robotindex Letianpai Rux Robot
A screen-faced desktop AI companion from Letianpai (乐天派), a funded Beijing hardware startup — a round emoji-style face display, a 5MP monitoring camera, and genuinely functional bipedal legs driven by six servos, running a full Android-based OS with ChatGPT integration and an open developer SDK. It's sold under several different storefront names across marketplaces, including "QUJUSO" on some Amazon listings — same product, not a separate brand.

Reference Price
Pricing is inconsistent across channels: a Xiaomi Crowdfunding campaign listed a full price of $469 (marked down from $599) before selling out, and a third-party robotics aggregator estimates an ongoing retail range of $299–469. This catalog could not pull a live, confirmed price directly from Amazon at research time, so treat any specific price as approximate until checked against the live listing.
Insights
This catalog's original name for this entry conflated a generic reseller storefront, "QUJUSO," with the actual manufacturer; the robot's real maker is Beijing-based Letianpai, which sells the identical robot under its own name, with "Rux" as the robot's consistently-used real product name across every official channel. Letianpai's GitHub organization also publishes genuine GPL-2.0-licensed core firmware for the robot, confirmed against the repo's license file, earning this entry its Open Source badge.
Firmware & Community
Letianpai-Robot/GeeUI_ROM
Letianpai's own official, GPLv2-licensed open-source system ROM for GeeUI, the software platform running on the Rux Robot.
Verified against Letianpai's own store and product microsite, its GitHub firmware organization (including direct inspection of its core repos' GPL-2.0 license files) and Facebook page, its Xiaomi Crowdfunding and Indiegogo campaign pages, a USPTO trademark record for QUJUSO, EqualOcean's funding coverage, a 36Kr/PitchHub investor profile, and independent reviews from Impulse Gamer, mia-cat.com, OriginOfBots, RoboticHunt, and a personal blog (Docandersen). Flagged as inconsistent or unconfirmed: screen size (2.1" vs. 2.4" across sources), battery life (30 minutes to 5 hours depending on source), current retail price (not independently confirmed from a live Amazon listing), the company's headquarters city (Beijing per its own site vs. Shenzhen per one press source), and a promotional claim that Letianpai's CEO is "the ninth founder of Xiaomi," which could not be verified. This entry corrects its prior name, which combined a reseller storefront name (QUJUSO) with the manufacturer's name as if they were a joint brand.
