Autonomy in Action

4M uses autonomous systems – some developed in-house, like the Golem Detector – to make land clearance faster, safer, and more precise.
Our tools scan terrain in real time without exposing personnel to risk, reducing manual workload and accelerating operations.

Golem Detector

Golem Detector, developed by 4M Defense, is the world’s first fully autonomous robot for detecting UXO and buried metal threats—safely, accurately, and without exposing personnel to risk.

Powered by the trusted UPEX®️ 740 MF-3 sensor and equipped with built-in GNSS mapping, Golem delivers deep detection, intelligent filtering, and real-time underground threat mapping.

Compact and rugged, Golem eliminates manual scanning and false positives, reducing workload and accelerating results.
Designed by 4M’s field-driven innovation team, it’s ideal for UXO clearance, infrastructure inspections, and post-conflict surveys.

Field deployment begins January 2026.
Golem redefines detection—with unmatched safety, speed, and precision.

Sensor Drone

The MagArrow II is the second generation of our best-selling UAS-enabled magnetometer and it’s setting a new standard for UAS magnetic surveys. The MagArrow is engineered to simplify surveys that are difficult due to the various limitations of pilot-on-board surveys and ground surveys. The MagArrow is a robust yet flexible system that can adapt to changing field conditions and new user workflows. The MagArrow consists of an aerodynamic, light-weight shell with internal electronics including the MFAM™ magnetic sensors, GPS, and IMU. The MFAM™, a two sensor module inside the MagArrow is our most groundbreaking magnetometer yet, capable of highly precise measurements in an extremely lightweight and tiny package.

Digger Scraper

4M Defense owns the “Digger Scraper,” a digger that is remotely controlled without the need for an operator to be inside it during operation, thanks to the advanced SCRAPPER technology.

Digger D-250

The Digger D-250 is a remote-controlled demining platform designed for safe and efficient use in high-risk areas. Built with 250 HP, rugged armor, and tool flexibility, it operates reliably in extreme conditions. With GPS-RTK and optional cameras, it ensures precise, long-distance control and maximum operator safety.
