    Hy I'm Mohamed and I'm studying electronics engineering and i wanna do my project after 2 years as a Robot plz.
    i wanna members here tell me what i should read and do to reach that thing
    should i begin firstly with micro controlling OR WAT I SHOULD READ AND LEARN BEFORE DOING THAT?

    Personally, i think you have to learn programming microprocessors as to know what they are able to do. Then study about various kinds of sensors which can be used for the robot. Finally, you should learn some mechanisms the robots use to move and combine your knowledge about microcontrollers and sensors to make your project.

    Form follows function. You'll need to decide what you want your robot does before putting anything down on paper.

    One step at a time - how large will the robot spider be, and how do you propose to move the legs?

    How much time do you have? I'm a big believer of a bunch of baby steps on stuff like this. You can get help by reading sources about other peoples robots (and you should), but getting hands on experience is really good for your engineering education.

    First you need to play with a microcontroller enough to understand how to get it working at a very basic level, like blinking an led. Then you need to learn how to run a motor with it. This will require some external circuitry as well. After this, you will know what you can and cannot easily do, so you start to put together the plan for the full robot.

    Or...you could just try to jump in the deep end and build it from scratch. It probably won't work at first (if ever) and will be frustrating to try to debug (if possible at all).

    You might also want to spend a couple days studying spiders, how they move, and how they hold their prey. Pay special attention to legs, chelicerae, and pedipalps. Videos of movement will help a lot. Watching actual spiders will help even more.

    Plan to spend either lots of money or lots of machine-shop time.

    I hope you get a lot further along with your spider-bot than I did with mine. My prototype was made from wood, due to easier shaping of the joints. Darn thing almost walked. Almost.:rolleyes:

    The funny thing is, a lot of this work has been done, in the form of toys! My boy has several IR RC toys based on insects and arachnid. Another source to look toward for inspiration.

    I was Googling (is that a proper verb these days?) to see if
    Heiserman's Building Your Own Working Robot (Tab Books, 1977) is still available. It is out of print, but used copies are available. While searching, I ran across this: Insectronics: Build Your Own Walking Robot by Karl Williams ISBN: 0071412417

    that sounds interesting, all i know so far in my studies is about logic gates, amplifiers, etc. I don't know much about microprocessor or how to write a program and execute it.
