32 robots on the line. If each is always doing its job on a unit(because it's a pipeline), and a unit gets all 32 pieces done in 30 seconds, then each robot is spending about a second on its unit. That means a completed unit every second.
I've programmed ABB, Epson, Denso, and Fanuc 6 axis robots (no Mitsubishis, but I've seen a few) and there's no way that those robots are running at 1-second cycle times. Maybe with a delta or SCARA, but just moving 200mm and back with the inertia of the robot alone will take you on the order of a second.
It's almost certainly 30 seconds part-to-part, taking 16 minutes (minus 30 seconds for each of the stations that have two or more robots) from the start to the end of the line. It's not particularly important how long it takes from the start to the end of the line, and they'd be unlikely to share that trivia with a journalist - but part-to-part cycle time is important.
If the TAKT time demanded a completed unit every second, they'd run multiple lines.
