Petoi Bittle
Palm-sized open-source quadruped robot dog
$230.99 – $289
Petoi Bittle is a compact, palm-sized open-source quadruped robot dog designed for coding, STEM education, and hobbyist robotics. It ships as a construction kit that users assemble, then control via remote, a mobile app, or by programming it in block-based code, Python, or C++. Built around an Arduino-compatible controller, it performs lifelike animal-style movements and tricks.

Overview
Petoi Bittle is a palm-sized, open-source quadruped robot dog built for hobbyists, students, and educators interested in robotics, coding, and AI. Rather than rolling on wheels, it walks and runs on four legs and can play animal-like tricks, giving it a lifelike, bionic character. It originated from founder Rongzhong Li's OpenCat project and was crowdfunded on Kickstarter before becoming a standard Petoi product.
The robot is sold as a construction kit that buyers assemble themselves, which doubles as a hands-on introduction to mechanical and electronic systems. It is built around an Arduino-compatible microcontroller and includes an inertial measurement sensor, programmable LED lighting, and digital servo joints that drive its gait and posture.
Bittle can be operated with an infrared remote or the Petoi mobile app, and its open-source firmware lets makers program new behaviors using block-based coding, Python, or C++. This openness makes it a popular platform for STEM learning, experimentation, and robotics research.
