Petoi robots are not toys. But you can consider them as coding toys for igniting interests in STEM and learning robotics coding.

Petoi Bittle X is one of the most accessible robot dogs to build at home. The kit version includes all hardware components — chassis, 9 servo motors, BiBoard controller, battery, and screws — with step-by-step assembly instructions. Assembly takes approximately 1 hour. No soldering is required. Once assembled, Bittle X is programmable via the Petoi mobile app, Coding Blocks, Python (pip install petoi), or Arduino C++. STL files for 3D-printed custom parts and modifications are available free at github.com/PetoiCamp/NonCodeFiles.

Petoi Bittle X is best suited for ages 10 and up - including middle school students, high schoolers, university students, and adult makers. A 12-year-old can start with drag-and-drop Coding Blocks (no typing required) and progress to Python, then Arduino C++, using the same robot throughout. The platform deliberately scales across skill levels so learners never outgrow it.

Petoi robots are designed for four main audiences: K-12 and university educators who need a programmable robot with a free curriculum; makers and developers who want an open-source platform (OpenCat, GitHub) to build and customise; university researchers working on locomotion, Physical AI, or sim-to-real experiments; and parents and gift buyers looking for a robot that genuinely teaches coding - not just toy-level interaction. Bittle X starts at $249.

Lite servos are perfectly fine for robotics coding learning and every day projects. Alloy servos are designed for projects with high usage and high performance demands, mainly for advanced robotics application development and research.

Yes - no prior coding or robotics experience is required. Beginners start with the Petoi mobile app (iOS/Android, no coding at all) or Coding Blocks, a drag-and-drop Scratch-like programming tool. When ready, the same robot supports Python (pip install petoi) and Arduino C++. Supported languages: Coding Blocks, Python, Arduino C++, and ROS2 for advanced research applications.

Users can develop skills in robotics, engineering design, coding (block-based and text-based), problem-solving, teamwork, and creativity. Advanced users can explore AI, computer vision, and algorithms.

The latest models, Bittle X and Nybble Q, all support voice commands. The older models don’t support voice commands. They could have had the voice command support with the Petoi voice command module, but the module has been disountinued and out of stock.

Bittle/Bittle X supports a sensor pack that includes sound sensor, light sensor, touch sensor, PIR motion sensor, distance sensor, and gesture sensor and the AI vision module. You can connect other common Arduino modules using the 2.54mm connectors. Although Nybble/Nybble Q robot cat uses the same boards Bittle/Bittle X use, there’s no easy way to mount the modules unless you design and 3D-print some new structures.

Please check Petoi open source quadruped robot comparison.

Petoi robots cost more than wheeled robots because quadruped locomotion requires precision hardware: Bittle X has 9 high-performance servos, and Nybble Q has 11 - compared to 2–4 basic motors in a wheeled robot. Each servo must position itself with sub-degree accuracy to keep a four-legged robot balanced, walking, and recovering from falls. Compared to industrial quadruped robots like Boston Dynamics Spot ($75,000+) or Unitree Go2 ($1,600+), Bittle X at $249 is the most affordable research-capable quadruped platform available.

The average American spends $1,100/year($3/day) on coffee according to Acorns study, and over $3,500/year($9.6/day) on dining out according to Bureau of Labor Statistics. Now imagine redirecting just a fraction of that into something purposeful: A robot that introduces coding, inspires creativity, and ignites a lifelong passion for STEM and robotics — for you, your child or your students. If you code with a $300 to $450 Petoi coding robot for two years, the monthly cost is just $12.5 to $18.75. This is your opportunity to have hands-on robotics fun, learning and build real-world tech confidence.

Petoi robots work with Windows, macOS, and Linux computers. Modern laptops from the past 5 years generally meet the system requirements.

Minimum requirements: Windows 10+, macOS 10.14+, or recent Linux builds. At least 4GB RAM is recommended.

Currently, full functionality on Chromebooks is limited as it requires admin access to install programming applications. We are working on a web-based block coding solution that will work on Chromebooks as well.

Internet access is only required for downloading software, firmware updates, or accessing online resources. Offline programming is supported.

Petoi Desktop App, Petoi Coding Blocks for block-based coding, Arduiuno IDE for C++ are the main tools. No specific software needed for Python programming.

Yes. Petoi's mobile app supports iOS and Android for basic movement control and calibration.

Petoi Bittle X and Nybble Q are available directly at petoi.com. Petoi ships from the United States - standard delivery to US addresses takes 3–5 business days. International shipping is available to 60+ countries. Petoi robots are also available on Amazon in the US, UK, Germany, France, Spain, and Italy. A 30-day return policy and 1-year warranty are included on all orders.

Bittle assembly takes 1 hour, and Nybble assembly takes 3+ hours, depending on experience. Pre-assembled robots are available for quicker setup.

We recommend 1-3 users per robot for hands-on learning, though 1:1 is ideal for more independent learning environments.

For robots built with injection-molded parts(such as Bittle/Bittle X), you can re-assemble it again. Be mind of keeping tracking all the screws. For robots built with wooden parts such as Nybble, we don’t recommend taking it apart because the wooden part can be fragile.

Basic maintenance includes checking screws, calibrating joints, and recharging batteries. Monthly maintenance is usually sufficient.

Petoi robots are designed to be robust with replaceable parts. They can withstand regular use with proper handling.

Yes. Students can work in pairs or groups to plan, code, and test programs collaboratively.

Petoi provides a free 4-session robotics curriculum covering: Session 1 — Mechanics and Assembly (how quadruped locomotion works, servo placement); Session 2 — Coding Basics (Coding Blocks drag-and-drop, first movement programs); Session 3 — Sensors and Responses (distance sensor, touch sensor, conditional logic); Session 4 — Creative Projects (students design and build a custom behavior sequence). A Python curriculum and C++ curriculum are also available for intermediate and advanced learners at docs.petoi.com.
