FAQ
How much does the Petoi Bittle X cost?
The Petoi Bittle X is priced at approximately $299–399 and is available directly at petoi.com and through Amazon. It is the upgraded version of the original Bittle, featuring an aluminium alloy frame replacing the original's laser-cut wood structure.
What is the Petoi Bittle X used for?
Bittle X is an open-source quadruped robot dog designed for STEM education, robotics research, and maker experimentation — specifically for learning legged locomotion, gait programming, and embedded systems development. It supports Python, Arduino, and ROS development environments, and its OpenCat open-source firmware has an active global developer community.
What is the difference between Petoi Bittle X and the original Bittle?
The Bittle X upgrades the original Bittle's laser-cut wood structure to an aluminium alloy frame — significantly improving durability for outdoor use and drop resistance. The core electronics, OpenCat firmware, and servo configuration are shared between both versions. Bittle X is recommended for users wanting a more durable platform for long-term research or active outdoor experiments.
Who is the Petoi Bittle X designed for?
Bittle X targets three audiences: university students and researchers studying legged robotics at an affordable entry price; STEM educators teaching robotics with a physical, programmable platform; and hobbyist developers who want to build custom behaviours using the OpenCat community's libraries and extensions. At under $400 it is the most affordable metal-frame quadruped robot available.
How does the Petoi Bittle X compare to the Unitree Go1 Air?
Bittle X ($299–399, ~480g) and Go1 Air ($1,599–2,199, 12 kg) are both quadruped robots with open SDKs, but at entirely different scales and capability levels. Bittle X is a palm-sized desktop research and education platform; Go1 Air is a full-scale robot dog capable of outdoor terrain traversal and stair climbing. Bittle X is the entry point for quadruped exploration; Go1 Air is for serious robotics research requiring real-world locomotion performance.
