I have a new X6 Tarot build and so far the early flights are going well. I now look at the gimball and camera mount.
I should first clarify that my goal is aerial still photography with a full size Canon camera. That means that stable video is out of scope. Tilt control is and stabilization is a nice to have (2D).
While I was researching my purchases I came upon the Tarot Rabbit Invincible 2D full size gimbal (sounds like a winner).
I should have realized it was too good to be true. I like the build and the look but the description (which is unintelligible, doesn't meantion how to control it.
It uses a belt drive and continuous (360) servo motors). I have no idea how to control these from my Pixhawk.
Issues:
1) Direct control using the servo option in the gimbal panel in Mission Control will not work with 360 servos. The PX outputs an angle and that translates to a rotation speed. Not very useful.
2) Replacing the servos with "standar" servos (the ones in the gimbal are normal size) will work, but will only give me a rotation of 45 degrees due to the 4:1 belt drive. Not very useful.
What would you do?
1) I have a smaller brushless gimbal I build (as much to learn as to use) and it uses a STORM32 controller. Is there a way to get the STORM32 to control servos? I realize it will be slow but it will be strong and I can manage the tilt. Dum idea?
2) Hack the gimbal to accept brushless motors - any idea what rating of BL motors I need to a 1.36g camera?
3) Stop dicking around and go buy a proper gimbal and start taking photos. A full size servo gimbal would work fine.
cheers
