How to use the QR Code Generator robot skillThe QR Code Generator will create a QR Code with the text you enter. By default, the QR Code text is "Synthiam," and the QR Code Graphic is the same. Using your phone's QR Code Scanner App to scan the graphic will say "Synthiam." This control works in conjunction with the Camera Control.
The Camera Control can be set to recognize QR Codes. When you view the Camera Config, look under the Scripts tab and notice the QR Code Scripts. You can specify a different script to execute for each QR Code that is recognized. There is also the ability to create a script that will execute every QR Code found but not recognized within the list. You may use this script to detect a web URL and open the web browser, as in the QR Code Example (Found under Examples Menu Bar Option).
You will find a selection for Variables in the Camera Config's Script Tab under the Camera Control. The detected QR Code text will be stored in the specified variable.
More text within a QR Code increases the resolution required for detection. This means if your QR Code contains the letter "A," it will be much easier to detect than if it had the word "Apple." This is something to consider when creating custom QR Codes for your Synthiam Application. If you want the robot to detect the QR Code easily, choose short QR Codes. We usually recommend using a single letter or number.
*Help: There are example projects for this control. Please look under "Examples" within ARC

I realize that it is setting up a variable for each QR code but is it possible to encode a x,y,z location in in the variable. Say you have a wall full of products and you want to find a certain item, you could move the camera close to the xyz location then the Qr tracking could kick in to retrieve the item. Rather than making multiple variables for each x y z location of an item possibly just make a long number and then decode the number. Example x=12 y=18 z=45 so item "oil can"=33 could be turned into a number also. 33121845 and a script could decode the number. I've asked for spreadsheets but for some reason -probably really slows it down- it was never made but now you can see why I'm asking. How could you do that in Blockly?
