How do huskybots get fixed?
Gateway has multiple repair bays, in each major sector. The bays are sized for each class of platform. They are supplied using automated mining drones that harvest materiel from asteroids and other lifeless orbital bodies in the star systems surrounding Gateway. Some bays are unmanned, using assembly arms and automated fabrication, 3D-sintering/resin laser printing, and mechanical machining for manufacturing standardized parts. Other bays are staffed by functioning platforms, but those are also used for Gateway's ships, shuttles and equipment repairs. Those bays are also offered to Gateway's visitors, and are available for commission on a negotiated fee structure.
The bays give up after confirming the timestamp of the latest backup from the platform has synced through Packnet. New platforms can be built. The data is the important part.
