Finnish maker and engineering student Miska Karvonen has invented what may be the world’s best cat toy (besides humans). It’s the Cat Laser Entertainer Robot, which uses the familiar red laser dot to entertain your cat when your attention has flagged and the cat is still intent on hunting. This one, made from 3D printed parts using a couple of servos, an Arduino board with a simple shield, a 9v batter, and a few other components, moves the red dot around in random, jerky motions like a human would. You can make your own robotic cat toy by following Karvonen’s instructions on his Instructables and MakerBot Thingiverse pages.
