# OpenCat — Open-Source Quadruped Robot Framework OpenCat is an open-source Arduino and Raspberry Pi-based framework for building and programming quadruped robots. Developed by [Petoi](https://www.petoi.com?utm_source=github&utm_medium=code&utm_campaign=github-opencat), the maker of futuristic programmable robotic pets, it powers both the Bittle robot dog and Nybble robot cat platforms. The framework handles the hard parts — gait coordination, servo control, IMU integration — so you can focus on what you're actually building on top of it.   --- ## About the Project Inspired by Boston Dynamics' Spot, Dr. Rongzhong Li started OpenCat in his dorm at Wake Forest University in 2016. The goal was straightforward: make agile quadruped robots affordable and hackable enough for researchers, educators, and makers — not just well-funded labs. OpenCat is now deployed across two robot platforms and used in K-12 schools, university research labs, maker spaces, and independent projects worldwide. ### Current Hardware - 🐶 [Bittle X — robot dog with voice control](https://www.petoi.com/products/petoi-robot-dog-bittle-x-voice-controlled?utm_source=github&utm_medium=code&utm_campaign=github-opencat) — current generation, BiBoard/ESP32 - 🐱 [Nybble Q — robot cat](https://www.petoi.com/products/petoi-nybble-q-robot-cat?utm_source=github&utm_medium=code&utm_campaign=github-opencat) — current generation The original [Bittle](https://www.petoi.com/collections/robots/products/petoi-bittle-robot-dog?utm_source=github&utm_medium=code&utm_campaign=github-opencat) and [Nybble](https://www.petoi.com/collections/robots/products/petoi-nybble-robot-cat?utm_source=github&utm_medium=code&utm_campaign=github-opencat) (NyBoard/ATmega328P) are discontinued but still fully supported by this codebase. This repo is the right place for NyBoard users; for ESP32/BiBoard see [OpenCatESP32](https://github.com/PetoiCamp/OpenCatESP32).  --- ## What the Framework Gives You - **Multi-language:** C/C++, Python, block-based coding - **Open hardware + software:** fork, modify, extend — no vendor lock-in - **Arduino + Raspberry Pi native:** works with the tools you already use - **Sensor integration:** cameras, touch, IMUs, ultrasonic, etc. — clip and go - **Sim-to-real:** experiment reinforcement learning models on an affordable robot - **ROS compatible:** SLAM, navigation, and perception pipelines documented by the community Whether you're teaching **robotics programming** for the first time or running a graduate-level AI experiment, the platform scales. --- ## What the Community Has Built Users have shipped real **robotics projects** across AI, Raspberry Pi, and research — a few highlights: - [Autonomous movement & object detection](https://www.petoi.com/blogs/blog/reid-graves-robotics-ai-applications-with-bittle-robot-dog-raspberry-pi?utm_source=github&utm_medium=code&utm_campaign=github-opencat) - [Raspberry Pi robotics projects](https://www.petoi.com/blogs/blog/tagged/raspberry-pi?utm_source=github&utm_medium=code&utm_campaign=github-opencat) - [AI and computer vision applications](https://www.petoi.com/blogs/blog/tagged/showcase+ai?utm_source=github&utm_medium=code&utm_campaign=github-opencat) - [NVIDIA Isaac simulations and reinforcement learning](https://www.youtube.com/playlist?list=PLHMFXft_rV6MWNGyofDzRhpatxZuUZMdg) - [Visual and LiDAR-based SLAM with ROS](https://www.youtube.com/watch?v=uXpQUIF_Jyk&list=PLHMFXft_rV6MWNGyofDzRhpatxZuUZMdg&index=6) - [Imitation learning with Tiny ML models](https://www.learnwitharobot.com/p/imitation-learning-with-petoi-bittle) - [IoT robot fleet management with AWS](https://www.petoi.com/blogs/blog/aws-iot-robot-fleet-demo-with-petoi-bittle?utm_source=github&utm_medium=code&utm_c
