When it comes to data logging and viewing readings from the virtual robots sensors there are three levels of reporting:
1.) Visualizers: Are a graphical representation of what the virtual robots sensors are seeing. To enable visualizers, click on the 'Render' menu and check 'visualizers'.
2.) You can use the LEGO Mindstorms 'Port view' option on the virtual brick.
3.)For a more detailed account of what the sensors are seeing, click on the 'Real-time' data button on the Toolkit's toolbar.
