The name

In Homer's Odyssey, Argos (also spelled Argus) is the faithful, swift-footed hunting dog bred and raised by Odysseus. When Odysseus comes home after twenty years, disguised as a beggar, Argos is the first to recognise him, lying old and neglected by the gate.

We named the robot after him for the same qualities we want in a field machine: loyal to the people who rely on it, quick over rough ground, and built to work. The mark is his head, drawn in straight lines; the bronze nose, repeated in the word "Argos", is the only colour in it, and the same inverted triangle sits on the robot's grille.

Who owns it

OpenArgos is owned and developed by Caldorion, Inc. Caldorion designs the robot, maintains the project and holds its intellectual property: the design, the 3D models, the documents and the renders are © 2026 Caldorion, Inc. The OpenArgos name and mark are trademarks of Caldorion, Inc.

Why we open it

An outdoor robot is only as good as the problems it is tested against, and no single team sees enough of them. By opening the design we want to:

• Let people check the work. Anyone can see how the robot is built and why, and point out what could be better.
• Let partners build on a common platform instead of starting from scratch: payloads, sensors and software can target one documented interface.
• Earn trust. A machine that works outdoors around people should be open to inspection.
• Grow a community of builders, researchers and operators who improve it faster together than any of us could alone.

Opening the design does not change who owns it. Caldorion keeps the OpenArgos name and mark, so that anyone can tell the original project from a fork. The license that will set out what others may do with the design is still being chosen; until it is published, all rights are reserved.
