I found this video totally mesmerizing. The level of robotic automation is incredible, and the agility with which the robots handle the materials is impressive.
I always ask myself in such videos, when there's one step that is 1:04 & 2:08 done by human hand, what was it about this step that a robot was unable to reliably do? (I think it's a light metal bead that can easily end up at the wedding angle in three first one, and inspection for defects at the latter one.)
Why would they stockpile hundreds of spools of rubber at 0:53 rather than using them right away - is rubber harvest seasonal which could fall short of production demands? (Yes!)
(How latex is harvested. - Tapping cannot occur when the bark is wet, so heavy rain reduces the number of workdays for farmers...Tapping is almost always done at night or in the early morning. This is because cooler temperatures lead to higher internal pressure in the tree's vessels, allowing the latex to flow for a longer duration before it naturally coagulates and seals the cut. Rubber trees contain latex in "laticifer" vessels that run vertically but slightly spiraled. By cutting at a 30-degree angle, tappers intersect the maximum number of these vessels to get the most liquid out. The cut needs to be deep enough to reach the vessels but shallow enough to avoid the cambium (the tree's growth layer). A precise, angled shave allows the bark to grow back smoothly. )
