Rex

Wheeled security robots stop at the first flight of stairs. Rex doesn't — its four legs handle steps, cable runs, and uneven loading-dock floors that would strand anything on wheels, which is the entire reason facilities teams ask for it by name.

Sees what a guard would miss

A dual thermal-and-optical camera head lets Rex flag a hot electrical panel or a leaking pipe on the same patrol pass where it's also checking for open doors — inspection work that used to mean two separate walkthroughs.

Built to run without supervision

Rex plans and re-plans its own patrol routes, working around blocked corridors or parked equipment without a human re-drawing the path. Five hours of runtime covers a full overnight shift on most facility footprints; when it's low, Rex returns to its dock on its own.
