About

About Mithra OS

Mithra OS is ARX Robotics’ AI-enabled operating system for adding autonomy, connectivity and standardized software to legacy and modern military vehicles. It combines sensor fusion, situational awareness, over-the-air updates, a legacy autonomy framework and an interconnectivity/swarming pilot for manned-unmanned and unmanned-unmanned teaming.

ARX offers Mithra OS for order, custom integration and tender support. The associated autonomy kit is one application of the operating system, not the whole product. ARX states that its systems are deployed with several European armed forces and used in Ukraine, but public evidence does not establish that every deployed ARX vehicle uses every Mithra module. Company financing is therefore not treated as an exact-product event.
