Canonical robot record
Overview
Petoi Nybble is an open-source robot cat sold as a build-it-yourself kit aimed at makers, robotics hobbyists, and STEM education. Buyers assemble the quadruped themselves and then bring it to life through code, making it both a hardware project and a programming platform.
Once built, Nybble can perform a range of lifelike, cat-inspired motions such as walking, sitting, stretching, and balancing, and it can be extended with new tricks and behaviours. It is controlled by a customised Arduino-compatible board and supports several programming approaches, from drag-and-drop blocks to C++ and Python.
Nybble runs on OpenCat, Petoi's open-source quadruped robotic-pet framework, which grew out of founder Rongzhong Li's robotic-pet project. The open-source nature lets users inspect, modify, and share the software that drives the robot.
RoboZaps maintains this record as part of its canonical robotics database. Specs are source-verified where linked; the record compares public facts across manufacturers rather than representing a single robot maker.
