I want the robots to build the far solar array. They are travelling the red route.
At the green circle they run out of battery and return to the closest roboport (there starting roboport)
Why are they not travelling the cyan route?
They are doing this for at least an hour.

Robots are dumb and fly only on straight line, so you have to take that into an account when building logistic network.

Advantage of robots being dumb is that they are not computationally intensive.
