PiCrawler is a Raspberry Pi–based quadruped robot with an aluminum alloy structure. It features a camera module for color recognition and face detection, 12 metal-gear servos for walking and dynamic movements, an ultrasonic sensor for obstacle detection, and a Robot HAT with a built-in speaker for expressive sound effects.

This documentation includes the parts list, assembly guide, Robot HAT introduction, and PiCrawler programming tutorials.

Programming is divided into three chapters:

• Play with Python: More experienced users can program PiCrawler directly using Python.

• Play with Ezblock: Use Ezblock Studio for graphical programming.

• See · Hear · Respond— AI-Powered with Multi-LLMs: Add speech and AI interaction with multiple LLM backends.
