Pupper v3
An open-source, 3 kg robot dog with brushless motors, a fisheye camera, a screen face and a microphone, designed to teach motor control and reinforcement learning. Stanford's CS 123 students build one from a starter kit each spring. It is a teaching and research platform you assemble yourself, not a finished pet.

- Price
- $2,000Shipped The project says you can build Pupper v3 yourself for about $2,000. Reseller AIFITLAB sells a parts kit from $1,450 that excludes printed parts, battery and controller.

A dash means the maker has not published it. Values with a label are claims, not measurements.
Trust and legalWhat these mean
Does a remote human drive it?
Partly
Walks under gamepad control; students add learned locomotion, object tracking and voice responses.
US FCC
Not applicable
A self-built open-source design with no whole-robot FCC authorization; radios are in the Raspberry Pi. At 3 kg it exceeds the 2 kg mobile-robot threshold, but the July 2026 rule does not address hobbyist kits and it is designed in the US.
