Autonomous Systems
for Extreme Environments

WE DO NOT FAIL THE MISSION

We design autonomous systems for the places where failure means loss - deep ocean, hazardous atmospheres, contested environments. Every product speaks, senses, logs, and survives.

Current Research and Products

Prototyped, tested, and moving to production. Real hardware, not renders.

ATLAS handheld field instrument prototype
Flagship Platform
ATLAS
Handheld multi-sensor field instrument

Offline-first environmental and hazard awareness with real sensor fusion — not vibes. Designed to log, explain, and survive in places that don’t forgive mistakes.

Ocean Science
TRITON Buoy
Autonomous, affordable ocean node

A working buoy built for real deployments: senses, logs, and broadcasts openly over LoRa so ocean science can scale from “one unit” to “a network.”

LoRa broadcast Autonomous Network-friendly

Fire Response Research
PHOENIX
Large 12-motor hexacopter

Large 12-motor hexacopter designed to detect forest fires and deploy fire suppression grenades that disperse roughly 15–20 feet above the fire.

That is not marketing. That is how every product on this page started. A sketch, a conversation, a problem that needed solving. We do not wait for permission, funding committees, or five rounds of review. We design the board, print the prototype, write the firmware, weld the hull, and put it in the water. If it works, we refine it. If it breaks, we learn why and rebuild it by morning.
We are old school - and that is a very good thing. We build real prototypes. Not renders. Not slide decks. Not simulations that look good on a projector. Real boards with real components soldered to them. Real enclosures you can hold. Real vehicles that go in real water. When you work with us, you get hardware on a bench, not a PDF that says hardware is coming. That is how engineering was done before the industry forgot, and it is how we still do it. It wins every time.
Nineteen years across missile systems, flight simulators, medical devices, and autonomous robots taught one lesson: the distance between idea and real hardware should be as short as possible. Bring us the napkin.

The Lab

Second Robotics Laboratory - Sophie prototype at engineering bench
Sophie prototype at the engineering bench — Webster Groves, Missouri

Second Robotics LLC is a research and development laboratory in Webster Groves, Missouri, specializing in autonomous systems for extreme environments. We design hardware that works where software alone cannot be trusted - underwater, in hazardous atmospheres, in radiation fields, and at the edge of the continental shelf.

Our core technology is the ATLAS Command Module: a dual-processor board with independent speech synthesis, real-time power monitoring, and sensor expansion that serves as the brain of every product we build. One board, one architecture, ten products. No modifications.

Every system we design follows the same philosophy: the smart processor is allowed to be ambitious. The reliable processor is required to be dependable. They are not the same processor. And the reliable one does not need the smart one to bring the vehicle home.
