    Default autonomous traffic signboard recognition robot

    hi friends,
    Take a look at this robot

    Its an autonomous traffic signboard recognition robot which i did for my final year project. The vision module is written in java. If people are interested I will post the complete details the robo.

    With regds,
    Cheenu.

    Hey Cheenu!
    Great job, old boy!! Congratulations!!
    And nice of you to share your creation with others.

    You have used a night vision CMOS Camera, I think, with built-in IR illuminating diodes?

    Well, it may not be fully autonomous, since it has to be attached to the PC and works off the PC brain.
    Whatever, I say its a great job!!
    Too bad you finished College .....and good that you did too :!:

    Good Luck!

    hi docel,
    Thanks for ur wishes man....

    I will give an abstract idea of the system:
    The system has a wireless security cam which transmits the images captured to a wireless receiver which give data in RF format (the format given out by video casette players)
    This output is fed into the pc using TV tuner card...the live video is processed frame by frame by the software written in java...
    the software searches for traffic signboard signals like turn left or turn right, etc....when it identifies any such signals....it transmits the corresponding commands to the remote robot via the serial port (programmed in java) using RF circuits... there in the robot resides a RF receiver circuit which sends the data to the microcontroller (ATmega8)....the uc identifies the signals and controls the motors using the L293D chip...
    am really very sorry for the crude explanation...
    if anyone need me to elobrate on any topic just tell me ....

    and docel though the video is processed using a PC there is no human intervention inbetween....the software running on the PC is intelligent enough to identify what signal it is and responds correspondingly....
    and so its autonomous right.....

    and man am joining MSIT - Embedded Systems Engineering program from Carnegie Mellon University....so still college student...hee...heee..heee..

    bye,
    with Redgs,
    Cheenu....

    Nice cheenu!
    We have done the same thing for many robots. The only difference is that the TX was also homebrewed. One of them will post the details sometime.

    Well...The PC controls the motors- so......! Autonomy is to sense and control by itself.
    And double Congrats!!!
    Have fun at MSIT-CMU. Dont forget to use CMUCam too. But this will do : why not convert into a Person follower? It can follow, lets say- red Minis maybe :lol: :lol: :lol:

    hi docel,
    thanks for ur wishes man...
    ya will try to use CMUcams...and maybe if i do a person following robo(one that follows red minis) surely i will let u know....hee..hee...heee....(kidding)
