Bar code reader is written in the NXT-G environment to give to everyone the possibility to use it in its project.
Following these simple steps you can realize your own barcode driven robot!
- Equip your explorer robot with the light sensor pointed to the floor to a distance of 1,0 -1,5 cm from it (see close up in gallery).
- Download the BarCodeReader block and save it under your my blocks directory (usually C:\Documents and Settings\
\Documents\LEGO Creations\MINDSTORMS Projects\Profiles\Default\Blocks\My Blocks) - Download the Excel file containing the bar code and print them or make your own barcodes following these simple rules.
- Make your project using the BarCodeReader block with input in NumOfBar plug of number of black strips of your code -1. If you use the BarCode.xls file downloaded from this site, the right value is 5. Read the page Technical Informations for furter informations.
- Optionally, you can download the GetStarted sample project (remember to copy the BarCodeReader block in the right position -see step 2)
In this case remember that the right sheet to use is the one labeled 23-30. - A black bar is recognized if the ligth sensor read a value < 45. A Value >=45 is interpreted as a white bar. Before launch the program place the light sensor of the robot in a black and in a white area. If the black value or the white area are near to the trigger value of 45 take the right action:
- move the light sensor a litlle up or down;
- make a more darker print of the barcode;
-change the trigger value by editing the barcode.rbt block. (Advanced user only).

The Flusher:
The flusher is mounted under the toilet bowl cover for the extra weight. Flushing requires no gearing, the NXT motor is strong enough to flush every time.
The NXT and Manual Flush:
The program for this robot is a little complicated in the NXT graphical language. It would be much simpler to understand in a traditional language like Java.
The Ultrasonic Sensor:
The ultrasonic sensor waits till it detects someone in range, then waits till that person is out of range. A polite thank you, and then flush!
