Summary by the author

his 3D-printed Raspberry Pi-powered Rubik’s Cube solving robot has everything any serious robot does — arms, servos, gears, vision, artificial intelligence, and a task to complete. If you want to introduce robotics to your kids or your students, this is the perfect machine for it.

This one-eyed four-armed giant stands 35cm (14″) tall. 70 hours of print time and an entire spool of filament are needed to print it, not to mention over $200 worth of hardware, but once fully operational, it will surely wow your friends and neighbors. Scramble your Rubik’s cube, place it in the robot’s grippers, press a button, and then sit back and watch this amazingly smart and stunningly beautiful machine put it back together. Watch the video!

This robot is fully 3D-printable. Other that 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.

1 AC/DC adaptater 6V 3A (3000 mA) power

This robot uses the SMAKN power supply adapter (shown here), with the round plug replaced by two female connectors to be plugged into the Pololu servo controller. The replacing was done by a competent technician proficient in soldering. Use a wall plug at your own risk. See the Connecting Electronics section below for more information.
