a circuitry design does not really have to be similar to human form (i.e. a robotic like thing) in order to be useful. So majoring in robotics does not seem that important? Just plain engineering (mechanical or electrical) is just as useful if not more. agree or disagree? also if you read the book "build your own humanoid robot" by Karl Williams , it makes sence that an application does not need to look human to perform a particular function? or to be useful? can anyone give an examples of when it absolutely has to resemble a humanoid form to be useful? other than frivolous things like a human like robot carrying a tray to your room just like on the Jetsons, which again would not be necessary, it would be able to carry the tray to the room without looking humanoid just fine. another example would be this robot in Asia teaching students in a class room, http://www.telegraph.co.uk/technolo...her-conducts-first-class-in-Tokyo-school.html but again it doesn't need to look human to serve it's purpose, so how is robotics useful?
