About Petoi

Petoi creates affordable, interactive, and lifelike robot pets designed to make robotics education and AI learning accessible to the mass market. Founded by Rongzhong Li, the company emerged from the OpenCat project in 2016 and successfully crowdfunded its first products on Indiegogo and Kickstarter in 2020. The brand offers three main models: Bittle (robot dog), Bittle X (robot dog variant), and Nybble (robot cat)—all featuring programmable, open-source platforms compatible with Arduino, ESP32, and Raspberry Pi.

These compact, lightweight quadruped robots deliver lifelike movement with authentic mammal gaits, setting them apart from typical toy robots. Each model supports multiple coding languages including C++, Python, and block-based coding, making them suitable for various skill levels. The robots feature innovative elastic joints for durability and are highly extensible with sensors and modules. Available as pre-assembled units or DIY kits, they include remote/app control, Bluetooth and WiFi connectivity, and approximately one hour of battery life per charge. Petoi’s mission centers on providing hands-on STEM education while offering companionship through interactive robot pets, with a vision to become a worldwide leader in personal companion robots.
