Petoi Smart Robot Dog & Cat Comparison
Petoi intelligent robot pets come in two flavors currently: robot cat Nybble and robot dog Bittle.
History
Nybble was born and "raised"(aka crowdfunded) by a few thousands of early backers from Indiegogo in 2018. Bittle was born and "raised" on Kickstarter and Indiegogo in 2020 and has continued to evolve with the rollout of Bittle STEM kit and Bittle X with voice control.
Software
They run on OpenCat, Petoi's open source quadruped robot framework. They are highly programmable quadruped robots, and support varies modules and sensors that are compatible with Arduino. So you can really gift them some intelligence. They are also compatible with Petoi mobile app and desktop app for convenient calibration, controlling, and programming with new robotics skills.
Look & Feel
Nybble has more of a retro look with wooden frames and pieces. Bittle is made out of durable and high-impact injection-molding material, and is more sturdy. As the 2nd generation of Petoi's robot, Bittle has more impressive dynamic agility and can perform self-right, frontflip and backflip.
Bittle and Nybble are affordable, agile and very cute in the eye of the beholder. Their frames are designed to have very few screws involved. The cat has more human-like head and knee joints and is loved by many kids. However, the interlocking wooden frame may pose a challenging puzzle for beginners. The assembling of Bittle is more like a clip-on experience and can be done in one hour. We also keep simplifying the software configuration so that users can make the robot work faster, as an encouragement for deeper exploration with this highly extensible framework.
Applications
Bitlte and Nybble are both great for learning coding and quadruped robotics in STEM education as well as developing real-world four-legged robot applications and performing related research. They also make great unique gifts to kids learning about robotics and coding and to geeks/engineers/programmers who are into building their own robots and programming smart robots.
