How to load and move multiple items on a 'mobile robot' (Auto Assembly...?)

General Questions

Hello VC users, I’m using VC version 4.9.
I have something to ask you to help me with.

As the title says, I would like to load 3 items into the current ‘mobile robot’.
But if you look at the attached file (P02_Forum_02),
After one item is loaded into the ‘Mobile Robot’, go to the next process immediately.

Does anyone know how to set it up to move after 3 items are loaded on the “mobile robot”?

I heard that it’s using the “Auto Assembly” function,
Even if I watch that video, I don’t know how to apply it to my situation.

I need your help.
