Handing over MU between two grippers

Andreas 2 months ago in realvirtual.io Starter and Professional updated 1 month ago 3

Hi,

how to solve the following problem in handing over situations:

- gripper 1 grips MU. MU is now attached to gripper 1

- some transfering is done

- gripper 2 grips MU. MU is gripped by gripper 1 and gripper 2. MU is now attached to gripper 2


If gripper 2 opens now, the MU is no longer attached to gripper 2 and falls down. 

What I want to achieve is:

Gripper 1 is still closed and the MU should now be attached to gripper 1 again. 


How can I solve this? 

I realized that the Property of MU (Script) "Parent Before Fix" doesn't get updated between handover of two Grip (Scripts).

Gripper 2: RT_Pos2_Gripper

Thank you for any advices.

It seems the issue is that the part is being gripped by two components, which is something we currently don't support. Typically, we use a combination of a Fixer (for the passive part) and a Gripper (for the active part). In the coming days, I'll be creating a test model to explore whether we can extend the functionality of the Gripper to address this.

Exactly.

I thought I can do a workaround by using the property "Parent Before Fix" but it's not updated in the MU script when MU get gripped by two grip scripts.

Looking forward for your solution. ;-)
