Dagu mini pan/tilt kit and another question

I'd like to try using the Dagu kit for another purpose (non-robotic) and I'm wondering what voltages I am supposed to feed the motors?  Also, to reverse motor direction, do I just reverse polarity?  I want to use the Dagu mount for a small camera (webcam).

 

I also have another question:  I need my camera to be able to increase/ decrease in altitude but without changing angle.  In other words, while the Dagu kit could take care of altitude via the tilt axis, I need tilt NOT to change angle, just go up and down.  Imagine a steady platform that goes up and down but does not tilt.  Is there something cheap and small that can do this?

 

Thank you,

Alf

The Dagu one will not do
The Dagu one will not do what you want at all.

I can think of several ways to do this. Can you do basic metalworking or do uyou have a 3d printer available?

The easiest way to DIY is to, as I see it, use a threaded rod as a linear actuator.

There is a mechanism with multiple beams that would keep the top level, and still allow panning if desired. There are several books available on mechanical mechanisms. I don’t have mine with me.

You may wish a delta arm

A delta robot arm would maintain z angle on the end effector, yet rotate and go up and down.  Search MeArm for more info.

The dagu mini driver is a good choice for driving servos or a robotic arm!
