Overview

The robot cat that launched Petoi and the OpenCat framework via an Indiegogo campaign in 2018. A laser-cut wooden frame on hobby servos, it is the ancestor of the more popular Bittle. Its final stock has sold out; Petoi now sells the redesigned Nybble Q, and Bittle X is the better buy for most.
