Parviz · field manual

Every part, wire, and decision behind Parviz.

A Raspberry Pi 5 head, 7-inch animated face, camera eye, pan/tilt neck, and twin deployable antennas, riding a two-track tank chassis with always-on sensing and a local LLM brain. These pages are the build’s source of truth, rendered from the repo by make docs.
