Roboport
The Roboport is the home for all Robots. It also spawns an area of 50x50 tiles, in which the robots can fly.
Two or more roboports can build a Robotic network, if the borders of the covered areas connect.

Unuseable knowledge
You can insert robots and repair-packs into the port with an inserter, but since there is currently no control about the inserted number, this is unuseable knowledge.
