Tritium OS is the operating system that runs on your robot's onboard computer. It handles everything that happens locally on the robot — motor control, sensor processing, audio, networking, and running the services that power the Tritium UI.
Tritium OS is built from independent programs called "nodes" that communicate in real time. This modular design means each part of the system (motor control, speech, audio, etc.) runs independently.
You can see the list of running nodes and their status on the System page.
For a technical overview of all nodes, see the developer nodes page.
