This mod is great, but it would be even better if the various Spidertrons could use roboports as well - both the "personal roboport" they can normally use and the "vehicle roboport" added by K2.

I went digging in K2's equipment files, and this is what they set for Spidertron, which I've copied over to line eight of your data_updates.lua:

    it.equipment_categories = {
      "universal-equipment",
      "robot-interaction-equipment",
      "vehicle-robot-interaction-equipment",
      "vehicle-equipment",
      "vehicle-motor",
    }

Great! Many thanks for the suggestion and solution! I'll just copy these definition into the mod and update it :)

I'll just keep the armor category here because this was there from the mod by default so making this an addition to the equipment categories instead of a replacement.

Mod updated, have fun :)!
