Say hi to Sourino, a robotic mouse for kitties (and kiddos)

Sourino — which comes from the French word for mouse, “souris,” plus Arduino — is a small robot by 11-year-old maker Electrocat, meant to entertain kitties and kids alike.

The device features a 3D-printed body roughly shaped like a mouse, controlled by a Nano along with three HC-SR04 ultrasonic sensors poking out for autonomous navigation. An IR sensor is implemented for remote operation, and two small gearmotors with a driver board enable it to move around on the floor.

As seen in the video below, Sourino is able to travel a path made out of books and interact with (more like drive crazy!) the house cat. Full build instructions are found here, including a parts list, Arduino code, and CAD files.
