IRIS Tarot Gimbal Users

Posted by AKRCGUY on March 17, 2014 at 11:00am

I'm looking for feedback from other IRIS user who have installed the Tarot gimbal avaialable as an option when ordereing your IRIS.  Some of the things I have noticed are:

1. Gimbal does not level all the way, slightly tilted.

2. Poor performance (Jello, etc.) when compared to other quads I've flown with same gimbal set-up.

3. Your experiences?

Please add your gimbal videos ro issues here so we can compile.  Thanks!

      Iris is much more laterally responsive with the new PIDs.

      Maintaining altitude is still tough.

      Cool, I loaded the params.. Do I have to write it or something or just load it from mandatory ?

       

      Too windy to fly today to test.

      Yes after loading or manually changing parameters in Mission Planner, write them to the Iris.

      You may want to then do a refresh and check that everything is the same. Any time you use the little drop down box to pick a parameter file to load and then write, you'll get a pop up showing any delta between your current and new params.

    If you are flying the Tarot on an Iris, you might get better results if you disconnect the Roll wire (red) and leave that input open.

      We'll give that a try.

    I been having the same problem too.

    Put some liquid electrical tape on the +ve and -ve wires where they join the board. Ive had two smokes/shorts and i finally worked out why. The exposed wire on my setup is greater than the distance between both solder blobs and sometimes they crooss and bang a short. Lucky for me this happened on the ground but im surprised nobody else had the same problem given its a fault in the manufacturing process.

      mP1- Yes we hot glue the connections to beef up the joint and protect it.

    I had the identical trouble when I attempted to bind a Spektrum remote antenna to the Pixhawk from an AR10000 receiver. When that didn't work out I put it all back together and reloaded the Pixhawk firmware.

    The gimbal acted as you describe only some 30 degrees from horizontal. When exploring a solution, it appeared that each time I calibrated the accelerometers in the Pixhawk the gimbal would find the horizontal position until the power was cycled.

    I tried the Tarot dongle to connect with the gimbal control board with the intention of reloading firmware 1.4, (by the way, I use a Window 7 VM on a new MacPro) and the Tarot Windows software would terminate in an error immediately after the program launched.

    Looking at the Pixhak setup in APM Planner 2.0, I set the tilt to channel 6 and 9 as the online manual (http://copter.ardupilot.com/wiki/common-tarot-gimbal/) indicated. The gimbal tilt worked as expected. However it wasn't until I pushed the "Stabilize Pan" (US spelling) checkbox that the GoPro locked on the horizon through power cycles.

    Good luck.
