Three additional roboports to fill gaps in the list of available ones. Ideal for bot based megabases. All roboports offer a small logistic supply area so they can be fitted into small networks which should be kept separated from the rest, and all offer enough loading pads and energy to reload even big hoards of robots (Standard: 4 charge pads, 1MW each; the ones here: 32 charge pads and 50 MW each), as long as you can provide enough energy.
The extender port offers a huge construction area for extending/expanding the base, while the two production site focused roboports don't do this. The production roboports come with two different sizes of logistic areas (32x32 and 64x54). Pick what fits best.
