I understand that the last movement command won't execute unless 1 and 2 are complete in the example we discussed. This is a good point. To solve this problem you should run each group of robot movements for the same robot on a separate thread. A separate script would also work (it ends up being a separate thread).

The example MoveRobot script of the "Synchronize 3 Robots with a Screen" example does exactly that (it moves each robot on a separate thread).
