Isolator or Isoshields are a kind of forcefield bubble that is selectively permeable to the atmosphere, temperature and nanosphere where present. Large, static devices can create isolation zones encompassing entire buildings. Smaller, mobile machines have a correspondingly smaller field size.
Iso-drones are general purpose drones fitted with mobile isoshield generators. Those in service with the Concord C3 are based on C3D1 General Purpose drones, whilst other variations are found based on all manner of similarly sized drones. They are commonly used on worlds with intolerable atmospheres to provide safe refuge for survey and exploration teams.
Iso-drones are heavily protected by kinetic armour as well as substantial nanocored casing. The isoshield creates immense gravitational resistance that makes it impossible for the drone to move very quickly. As a result, the iso-drone is a sluggish machine that moves only slowly.
