predicted collision

We have a Multimove system with 3 IRB1200 robots.
There are multiple defined zones inside the robotcel to predict collision.
Now we want for a new product that one robot pick a product from another robot.
Because the grippers are also defined as a zone, we get an predicted collision error.
It is possible to switch off the predicted collision detection with a Rapid command?
Or is there a better solution?

    Hello there,

    A couple of points:

    1) There is a system input signal "Collision avoidance" which can be manipulated via Rapid to disable/enable CA.

    2) In RW6.11 there's a Rapid instruction "IsCollFree" which might be of use to you if you use RW6.11.

    3) R&D has received multiple requests recently for dynamically removing parts of the station from Collision Avoidance and ways to handle predicted collisions without a system halt.

    4) You could contact your local ABB contact and ask them to add you as a supporter of these feature implementations. The case is called "PDD11239 - Collision Avoidance improvements" in our systems (they will know what to do with this information).

    Hope this information is helpful.

    thanks, that is very helpful information. I'll try to implement it.
