This is an unofficial design proposal for Rongzhong Li’s very impressive OpenCat project.
I hope to be able to update this project when the original design files are made openly available.

OpenCat is a robotic cat capable of surprisingly lifelike behaviour. Standard MG92B servos controlled by a custom driver board and a Raspberry Pi enable it to walk. It is able to navigate using ultrasonic distance sensors in the eyes.

All the parts can be printed on widely available FDM 3D printers.
