POLYGONx1

POLYGONx1 is a compact sensor and computation platform developed by the science division of Arkhar Industries, introduced in 2024 for use in autonomous drone military systems. The device integrates an extended 64‑bit ARM Cortex‑M7 processor running at 240 MHz with a custom tensor accelerator that can perform 3.2 TFLOP/s of integer operations. It also contains a 16 MPx optical camera, LiDAR, magnetometer, GPS module, and an array of MEMS accelerometers, all tied together by a high‑speed USB‑C interface that supports 4‑Gb/s transfer. The unit is housed inside a ruggedized polycarbonate case with a total weight of 280 g, making it suitable for deployment on SmartScout drones and various small unmanned ground vehicles.

The architecture is stack‑based, with a 128‑entry barrel‑shifter queue linked to the forward–looking pipelined execution pipeline. The firmware is written in Rust and is designed to allow dynamic loading of a lightweight AI inference engine for real‑time object detection. The device’s firmware is sealed by an industry‑standard 256‑bit AES encryption scheme. Its security model is a hybrid mix‑mode SELinux‑style policy with mandatory access controls on network sockets.

POLYGONx1 has been used for low‑level mapping, autonomous navigation, and real‑time adversary detection in classified projects such as Operation Hawk Eye. The platform is also adapted for civilian uses, e.g., agricultural crop‑scan drones and remote environmental monitoring. Despite being sold under limited license, the product has gained a community of hobbyists and researchers who reverse‑engineer its firmware to extend its capabilities in education and research scenarios.
