Thread: First time getting PhantomX Turret + ArbotiX Going

  1. First time getting PhantomX Turret + ArbotiX Going


    I'm new to both the ArbotiX and Dynamixel components. I'm well versed in Atmel chips and general programming.

    I constructed my PhantomX board and I'm looking to just test everything then write a simple python server that can control the turret for me. I'm using the script to test basic functionality / movement. I am currently unable to get the actuators to move.

    Here is what I get:

    ./ /dev/tty.usbserial-A400C242 -1
    Digital: -1
    Here is what I've troubleshooted
    • Power is on and LED is lit
    • FTDI wire is correct orientation (tried both orientations, command fails on both, status light only flickers with correct orientation)
    • Power jumper set for VIN
    • J1 Jumper set to tie RX/TX, although I also tried toggling it.
    • Tried changing order of cables into Dynamixel
    I can not confirm that the Comm_EXT firmware is loaded onto my ArbotiX board but this is what the turret manual says. I see the same output from when the FTDI cable is connected to the ArtbotiX and when it is disconnected.

    Does anyone have any ideas? I can burn the Comm_EXT if necessary, I assume this is CommExt.pde.

    Commander Firmware was not loaded despite manual claims, had to compile and load. Works now.

    Trossen stopped uploading firmware some time ago I believe. The product page has been updated, but the manual is still out of date. I'm sure they'll get it updated soon.

    I'm a complete green horn when it comes to programing, but I like to learn new things and try and figure things out. I got a dumb question I'm hoping someone could help point me in the right direction.

    I have a Phantom X Robot Turret, and I was wonder if I should load the Comm_EXT Proportional sketch onto the Arobotix board before trying to setup control using Roborealm?

    Listed below is my hardware/software setup:

    Windows 7 64 bit
    Arduino 0018
    Python 2.7.3
    PhantomX-Robot Turret with 2 each AX-12A servos
    ArbotiX robocontroller - FTDI usb cable

    Thanks for the help.

    you upload the CommExt applet

    Is there GUI software available that emulates the Arbotix Commander?
