 Bigger Bigger  Smaller Smaller  Reset Reset

I want to mount one stepper motor on top of another for a pan-tilt camera system.

I have scoured the net for a vendor of these items but can't find one. I have found universal mounting hubs for stepper motors but no brackets to attach to it.

Is there any online sources anybody could recommend?

Thanks,

Calum

Any particular size of stepper motor?  There are various mounting brackets on
sale for CNC machines (normally to make room for couplers to the leadscrew), some
of which are box-shaped and might be suitable.

I want to attach a camera to this system - a DSLR or a standard size camcorder.

I would imagine that I would need reasonably standard size stepper motor for such a system.

Additionally, what is CNC?

start with e-bay
search for pan and tilt.

you can purchase camera ready devices.



CNC is computer numerical control.

Google search for "pan tilt stepper bracket" - take a look at the results and images; for instance, here's a link to a rendering of such a potential system:

Note the use of belts and pulleys for gear-reduction; this will likely be needed by your system because many steppers won't have the power to rotate the mass of the gimbal mounts and camera on their own. Of course, there are other options for gear-reduction; belts and pulleys are just one possibility.

Building your own stepper-motor based pan/tilt mount is not an easy task (compared to one using servos), but can be done by a hobbyist. If you need repeatability in positioning, you will likely also need to incorporate a feedback mechanism into the system (potentiometers or other position sensing devices to monitor the angles). This will of course increase the complexity of the system.

I have made a few of these out of wood.
Don't need the belts if you don't get wild with the speed.
Just put the motors where the large pulley is.
Can use servos or steppers.
Simple to make with basic skills.

Actually you can do just that. One servo pointing up with a disc on the shaft. Other servo on it's side on the disc. Put a plate on the 2nd servo, and mount your camera to it.
