PocketBots will give you access to a new armor module, PocketBots. This module acts just like a portable roboport.
This version works with multiplayer.
The roboport will only activate when you are outside other roboport range and there are things for your robots to do, like repair a building or build a wall. Also make sure you have enough power in your armor to run the thing. It will use 700w when in use. (This is not true. there is a bug. they only use power when you are running around.)
