Gently mix up the colored sides of the cube, set it down for just a moment, and it will spring to life, sorting itself out again. You can find all kinds of robots at Bay Area Maker Faire, but far and away the most interesting bot this year is the Self-Solving Rubik’s Cube built by. If only all the world’s problems were as simple as a jumbled up toy from the 1970s.Ĭontinue reading “Rubik’s Cube Solver Does It In 4.56 Seconds” → Posted in Robots Hacks, Toy Hacks Tagged cube solver, robotic rubik's cube solver, rubik's cube solver, rubiks cube It’s funny to think that way back in 2011, both robots and humans were so much slower at solving cubes. Even with six actuators, that’s not fast enough to beat the human world record of 3.47 seconds, but it’s still pretty darn good. Once the cube’s state is loaded into the program, though, the mechanical job of solving the cube can be achieved in under five seconds. Instead, the cube’s status must be input to a web app on an attached computer. The design doesn’t feature a machine vision system to capture the state of the cube.
Purists will note, however, that the steppers are fitted with adapters that slot directly into modified center squares on the cube. It runs six stepper motors via TMC2208 drivers, enabling it to directly actuate each face of the cube. The robot relies on a Teensy 4.1 microcontroller to run the show, paired with its Ethernet kit for connectivity. was a long way off that speed, but his robot is an absolute demon that solves at a rapid pace. Speed cubers can solve a 3×3 cube in under ten seconds these days, after all. However, to compete at the top level, you’ll have to train hard. Solving Rubik’s Cubes is a learnable skill.
