    Hello everyone,
    This is my 1st post and my 1st sim. I wanted to know if the Arduino Uno would work as a controller for a 2/6dof platform, I am just not sure if it will work with x-sim I have never done any programing. The parts I am looking at so far is the uno for the controller and Critical Velocity 28A, 5.5-30V PWM Motor Speed Controller (High Frequency) and w-motors. To start i will build a 2dof to learn but i really want the 6dof Stewart but don't we all. :lol:
    Thanks for any help
    Pat

    my advice...start with simple project like 2DOF , servo gauge, gear indicator then move on bigger one. 6 DOF need bigger uController at least 6 hardware PWM. Which can produce about 15khz to 20khz each. 6DOF servo only use 50Hz refresh rate so its not necessary to use hardware PWM. Make your simple project with timer interrupt, play with PID. Good luck. :hi:

    nope im still here. :) my plan was to build a 2dof sim to play with first, just a real easy one. Then i have a bunch of old rc parts laying around so i wanted to do a model Stewart platform before i got the welder out and all my cash. im good with all the hardware pwm motors linkage fabrication all that stuff its just the basic programing if the controller. The uno has 6 pwm outputs and a usb input. I guess the real question is if i plug this controller in to my computer will it be able to run alll 6 motors or survo's in real time, is there a controller that i should use like the layout from Tronic i dont mind building a pcb. I just don't want to buy something to collect dust on a shelf.
    thanks for the input so far

    this is the description of the controller

    not matter 2 or 6 dof..there are big difference between servo purpose pwm and dc motor pwm. servo only use 50hz timebase .., DC motor like wiper motor use about 10khz-32khz. :yes:

    You should visit the Arduino forums and tutorials for help. There are a couple topics on this forum too that worth checking out.
