These unsolved Rubik’s Cubes do have a tendency to gather dust on our shelves or vanish into drawers. Somehow, they remind us of how easy it is to screw things up and then stubbornly ignore the problems we’ve created. With that semi-philosophical remake, let us introduce a machine that will get your guilty conscience out of the way. Also, it‘s a perfect excuse for firing up your 3D printer.

This 3D-printed Rubik’s Cube solving robot is Raspberry Pi-powered. It has everything any serious robot does — arms, servos, gears, vision, artificial intelligence and a task to complete.

You put the scrambled Rubik’s Cube in its mechanical grippers, sit back and watch robot will start and turn and twist until the puzzle is solved. Take a look here:

Prepare for 70 Hours of 3D Printing for the Rubik’s Cube Solving Machine

This robot is fully 3D-printable. Other than the servos, servo horns, camera, electronics and a few dozen bolts and nuts, it has no traditionally manufactured parts. Absolutely no soldering or breadboarding is required.

The one-eyed four-armed giant will stand 35cm (14″) tall. It will take 70 hours of print time and an entire 1-kilogram-spool of filament. Not to mention over $200 worth of hardware (mainly the Raspberry Pi and its camera). But once fully operational, it will surely wow your friends and neighbors.

If you want to introduce robotics to your kids or your students, this is a great machine to do it.

The robot was designed by O.T. Vinta, who already brought the 3D printing community a lot of sophisticated designs. You can find the designs on Thingiverse.
