Tesla posted a new video about their secret Kato Road 4680 cell production lines a couple of days ago, and it contains a couple of technological gems I haven't seen widely mentioned elsewhere yet, so here's an attempt at listing these new disclosures.

The first thing is that there appear to be no human workers/operators whatsoever in the main production process.

To the left is an image of line workers handling finished cells in a traditional facility. To the right is the 100% automated conveyance system Tesla has.

Here's how their 4680 cells are transported in racks of 8x8 cells: 64 cells each.

These standardized racks likely interface into automated pack production machines, made by Tesla Grohmann, or get directly integrated into the die-cast underbody (structural battery pack).

There's an interesting detail in one of the frames: glimpse of a facility worker observing an industrial robot moving a rack.

What is interesting is that:

✅ Cell production facilities are Class 7 clean rooms, while the worker doesn't wear the usual "bunny suit" protective gear.
✅ There's a barrier between the worker and the robot: likely separating clean-room air from unprotected air.
