how to transfer the data from vision sys to robot

[indhu]

I'm doing a project on robotics interfaced with vision system.
Objective is that the robot has to pick up the component anywhere within the field of view(we use only one camera) without teaching it. using vision builder AI the center of the object is determined.
Now our problem is how to calibrate the coordinates of the robot with that of the coordinates of field of view so that the robot moves to the exact location?
We have a Fanuc LR R-J3iB Mate 5 axis controller robot whose base is fixed and a camera assembly next to it.
Please give your valuable informations which will be very much useful in our project.
Thankyou,
Indhu

Induh,

use the calibration step to do two things:
- let the vision system know how many pixel are one or x roboter steps
- set the coordinate system of the vision system to get the same like the roboter has.
