Quaddle (Under construction)

Getting Started

Quaddle is an open-source robotics kit for makers, hackers & STEAM educators. Learn robotics, coding, AI, and 3D printing on one desk robot — then personalize its looks, tricks, and AI persona to make it yours.

All three product models support controller operation.

The small but mighty Quaddle has these fantastic features:

• World's first 4-servo omnidirectional robot dog. Fast running, gliding, sideways motion, and crisp in-place spins—all with just four servos. Less complexity. More possibilities.
• Learn & replay your tricks. Physically guide Quaddle through any movement — no code or app needed. Just tap to record and replay via its feedback servos.
• Support Petoi Coding Blocks(block-based Scratch-like), C++, and Python.
• Free C++ and Petoi Coding Blocks(block-based Scratch-like) curricula.
• Equipped with a Motion core board (AI core board on Buddy/Scout), a high-performance ESP32S3 development board supporting additional modules for robotics/AI conversation/IoT applications.
