Weeks+Shipping: Out of stock. Amazon US lists it as currently unavailable, and Letianpai's online store no longer carries it (October 2026 check). Only used units turn up.
Remote control: Only through Android tooling. Connect over USB and use adb, or flash the maker's full-root firmware (Windows-only tool) to switch to the Debian side and run Python on the robot, which community notes say cannot join Wi-Fi in that mode.
Overview
Rux takes the EMO idea of a walking desk pet and scales it up, with a round touchscreen face, a 5 MP camera and a full Android system inside. Its four micro servos give it a stubby two-legged walk, and like Vector it watches for desk edges and walks itself back onto its wireless charging pad. The catch is support, since early owners reported a weak personality, flaky Wi-Fi and poor customer service, and by October 2026 the maker's store and Rux site no longer offered it.
An ambitious walking ChatGPT robot that is now hard to buy and has thin support.
