Installing LEGO MINDSTORMS NXT Robot software Anyone ever try to install a LEGO Mind Storms NXT robot CD programming software on their 64-bit Win 7 OS? I keep getting memory errors but this is a new laptop with plenty of memory (Acer Aspire 5740 with 4 G RAM, 320 G HD, Core i3 processor).
Build your own LEGO® MINDSTORMS® or SPIKE™ Prime robot to solve the Rubik's Cube®.
Introduction
The MindCuber family is a group of robots, designed using LEGO MINDSTORMS and LEGO Education SPIKE Prime, that can solve the well known Rubik's Cube puzzle.
There is one variant of PrimeCuber that can be built from SPIKE Prime, two variants of MindCub3r that can be built from MINDSTORMS EV3 and two variants of MindCuber for MINDSTORMS NXT. Each variant uses a different selection of pieces. Please select which creation to build according to your SPIKE Prime, EV3 or NXT set.
LEGO Education SPIKE Prime
LEGO have produced at least one SPIKE Prime set:
- LEGO Education SPIKE Prime (item 45678)
Select PrimeCuber for your SPIKE Prime set:
LEGO MINDSTORMS EV3
LEGO have produced at least two different MINDSTORMS EV3 sets:
- LEGO MINDSTORMS EV3 (item 31313)
- LEGO MINDSTORMS Education EV3 Core Set (item 45544)
Omicron test universe software 2.4. MindCub3r for MINDSTORMS EV3 is available both for set 31313, home edition and for the Education sets 45544+45560
Select MindCub3r for your EV3 set:
LEGO MINDSTORMS NXT
LEGO have produced at least three different MINDSTORMS NXT sets:
- LEGO MINDSTORMS NXT 2.0 (item 8547)
- LEGO MINDSTORMS NXT (item 8527) - the original set in an 'Orange box'
- LEGO MINDSTORMS NXT Education Base Set (item 9797)
Each of these sets contains a progammable NXT 'Intelligent brick', three motors, a number of sensors and a collection of bricks, gears and other pieces. There is some variation between the sensors and pieces in each of these sets.
MindCuber uses a color sensor to detect the colors of the scrambled Rubik's Cube. A color sensor is included in the MINDSTORMS NXT 2.0 set. However, both the NXT 8527 (Orange box) set and the Education Base set include a simple light sensor that can measure brightness but not color. If you are planning to use either the '8527 or Education sets you will need to obtain an additional LEGO color sensor (item 9694). You may also need a few additional pieces if you are using the Education Base set

Free Mindstorms Nxt Building Instructions
Please read the General Tips before looking at a specific section to ensure that the most likely causes are eliminated first.
If after using this information you are still unable to resolve the issue, please leave a message on the MindCuber facebook page or on one of the MindCuber videos on YouTube describing the problem and what you have tried to resolve it.
Contents
1. General Tips
1.1 Build Instructions
Nobilis manual. This may seem obvious, but please check very carefully that MindCuber is built exactly as shown in the build instructions. There are several places where mistakes can easily be made that are difficult to spot. Some of them cause unexpected problems during operation.
Several common mistakes are described in later sections.
1.2 NXT Firmware Version
Check that the latest version of firmware, 1.31, is installed on the NXT.
If an earlier firmware version is installed, the MindCuber program may not run correctly because it requires functions that were not available in earlier versions or because of memory limitations.
The latest firmware is available from the Support section of the LEGO MINDSTORMS website. Download this firmware to the NXT using the standard LEGO MINDSTORMS software.
1.3 Executable Program Version
Check that the correct variant and latest version of the executable program, MindCuber.rxe v2.0, has been downloaded to the NXT. (Note: the v2.0 here refers to the software version, not the NXT version)
If the wrong variant is used, the motors, in particular the turntable motor, will move incorrectly because the gear ratio is different between the two variants. The Rubik's Cube will not turn or tilt as required
The latest version also has improved color discrimination for the most reliable scan.
The variant and version of the program are displayed on the NXT screen as soon as the program is run.
- The version is on the top line as 'MindCuber v2.0'.
- The variant is on the third line as 'NXT 2.0' or 'NXT (Orange box)' for the 8527 variant

1.4 Turntable Motor Alignment
When the MindCuber program is first run, the tilt arm and scan arm are moved automatically by the program to calibrate their positions. The turntable motor must be aligned manually.
Use the grey, left and right buttons on the NXT to carefully align the turntable motor when the program is running and waiting for a cube to be inserted. The motor should be aligned so that if the turntable is pushed gently by hand it will move sligtly and equally in each direction.
1.5 Batteries
Please try new or fully charged batteries in the NXT as several people have reported problems that disappeared when they replaced the batteries.
2. Scanning
MindCuber attempts to scan up to three times to try to determine the colors of the scrambled cube. If it fails, it will report either 'Cube error' or 'Scan error' at the end of the three attempts and flash the color sensor blue or red respectively.
2.1 Message 'Cube error'
This indicates that the colors appear to be correct and in the right combination for the pieces expected on the puzzle. However, it suggests that the cube has been taken apart and put back together in a way that is impossible to solve only by turning faces.
A cube will be impossible to solve normally if one corner piece or one edge piece has been twisted or if two pieces have been exchanged. Hp 620 wifi drivers. This can happen, for exampe if the cube is taken apart to adjust or lubricate it and put back together at random.
If this message is displayed, take the cube apart and put it back together completly solved. The scramble it by turning the faces of the cube as normal and try scanning again.

2.2 Message 'Scan error'
Scanning may be unreliable for a number of reasons including:
- The position of the color sensor is not as intended. Please check the build instructions very carefully as some subtle problems with parts connected in slightly the wrong place can have a significant effect on reliability.
- The battery voltage is low. Please check try new or fully charged batteries.
- The color sensor needs to be calibrated for the lighting conditions. This is described below.
- The lighting conditions are unsuitable. The color sensor produces its own light and bright lights can interfere with it so please try in low lighting conditions away from direct, bright lights.
- MindCuber is designed to work with the colors of a standard, Rubik's branded cube. It has been tested with a number of other cubes but expects one face with white stickers and the others to be yellow, red, orange, green and blue in any order. It has been tested successfully with several other cubes with varying levels of reliability. Note that if the cube has black stickers on one face instead of white, you can download and configure the program source code to expect this.
2.3 Calibrate the Color Sensor
Abhishekam serial today episode. The color sensor is affected by a number of things such as lighting conditions and the color of the stickers on the cube.
It can be calibrated for specific conditions by performing the following:
- Solve the white face of the Rubik's Cube
- Stop the program
- Start the program and then immediately press the orange button again and hold it until the screen says 'Calibrate white.'
- Insert the cube into the turntable with the white face upwards
- MindCuber will scan just the white face and then stop and display three numbers on the NXT display. It saves these numbers and uses them to calibrate the color sensor
- Remove the cube, scramble it and insert it again for a normal scan and solve
