Compared to domestic package sorting and the army of personnel required, this looks good.
However, a huge portion of the robots are unladen. They might be transiting entire width of production line yet aren't moving as if destined for next package.
It doesn't show the construction; levels below to receive output of the chutes. Pretty sure the trucks aren't parked in that tight.
And the red one is lost........
