Robotics doesn't seem very useful as a major , agree or disagree

  1. Apr 19, 2010 #1
    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?

    Why do you think a robot has to look like a human?

    Industrial robots are very common and useful. Generally they simply consist of an arm which is fitted with an "end effector" to perform a specific task.

    So robotic just means that it moves, not that it looks humanoid?

    'Robot' is a word which comes from the Polish, meaning 'Slave worker', I believe.
    There is no need for it to be an Android - just to perform some task.
    Making your average robot, an Android would be to introduce pointless complexity and cost.

    I used to program unmanned stacker cranes. These were cranes that received a command from another computer to store or retrieve a pallet of material at or from a specified location in a warehouse. Some people called those cranes robots.

    It seems to me that a robot in human form would have limited usefulness because it would be duplicating what humans already do. The advantage of robots is to be able to do things humans can't do and it seems to me many times that requires a different size or shape.

    You might want to look into "controls" and/or "mechatronics", the subject of robotics gets talked about is lots of EE and ME courses and is a big field that is not likely go to away. If you know some PLC programming, control theory, and some other ME stuff there are TONS of companies that do automation for industrial applications and other stuff that you could work for. If you really want to get into the humanoid robotics you can get a masters or PHD and go into research on these types of areas, I don't know the name of it but there is a whole field dedicated to human like robots. I would suggest you start, however, with choosing between ME and EE (you can do both but that is a TON of work and will take more years in school at most places), once you figure that out you usually have 2 years before you have to choose a specialty and can use that time to get more familiar with what is out there. Good luck!
