That cell is a line tracking cell. Doing it with external axis, or digital interface is the wrong way to do it.
You will have to add a fixture, then under that, add a line (shown as conveyor in my picture below), then add a link, which will act as an encoder to the robot controller, which you map in the link properties.
Then in the controller, you define what type of tracking is being done. In the case of your video, circular on one of them, and line on the other.
You then use the conveyor toolbar to jog it.
Hi Nation, there is no option to add link to my fixtures as in your picture:
Can you please add more details about the process, I am really struggling to figure out how exactly these things are done in roboguide, pretend that you are explaining it to someone who does it (motion) for the first time in Roboguide.
