    Default line follower

    hi im a polytechnic student who needs help bot line follower..tis is my final semester project..i din know the procedure to do a line follower..but i got specified a specific work for my robot...it will work like a line follower which will move on the line using IR sensor an d also moved by wheels...Now can any one help me to tell the the way to do it..

    Default hi

    phew....... i have read your post 5 times and still i am not clear what you want to say.......
    1) what specific work were you specified???? from my understanding of your post the specific task which your line follower have to do is to follow a line using sensor and move on wheels...... so whats special here?????
    2) i don't think there is any line follower which do not move on wheels ( or moved by wheels in your language :?: )
    3) you know the principle of line follower ( or the procedure to do a line follower :?: ) then what do you want to know about....... motors, control unit, sensor, wheels, power supply, mechanical design, or about the black line???????
    4) just type "line follower" on google and open first 4 sites..... you will get almost everything you want..... try and if you don't get what you want then ask clearly.......

    i only got 2 weeks to finish it..
    you are already running low on time..... and still you have managed to waste a day, just for saving few moments which you should have utilized for framing your problem in a better way........ that's not a good time management

    anyways, BEST OF LUCK..........

    well neway im a very stupid person...bt got high future thoughts..its ok if u wan me to search in google..i already got it..ya of coz my english broken..thanks to correct me..bt i realy din understand the schematic diagram..how to convert that schematic daiagram into pcb...
    can teach me ar??or u can give me ne line follower circuit

    please i need ur help..i noe time running low... sorry to interupt u all..just wana ask u all bcos im a indian..

    Default hi

    ok tell us what you don't understand..... also tell what you know so that we don't repeat it.....
    for your help ask yourself a few questions:
    1) do you know how to use a microcontroller(uc)?
    2) do you know how to write program for uc?
    3) how to put program in uc?
    4) how to use dc motor?
    5) speed control of dc motor using pwm?
    6) generate pwm using uc?
    7) using h-bridge?
    8) using ir sensor?
    9) how to detect the presence of line?
    10) how to turn using differential drive?
    11) how to solder?

    try out
    http://www.triindia.co.in/resources/?p=51
    that is primary concept of line follower
    than follow up this link
    http://www.triindia.co.in/resources/?p=39
    its construction details of line follower.
    you should hurry up.
    2 weeks is very little time for lf

    Visit http://www.societyofrobots.com/member_tutorials/node/59
    there is a step by step tutorial for building a simple microcontrollerless line follwer. So you will need no experience in microcontrollers or programming to build the robot.
    But the robot uses photoresistors to sense the presence of the line. You can replace it with IR sensors with little modification to the circuit.

    Well , dont confuse the lad, let him use comparators for making the lfr, not microcontroller, he has 2 weeks.. and if the primary function is just LFR, why do you want him to use microcontroller

    did you see:
    http://www.triindia.co.in/resources/?p=51
    or
    http://www.societyofrobots.com/member_tutorials/node/59
    both of them has a non microcontroller line follower.
    see them first and then tell if they prove to be helpful
