What it solves

OpenCat provides an affordable, open-source platform for quadruped mini robots, making agile robot kits accessible to researchers, educators, and makers rather than limiting them to high-budget laboratories.

How it works

It serves as a codebase and hardware platform for mini quadruped robots (like Nybble and Bittle), supporting gait research, reinforcement learning (RL), and sim2real workflows. The project focuses on bringing down the cost of complex robotic systems through mass production and open collaboration.

Who it’s for

• Skilled makers interested in building and hacking robotic kits.
• K-12 robotics classrooms and university research labs using the platform for physical AI education and applications.
• Researchers focusing on gait design and reinforcement learning.

Highlights

• Physical AI Platform: Designed for real-world applications and education rather than screen-based coding.
• Citations: Cited in over 20 academic papers.
• Widespread Adoption: Over 30,000 robots shipped across 60+ countries.
• Open Source: A collaborative project aimed at making quadruped robotics affordable and hackable.
