ATOS and Companion: What's the difference?


Formerly known as SXD System Firmware, or simply System, this is the main civilian operating system used by Nanite Systems robots. It includes a wealth of features oriented toward everyday use to help robots fit better into society, such as the personas system, speech filtering, and an integrated RLV relay. By itself, it does not include any combat features such as heat simulation, damage, or the recognition and reloading of weapons. A unit running just Companion only has to worry about keeping its battery from running out and dealing with EM interference, which can be mitigated with an interference shield such as our MESH-2100.

Supported controllers: all

Companion currently comes pre-installed on all systems. Re-installation and updating instructions are here.


ATOS stands for Advanced Tactical Operating System. It is a name shared by several related products:


ATOS Elements is an add-on for Companion that adds combat features. When ATOS Elements is installed, a Companion-powered robot can download information from the local weather station to determine the ambient temperature (based on the time of day and altitude), will automatically manage fan speed or liquid cooling to keep itself from overheating, can recognize weapons (including monitoring ammo levels, temperature, and reloading the weapon), can be damaged, can automatically erect a shield to block projectiles if a compatible generator is installed and configured, and can be repaired by tools and repair stations. Additionally, such units can automatically self-repair up to 90% of all damage taken, using integrated nanite emitters.

Supported controllers: all, provided Companion is already installed

Getting ATOS/E:  see updating to the latest firmware


ATOS Cortex is the complete version of ATOS designed for use by our current generation of controllers and robots. It replaces Companion entirely, offering the combat features found in ATOS/E (temperature, weapons, damage, projectile shielding, repair) but removes civilian features that are not necessary for combat operations such as personas, speech filtering, guest access, RLV relay support, and some levels of permissions restriction. Units running ATOS/CX are more autonomous, and better suited to fast-paced, low-latency combat. The ATOS/CX heads-up display, SHIELD, is also distinct, creating an experience much more familiar to anyone with first-person shooter experience.

Supported controllers: NS-112 Aide, NS-115 Scout, NS-476 Aegis
Release date: Coming soon (est. late 2020)


ATOS for Devices is a stripped-down version of ATOS/CX intended for use with autonomous, non-agent robots such as UAVs. It is intended to provide for combat, patrol, and reconnaissance capability.

Supported controllers: NS-700 series autonomous drones
Release date: Coming soon (est. early 2021)


ATOS Health is a combat implant for humans and other organics. It provides connectivity with standard ATOS features like integrity (hit points), temperature, weather, and air pressure, and identifies when the user is suffering from conditions like hypothermia, heat stroke, or hypoxia.

Supported controllers: Not intended for use with a controller
Price: L$300. Now available. See Marketplace listing here to purchase.


ATOS Arena is a server for combat that will add more depth to ATOS-based engagements, including scoreboards, team-based respawning, and game modes for point control and capture the flag.

Release date: Coming soon (est. mid 2021)
