timelapse pan and tilt was created by nastra
Hi,
I am interested in using Roboteq's controllers for a pan and tilt camera setup i am developing. I just have a few questions about the flexibility of the parameters. I want to be able to very slow operations. Such as timelapse. So for example half a revolution = a couple of hours, or maybe longer (as well as shorter) also we need a nice acceleration ramp either side of the move.
Is this possible with these products?

The controller could work for what you want to do, but you will need a very large gearbox to reduce the output speed of the motor to very low. You could use the controller to apply just enough voltage to keep the motor turning. You could also use an encoder on the output shaft of the motor before the gearbox, to tell controller that the motor is turning, and use it to maintain a very slow speed. It would probably be easier to use a stepper motor that had a built in gear-reducer to achieve what you need. You would just tell some kind of microcontroller to pulse the stepper driver every so often. -Adam
