Thread: More Mule then Rover?

    Re: More Mule then Rover?

    Now you just need a wireless camera

    The Mule has a 3meg webcam that I'm working on, with the netbook wifi connected to the house
    PC(laptop) and running a webcam there is a very large lag time in commands to the Mule, without the
    cam running the lag is not present, working on that soon, most everything I'v worked on lately to
    get ready for the snow was machination, wheels,weight,plow,weatherproofing.. etc..

    As is I can sit at the kitchen table with my laptop so I can keep an eye on it at all times

    If the webcam is loading the PC more than 80%, try adjusting the priority of the webcam process and your command/control process. Increase the priority of the process receiving/processing commands and/or decrease the priority of the webcam process.

    Is it that, or because everything is running through a single USB hub?
    1) Analog Output for the drives, and digital I/Os (limit switches, and switching)
    2) Phidgets 3/3/3 for feedback(digital compass, gyro, acc)
    3) Phidgets High Speed Encoder card for feedback
    4) Webcam

    I now have a US Digital USB4 to replace the Analog Output, I/O and High Speed counter with a single unit
    but have not install yet.

    You were right, seems by reducing the sampling rate of the gyro(was 10 msec, now 100 msec) the problem is gone(Sweet!, and Thanks!)

    But, while doing the plowing in video below the Mule sheared a bolt that held the wheel hub to the drive
    axle, causing one wheel to stop turning(what a drag). replaced single 1/4-20 bolt with two harden steel .25" dowel pins.

    Life is Sweet!

    Today my mom got a chance to play with the Mule, she said she like it and would use it, once I fix the depth perception issue.

    Shouldn't be too hard.

    Glad to see you're getting the kinks ironed out. That's a cool little remote plow you have there.

    If I put a snorkel on the Mule, it could now be an ROV

    once I fix the depth perception issue.
    Putting a camera up by the upper headlight facing down over the plow
    fixes the depth perception problem.

    jdolecki, that storm spanked the mule.
