What modules could be used to convert green laser lines to red so the images can work with the laser line module?
You could use the SwapColor module (its an example of how to create new plugins in RoboRealm) which can be used to swap the green and red channels.
But since green lasers are becoming more popular we have instead updated the laser modules to also detect green. You should be able to run the attached robofile after downloading the latest copy.
My robot's green laser line is now recognized by the module. Thank you for the nice upgrade!
