They’re doing it with an FPGA, with homebrew robot arms to twist and turn a rainbow cube into the correct position.įirst, the mechanical portion of the build. Here’s a really fast way to do it.Ĭontinue reading “Rubik’s Solver Uses FAC Machine Building System” → Posted in Robots Hacks, Toy Hacks Tagged cube solver, FAC system, rubik's cube solver, rubiks cubeįor their final project for ECE 5760 at Cornell,, , and are solving Rubik’s Cubes. It is possible to build a solver with just two swiveling grippers.
After a brief pause to compute the solution the grippers go to work. These work in conjunction with the color sensor gantry to scan every side of the cube. First you place the randomized cube on the insertion platform which retracts after the cube is in the grasp of the grippers. You’ll want to watch the demo video below. handled the software which runs on a Rapsberry Pi Compute module. If you’ve used FAC before we want to hear what you think of it in the comments.
Those include an insertion platform for getting the cube in and out, a gantry for three color sensors, and two axes (three grippers in all) for doing the actual solving. must be a master with the system the layout of the machine appears simple and uncrowded despite the multiple degrees of freedom built into it. This is the first time we remember hearing about the FAC system, which is a standard set of parts which can be used to make any number of mechanical systems. We love a good Rubik’s Cube solver and the mechanical engineering on this one is both elegant and functional.
