OpenCat: An Open-Source Robotic Pet Framework
OpenCat is an innovative open-source project developed by Petoi, designed to inspire and facilitate quadruped robotic research. Utilizing Arduino and Raspberry Pi, it serves as a robust framework for creating agile and programmable robotic pets.
Origin and Inspiration
OpenCat was initiated in 2016 by Dr. Rongzhong Li at Wake Forest University, drawing inspiration from Boston Dynamics' Big Dog and Spot Mini. A year later, Petoi LLC was founded to advance the development of these robotic pets, making them more accessible and affordable for educational and engineering purposes.
Project Goals
The primary aim of OpenCat is to encourage collaboration in the study of four-legged robots. By producing affordable robot pets, it seeks to introduce STEM concepts to a wider audience, inviting both children and adults to engage in the robotics and AI fields.
Kits and Features
OpenCat is implemented in Petoi's Nybble (a robot cat) and Bittle (a robot dog), both palm-sized with realistic movements. These robotic kits are not only affordable but also mass-produced and shipped globally, making them accessible to anyone interested in robotics.
Technological Capabilities
OpenCat supports various programming languages, including block-based coding, C/C++, and Python. Its platform allows for the creation of sophisticated gaits, locomotion, and inverse kinematics, translating simulated projects into real-world applications.
Applications and Integrations
Users have leveraged OpenCat for several advanced projects:
- Autonomous movement and object detection
- Robotics projects with Raspberry Pi
- NVIDIA Isaac simulations and reinforcement learning
- Visual and lidar-based SLAM with ROS
- Imitation learning with Tiny Machine Learning Models
- IoT automation with AWS to enhance worker safety
- 3D-printed accessories and DIY robotics projects
Hardware and Setup
OpenCat uses a customized Arduino-Uno board along with high-performance servos for fluid movements like walking, running, and backflipping. It supports various add-ons, including sensors and cameras, enhancing its perception and AI capabilities.
Setup Process
Setting up OpenCat involves configuring the NyBoard, a process documented in detail through Petoi’s resources. The setup process is simplified with easy-to-follow steps involving downloading the necessary files, configuring the board, calibrating sensors, and finalizing the build through a user-friendly app available on both Android and iOS.
Community and Support
OpenCat has seen success in crowdfunding and widespread adoption, thanks in part to a supportive global community. Extensive documentation, FAQs, and forums are available to assist users in their projects.
OpenCat is a perfect starting point for anyone interested in the exciting world of robotics, offering an accessible way to learn about and contribute to the future of robotic AI.
