    Hello there,

    Hope someone might be able to point me in the right direction! Xsimulator helped me learn motion control for big robots which I turned into a company (www.see-it.tech).

    However, I've been pulled into a mini project to work on a motion simulator and have intercepted the UDP messages from the computer to the robot controllers.

    The simulator has two motors. One to turn left/right and one up/down.

    I can see UDP messages going from the computer to the robot controller via Wireshark. As example they seem to have a header and a footer. Then it seems to encode a value in binary that I've seen a top value of ~10,000. As example:

    00000000000000
    00000001100010
    00000110001010
    00001101110111
    000011000101001
    0000100110011110
    0001001011010000
    0001100010001011
    0001111100000101
    0010011000100110

    The data seems to be repeated 6 times every UDP message which seems a bit unusual...

    Can anybody point me in the right direction for material on how to understand the protocall?

    Additionally I can only seem to see one data stream when I should be seeing two. Any pointers??

    Thank you!

    DIY? As in it should be moved into a DIY section?

    I've gone through the UDP code a few times and will experiment with it next week, I'm just wondering if anyone has any tips in the interim.

    @SeatTime means is your work in relation to a commercial or DIY simulator, as it sounds like the former and if so the thread belongs n the commercial thread section.

    Please read the documentation about SimTools first. There is no need to intercept any UDP stream.
    You can send the data from SimTools to a controller (SMC, ARD, JRK, whatever) without the need of reading with Wireshark.
    If your controller is not supported, you can even build a proper interface yourself.

    Excellent, thank you so much for the pointer. This was exactly what I was looking for. Much appreciated :)

    Apologies Noorbeast for the double post and wrong group. Will learn from my mistakes :)
