The specifications.
Hardware, build and software on one sheet. Every fact links to where we found it.
Orion is a custom-built 12-DOF quadruped with a 3D-printed chassis and 2-part silicone injection-molded feet. It uses a Jetson Orin Nano for high-level AI and perception and a custom STM32 PCB for low-level control; its software includes ROS2 SLAM and navigation.

Can you sell it?
Check firstCheck before commercial use
No license was found for the design files, so no reuse rights are granted. Ask the maker before building anything to sell.
