@Debbie No, nothing disappeared in the video. About half of the video involves troubleshooting and fixing potential issues for a reason. For example, the robot might be positioned wrong, the vehicle might not have capacity, the route is not configured properly, feed and needs mismatched, etc.
You are doing a good job of using the forum to ask questions. And I appreciate your resolve to work through these issues.
The course, its lessons, layouts and components were made with 5.2 version of Works library. The layout used in the lesson can be downloaded from the academy, and used to complete the lesson. Note that all of the course files can be downloaded and are mentioned in this forum post.
I have not opened your layout, but if you took the components from the eCatalog, they are most likely 5.3 or higher version of Works library. There are differences between 5.2 and 5.3.
What does that mean? In the lesson’s table of contents, click 11. Create pattern and simultaneous feed. Notice that the Simultaneous check box of the Feed task is enabled. Now, starting from 11:30 in the video you can see the robot is able to pick up more than one part using the route in your original post.
As @jouha mentioned, you need to specify the number of picks the robot does at a station in the route. And that is what you need to do with 5.3 or higher version of Works library when defining a route for the vehicle. In 5.2 version there was a bug that allowed you to workaround this, but it probably caused more problems than it solved, so the bug was fixed.
