New ArduCopter Accessory - Tilt/Roll Cam Mount

For those of you who use a camera on ArduCopter there's a new accessory being added to the store today. It's a til-roll camera mount that stabilizes small cameras (up to about 75 grams) and keeps the image straight up and down while ArduCopter is maneuvering to maintain position and orientation. The kit is $20 and can be found here. Please note that the kit does not include a camera or servos! We recommend you use HS-55 servos or any other sub-micro servo in the same size. The kit does work out of the box with ArduCopter code - plug the servos in to channels 5 and 6 for automatic stabilization. Happy flying!

Looks good! Can you tell us more about how this is optimized for ArduCopter, compared to all the other pan/tilt gimbals out there?

The biggest difference is that it's a roll-tilt stabilizer so it will keep the video image vertical while the quad is flying sideways as well as forward & backward. It does not pan back and forth - we can get that same movement by re-orienting the quad since we can fly in any direction. It also mounts easily onto the ArduCopter frame with a few included screws though you will need to drill 2 or 3 holes depending on where you decide to mount it.

Sorry - it does NOT need any new holes to be drilled. It fits right into the stock holes on ArduCopter :)

What are the maximum tilt/rolls angles of rotation?

It would be better to use some servo with metal gear for tilt. Otherwise you would be forced to change it every time copter lands harder.

The hs-55 are available with both plastic and metal gears.

Comment by Jeff Taylor on August 12, 2011 at 12:34pm

The gears are 1:1 ratio so a 90* servo like we are using gives you 90* of travel - so up to 45* each direction.

 

Metal gears are definitely something to consider but the way the tilting arm attaches to the servo will allow it to twist down free of the servo gears if you land hard. Even with a little CA glue attaching the arm to the servo I think that part will come free before the gears strip. I'm doing fine on Nylon gears so far.

Agreed: Video please!

This is very cool. Will there be code that stabilizes the roll angle using gyro input, or will it be manual adjust? I've always wondered how much any inherent jerkiness or slop in the servos (they all have it no matter how good) affects image quality.

The code automatically adjusts the roll and tilt angles as the quadcopter moves. You just have to make sure your servos are centered in the angle you want the camera to point as you assemble it.
