Hi Everybody..
With robot mounted vision sensor, I am trying to get the robot position synchronized with the sensor measurement...
The idea is create a system which can work with any robot ...
One solution could be to trigger the sensor at each point of the interpolation points and with some further processing we could get the exact robot position exactly at the sensor trigger time..
The question is how to get the interpolation points? with KUKA they can be accessed using RSI but i mean in general.. :help:

I don't think there's any universal way to do this -- some robot brands, like Universal (hah hah) can't support it at all, so you can only get a signal within a certain error distance of a point.

For brands other than KUKA, they'll each have their own special equivalent unique to themselves.

The slower the robot is moving, the more accurately you can do this.  Alternatively, if you can afford to physically stop the robot at each position (and provide some settling time to handle vibration), getting the coordinates at the stopped position isn't hard.  But from the way you wrote your question, I suspect you're looking for on-the-fly coordinates.
