lot of research that has shown that if you build your constructions and if you are able to control them with your hands or with your body you start feeling that the construction is an extension of yourself.
