Design and Inspiration

RoboBunny is based on PicoCat version 2, which was originally based on OpenCat. I uses the pimoroni Servo 2040 all-in-one 18 servo microcontroller, powered by the Raspberry Pi RP2040.


RoboBunny features a new head & ear profile, modified rear legs as well as a pom-pom floofy tail.
