NXT 2.0 Rubik's Cube solver

The repository contains three projects:

This is the main project of the Rubik's Cube solver contains the PC application

This project contains the application that runs on the NXT, intended to receive commands from the PC application

This project contains the unit tests

• Java SE Development Kit 7 - 32 bit
• LEGO® MINDSTORMS® NXT 2.0
• leJOS NXJ
• Eclipse IDE for Java Developers - 32 bit
• leJOS NXJ Plug-in for Eclipse

First, build the NXT project and upload it to the brick using leJOS NXJ Plug-in in Eclipse. Only then build the PC project and run it. Upon running it will automaticlly connect to the NXT.

• Solve cube
  Use this option after completing necessary calibration steps for solving the cube
• Tests
  
  This menu contains all of the robot's tests recommended to run to validate all robot's operations:
  • Brute force - performs random robot's operations
  • Read color - read current color and print result to logger
  • Flip cube - perfors cube flipping operations
• Calibration
  
  This menu contains all of the robot's calibration routines:
  • Color sensor - calibrate white color reading, place white color below the sensor and press Enter
  • Color motor - calibrate the color sensor motor. Follow the instructions of the program to calibrate the color sensor to it's three optional positions. Use the < and > buttons to rotate the motor
  • Cube tray - calibrate the cube's tray motor. Use the < and > buttons to rotate the tray to be aligned
  • Proximity - read the current proximity sensor data
  • Color light - read the current background light. Use it to make sure the lighting condition of the room are suitable for the color sensor:
    • Light okay
      
    • Light too strong
      
• Pattern
  
  This menu contains additional patterns for cube solving:
  • Plus minus
  • 4 cross
  • Cube cube
  • Cube cube cube

Please complete the required steps before solving the cube:

1. Run and complete the calibration methods: Color sensor, Color motor and Cube tray
2. Make sure light conditions are okay with Color light calibration option
3. Run the Brute force test to make sure everything is okay
