Petoi Bittle robot dog - open source, quadruped

Petoi Bittle - Bionic Open-Source Robot Dog

Petoi Bittle is a small but agile and powerful bionic robot dog. It is an ideal tool for learning, teaching, and researching quadruped robots. With a custom Arduino board that coordinates all instinctive and complex movements, you can connect various sensors to enable additional "perception" through sensing. You could also add artificial intelligence capabilities by combining Bittle with a Raspberry Pi, ESP32, or another AI chip.

We have compiled more information about "Bittle" on the following website:

Bittle supports graphical (block-based) programming, Arduino, C, C++, and Python. Whether you are a beginner or an experienced engineer, you can bring Bittle to life in your own way. 

Features:

Unique Bionic System:
The unique bionic system can perform dynamic movements and offers excellent coordination. The bionic leg structure gives it greater freedom on unstructured terrain. This dynamic mobility has previously only been found in very high-priced robots from companies such as Boston Dynamics, Spot, or Sony Aibo.

Compatible with Multiple Programming Methods:
Bittle can be programmed at different levels in various programming environments, including the Arduino IDE for the C language and Codecraft for graphical (block-based) programming. Developers and STEM educators can also review and modify Bittle's C code, which is completely open source.

Custom Arduino Board:
Bittle is powered by NyBoard V1, a custom Arduino board with extensive peripherals (Atmega328P chip). It makes full use of the chip in a standard Arduino to coordinate complex movements. The board can drive at least 12 PWM servos, while an IMU (Inertial Measurement Unit) is used for balancing.

Extensive expandability:
A Raspberry Pi or other artificial intelligence chips can be installed to equip Bittle with more powerful artificial intelligence capabilities. The 4 Grove interfaces can be connected to external sensors such as ultrasonic and infrared sensors.

Easy to use:
Bittle is fully assembled and pre-programmed, making it ready to use immediately.

Comprehensive learning environment:
Bittle offers numerous course resources, 16 exclusive graphical programming courses, and expansion packs in English.
