Filling a box and then moving it with a PM mobile robot


I’m a new user, learning for a school assignment. I’m trying to simulate a process in which some really small pieces fall into a box filling it (about 1000 pieces per box). And then I would like to move that box into a new conveyor where another process would take place. Any ideas how? I kinda came up with a physics conveyor that outputs the small physics pieces on top of another physics conveyor that outputs the physics box but then I cannot get the mobile robot to move the box from the physics conveyor to another physics conveyor. I’m not even sure that this is the correct approach so any hint (or solution) would be much appreciated :slight_smile:
