Tilted Twister: Lego Mindstorms Rubik's Cube Solver Special thanks to for releasing free building instructions, operating instructions, and source code to the public! This is a Lego Mindstorms robot called Tilted Twister. It uses 3 Motors, a touch sensor, and a Hitechnic color sensor (available at http to tilt, rotate, and twist a cube to solve it. It also uses an Ultrasonic sensor to know when you place a Rubik's cube in its grasp, or if the cube falls off the turntable by accident. What is really impressive about this robot, is how it can solve a Rubik's cube using only the elements of the retail kit of Lego Mindstorms (unless you are using a color sensor like me), and it can solve a cube without the use of a webcam, or a connection to a computer! The robot first uses a motor attached to a color sensor to scan all the colors of a cube, as well as using the turn-table motor and the grabber-arm motor to assist in this. Then, it resolves the center, edge, and corner colors of the cube, and generates 3 solutions using an optimized "corners first" method. It picks the solution with the least face turns (moves), and begins solving the cube. I have modified the robot a tiny bit by moving the color sensor up one level so that it can read the colors better. You could also use a light sensor for this robot, but then you would need to replace some colors on the cube or else the light sensor may not be able to see a difference in color between all 6 colors on the cube, therefore messing up the scanning and ...

Sudoku solver program - Backtrack algorithm in C# Download link: people.inf.elte.hu This is a sudoku solver with backtrack algorithm which was written in C#. It has three heuristics. 1. From index: choose where to start from and then go from left to right and row after row. 2. Random: choose the next position comletely random. 3. Best position: calculate the position which has the least posibilities and write there.

ARM Powered LEGO/Nokia 4x4x4 Rubik's Cube Solver Possibly the first ever 4x4x4 LEGO Rubik's Cube solver? This Rubik's Cube solver was designed and programmed using a Nokia N95 mobile phone, a LEGO Mindstorms NXT and lots of LEGO technic pieces!

ARM Powered Nokia and LEGO Rubik's Cube Solver This Rubik's Cube solver was designed and programmed using a Nokia N95 mobile phone, a LEGO Mindstorms NXT and lots of yellow LEGO technic pieces! This is a Java application running on the Nokia N95. This communicates with the NXT using a simple control program via Bluetooth. The embedded camera in the N95 is used to capture an image of each face of the cube. The application then processes these images to determine the colour of each piece of the cube. Then the solution is worked out in a couple of seconds resulting in a sequence of approximately 30 moves. The N95 then transmits these moves one at a time to the NXT to solve the puzzle. This normally takes 3-4 minutes in real-time.

LEGO NXT Rubik's Cube solver (FINAL version) This is our completed Rubik's cube solving robot. Here we see the entire process. First it scans the surface of the cube (so it knows the initial state) and then it solves it entirely by itself. I would like to emphasize that the robot solves the cube without help from a pc.

Sudoku Solver Batch Program Script available from: This program literally solves Sudoku puzzles. You simply enter in the puzzle that you want solved and the program will work it out. The program solves the puzzle using the methods that you or I use, using logic only. It does NOT "hard crack" ie take thousands of guesses. It solves the puzzle step by step, you can see every number entered and its location. It can solve virtually every easy and moderate puzzle, and the vast majority of hard puzzles. Puzzles rated more difficult than hard are often not solvable using solely the methods that this program uses. The program is in one single batch file, written entirely in batch. There are no other files needed or created. Thanks to CrazyMonkey124 for the idea of a Sudoku solving program.

The Autonomous Maze Solver (AMS) This is an autonomous ("self-solving") maze we built for ECE 5770 at Utah State University. We used an 8051, servos, webcam, OpenCV computer vision library, PID controller, a Linux system, and a whole lot of Python a C (around 5000 lines of code) to make it all work. This video was edited with the free, open source program OpenShot.
