Frequently Asked Questions

🧠 General Questions

Are Petoi robots toys?

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

What age group or grade level is Petoi best suited for?

Petoi robots are best suited for 10+ years old elementary students, middle school to university-level students, adults and even seniors, depending on how deeply you want to explore robotics and programming. With beginner-friendly tools and advanced capabilities, they scale well across age groups.

Who are Petoi robots designed for?

Petoi robots are designed for anyone with an interest in STEM, robotics, AI, computer science, engineering, mechanic, mechatronics, and physical computing.
  • Grandparents/parents encouraging their grandkids/kids to start with STEM, robotics, and AI
  • K12/college/training school students
  • Students and professors interested in AI & robotics
  • Developers, engineers, robotics, and maker enthusiasts interested in creating their own robotics projects and applications.
  • STEM, robotics, and AI educators.  Please check the educator purchase guide and FAQ for more information.

Should I choose lite servos or alloy servos?

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.

Can Petoi robots be used without prior robotics or coding experience?  What programming languages do they support?

Absolutely. Beginners can start with the mobile app or graphical programming tools like Petoi Coding Blocks and Petoi Skill Composer, while more advanced students can use C++ with Arduino IDE and Python.

What types of learning outcomes can users/students achieve using Petoi robots?

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.

What connection methods do Petoi robots support?

  • Wired serial connection
  • BlueTooth
  • WiFi

Do Petoi robots support voice commands?

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.

Where are your open-source codes?

Please check

What are the supporting modules/add-ons for your robots?

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.

Where can I find documentation and tutorials?

What are the differences between your robots?

Why are Petoi programmable robots more expensive than other forms of robots?

Our robots are more expensive than other forms of robots(such as wheeled robots) because Bittle/Bittle X has 9 high-performance servos and Nybble/Nybble Q has 11 high-performance servos. In compaison, a 4-wheeled robot has two or four basic servos that don't support or need precise positioning. The development of complex kinematics and control of a lifelike quadruped is also much more complex.

How does the cost of a Petoi robot compare to everyday expenses like coffee or dining out?

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.

Frequently Asked Questions

💻 Technical & Device Requirements

What type of laptops or computers are required to use Petoi robots?

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

Is there a minimum operating system or hardware spec?

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

Are Chromebooks supported?

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.

Is internet access required to operate or program the robot?

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

What software or apps are needed to get started?

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.

Are Petoi robots compatible with mobile devices or tablets?

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

What connection methods do Petoi robots support?

  • Wired serial connection
  • BlueTooth
  • WiFi

Frequently Asked Questions

🪠 Setup & Maintenance

How much time does it take to assemble and set up the robot?

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

Can multiple users share one robot?

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

After I assemble a robot, can I take it apart and re-assemble it again?

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.

Do the robots require maintenance? If so, how often?

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

How durable are the robots?

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

Can multiple students program the same robot?

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

Frequently Asked Questions

🌐 Integration & Expansion

Can Petoi robots integrate with platforms like Arduino, Raspberry Pi or other single board computers?

  • Yes. Petoi robots are Arduino and Raspberry Pi compatible.  
  • They support communication with an optional microcontroller/computer(such as Raspberry Pi, Nvidia Jetson Nano, micro:bit) through wired or wireless connections. The control structure of both the wired and wireless connections is based on serial UART.
  • Both Nybble/Nybble Q and Bittle/Bittle X support connecting to a Raspberry Pi directly (Bittle/Bittle X will prefer smaller Pi models like Pi 3A+ and Pi Zero).  You can check the robot comparison page for Raspberry P compatibility.  You may need to 3D print extra support structures for your project. Here's the 3D-printed Pi-support for Bittle.
  • All of our robots run on NyBoard/BiBoard which can power the Pi and communicate with the Pi through the serial port in the 2x5 socket. A basic communication Python module and sample codes are included in OpenCat/SerilaMaster.
  • For other Pi models and MicroBit, they can be wired to the robot but have some geometric constraints.
  • Jetson Nano is too big for robots, so only the wireless connection is recommended.

Are there APIs or SDKs for advanced programming?

Yes. Developers can access Petoi’s open-source libraries and API documentation for deeper control via https://github.com/PetoiCamp/OpenCat/.

Is there support for AI, machine learning, or vision modules?

Advanced modules such as the AI vision module can be added, additional processing power can be acquired with Raspberry Pi for running AI models and more advanced modules.

Can I 3D print custom parts or modify the hardware and software?

Yes. Petoi provides STL files for selective parts and encourages hardware customization and creative modifications.  You can also modify the open source firmware OpenCat to suit your needs.
