Thread: Robot vision

  1. #1

    Default Robot vision

    Can anyone guide me as to how I can invove vision in my robot. The robot has to be a complete standalone system and has to identify objects of different colours and collect them.(image processing is also required)

    Also, which microprocessor should I use?? As far as I feel, a lot memory will be required.

    Pleease Hellp!!

    A 8bit uC based image processing system is actually not possible ( they dont have the muscle nor the resources ). Though things like AVRCAM and CMUCAM are availible they will require a little high end uC for the job.

    Though u can somehow get hold of an ARM with linux running which can access some cam etc.

    Best is to go in for a SBC / ITX with OS of your choice running.And plugin a simple cheap webcam.

    BTW CMOS sensors cost about 20 $ upwards ( the ones used in AVRCAM etc )

    I searched a bit and found that a mini ITX costs about Rs.8000-9000(149 euros).
    Can I get something cheaper for the same job?


    If I see the overall cost of making the vision based robot, will it be economical as compared to other options.(like blackfin,ARM)?Will the use of Blackfin/ARM cost more or less?

    I want to use linux only since it is an opensource OS.

    I am totally confused because I have never worked on any of these .Also, I am not getting their applications(on vision or image processing) on the net.
    Can you tell me something more about the ITX or provide some link?

    Thank you.

    Gumstix is quite cool and easy to work with ( i have done a project on it ).

    Other than Aerial /lightweight robot i wont recommend it.

    Whatever you can compile on linux will run on gumstix (so OpenCV will 2 ).

    Gumstix has a few disadvantages though - Its meant for embedded/mobile apps and some of the featues of the PXA255 have limited due to the form factor. Also ull have to buy expansion board/MEGA based extended IO board so itll come out the same price.

    Plus Gumstix has a client USB not a Host like ITX so now cheap webcams/BT or any such easily availible modules.

    So unless you are planning something really small/aerial dont go for gumstix(similar formfactor boards ).

    There are no size restrictions and it has to be ground based.

    To say, I am reallly new to all these thigs and thats why so confused.
    Should I use ITX then? And how do I select which one?

    Is it available in delhi or anywhere in india?
