# 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.

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++](https://www.petoi.com/pages/free-cplusplus-quadruped-robotics-curriculum) and [Petoi Coding Blocks](https://www.petoi.com/pages/free-quadruped-robotics-curriculum-scratch-coding)(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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://guide.petoi.com/product/quaddle-under-construction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
