Bittle X is a palm-sized, open-source quadruped robot dog kit from Petoi with nine servo-driven joints, an ESP32-based BiBoard controller, and built-in voice control with 35+ voice commands plus up to 10 programmable custom commands. Aimed at STEM education and hobbyists, it is programmable via block coding, Python, or C++ on the OpenCat open-source framework and is sold as a construction kit or pre-assembled, with an optional robotic arm gripper on the V2 model.
Sold directly on petoi.com in seven variants ($299-$469 USD). Verified today via the official store's Shopify product JSON: the six Bittle X V2 variants ($319-$469) are available:true and purchasable; the original 'Bittle X - pre-assembled - lite servos' variant ($299) currently shows available:false (sold out). The petoi.com /collections/robots page lists Bittle X as in stock 'From $299.00 USD' with a Buy button; the product page's static pre-JS render shows a default 'Sold out' label that does not reflect per-variant availability.
