Confused about Vision Master Recovery vs. All Axis Mastering

  • Recovery is supposed to recover back to a previous mastered state.


    Vision mastering is not actually all axis. It uses vision and a grid to master J2-J5. You still need to single axis master J1 & J6.

  • Recovery is supposed to recover back to a previous mastered state.

    Could you elaborate on the on the recovery part: what previous mastered state?

  • For recovery, you start with a robot that already had good mastering. Then I believe you have setup a vision recovery program.


    Then if you ever lose mastering you can run the recovery program to get it back to the exact same mastering.



    Never used it myself but I have used the normal vision mastering. It doesn't require any setup and it generates new mastering values. Not necessarily exactly the same as any previous mastering.

  • Ok, thanks.

    As far as the normal vision mastering goes, would it help me in the following scenario:

    I have a robot that runs well after I performed a vision mastering with a robot mounted camera.


    I have to swap the robot for whatever reason. I mount the eoat on rh new robot, the calibration grid is still in the same place.

    I remater the new robot.

    Will the points be the same, or do I still have to do do touch ups?



    I work in manufacturing directly, we have TONS of different recipes and swapping a robot always requires a lot of touch ups...

  • Its only going to work if you have previously taught a very accurate user and tool frame on the first robot, that it uses for all important points. Then you must be able to re-teach the user and tool frames the exact same way on the new robot.


    Even after doing that your positions could still be off by up to a mm due to mechanical differences.


    If you really want it perfect then everything must be perfect. Flat level mounting surfaces, dowel pins to locate the robot base and end effector, accurate user and tool frames done with a good sharp pointer or through vision, and the best mastering is iRcalibration Signature, vision mastering is 2nd best.


    All depends how good is good enough and how much money/effort you put into the original setup.
