40mm retractable camera turret

Posted by UAS_Pilot on March 12, 2012 at 10:00am

I think that we need to restart the blog on this. 

This guy built a 40 mm ball turret that would work great in small UAS's. He said that he would not sell it but i think having him post details of how he built would be nice.

Here is a video of tit working.

If anyone has other turret systems to share of Pan and tilt systems please post... I am looking for a good design to integrate into my UAS...

    We had a retractable camera system in the AeroSonde UAV we flew.  I can tell you from from personal experience, stay away from the pulley idea.  They are delicate and will jam.  Please note, the bird was HIGHLY developed and it still failed.

    I like the new design. I sure does have mor moving parts. Do you think this might cause problem later down the road?

    I would love to see one complete.

    Great work.

    @Monroe please do..! I'm waiting with baited breath ;)

    I would suggest some sort of gear or pulley system to even out the preasure of raising it and lowering it. 

    also you might want to think about maybe a spring tension system that might always press on the other side? 

    You could even relocate the lift point to the center of the load?

    keep us informed of the progress.

    Interesting design.  But I don't think the retraction mechanism will work unless you use some expensive linear bearings on those posts, or use two servos.  It will just jam soon as the one side lifts and it gets cocked on those posts.

    @Shane,

    I like the design. It is a simple approach to a problem.. I has a very low part count and minimum moving part. 

    If I ma sugest 2 things. 

    1: Flipthe pan servo over so theta the output shaft is pointing downward so that you might get more down motion when extended.

    2: Add som type of compression support on the other side of the assembly so that it tracks up and down on the guide poles evenly. (you could even put 2 micro servos one on each side) 

    Other then that awesome design. I like where you are going with this and I would love to see it in reality...

    I have full access to a laser cutter and can contribute to this effort.

    How would i set up software limits in ardupilot for the pan and tilt servos if they are continuos rotation servos. 

    Thanks for all the help.

    Here is my final set up for now... I went to servo city.com and for under a hundred dollars I have a simple system. When completed i will have 180 deg pan in both directions and 180 deg. in tilt if needed.
