Getting Started with Mindstorms NXT

5 stars based on 60 reviews

It could be hard to get the Sudoku Solver working. I have received emails from people who have built it but failed to make it work. So the software should be considered as a base for your own adjustments and tweakings which is very time consuming. Now I have warned you! Connect one of the 35 cm cable to the light sensor. The cable should run between the beams attached to the motor. Do this before step 55 of the building instructions. The most crucial part of the robot is the position of the light sensor.

It should be positioned approximately 1 mm above the surface. A plastic card should just fit under the sensor lego mindstorms education nxt software v2.1 download touching it. The files should be downloadable to the brick using the lego mindstorms software:.

You don't need the source code unless lego mindstorms education nxt software v2.1 download want to modify it or if you lego mindstorms education nxt software v2.1 download just curious. It could be viewed in notepad. Download - Sudoku Solver Note 1: Do this before step 55 of the building instructions Connect the wiring as follows: A plastic card should just fit under the sensor without touching it Attach a soft tip pen with rubber bands.

I used a Stabilo Pen 68 Downloading files to the brick Unzip sudokusolver. The files should be downloadable to the brick using the lego mindstorms software: Delete other program files and lego mindstorms education nxt software v2.1 download files etc to make room.

Update the NXT Firmware. I'm using NXT Firmware 1. Running Sudoku Solver Print the sudoku pdf. Note that it must have the original size.

Maybe you have to adjust the printer properties to avoid scaling or zooming. Tape one of the sudoku sheet to the surface. If you are using the empty grid and write the digits yourself, make sure the to write them with the same size as the digits of the printed sheets.

Adjust the height of the pen so that it touches the paper when the pen elevator is in it's lowest position. The pen should be set in upper position before starting the program.

Place the robot so that the wheels fits inside the squares. It's important that the robot is well centered sideways and aligned with the sudoku puzzle. The program starts with lowering the pen and drawing a short line. This is just a test to see if the pen is working and is correctly mounted. It's not that funny if the robot scans the whole sudoku puzzle which could take well over twenty minutes and then fails writing the digits because the pen doesn't reach down to the paper.

Source Code You don't need the source code unless you want to modify it or if you are just curious.
