I'm currently trying to build some motion control kit for video production using large RED cameras. These would weigh between 5-10kg. I posted another thread about a slider, which you can find below, but here I wanted to pick some brains about building a rotating device. Advice for heavy duty motorised video equipment Essentially, I'd like to build 3 small rotating platforms. These platforms could then be used individually to rotate products, small sets, joined together to rotate items in more complex ways (imagine moving a watch in two different axes), and joined together to form a pan and tilt head for the camera like the link below. Stage R: Rotary Pan and Tilt Bundle with Stepper Motors (add on) I can't see anything on Openbuilds that would work but I spoke with someone at Igus who said the link below would be perfect. It will provide all the torque I need, more than I need, and can be rigged up in lots of ways: robolink® D robot joint, size 20, symmetrical It sounds perfect but it's expensive and I wondered if anyone can think of another solution. Thanks in advance for any advice you can give.
