Scribble Pad

[runix]

Hello,

I am working on a small project in which the NXT will pay the role of a Scribble Pad. I will build the robot similar to this: http://www.nxtprograms.com/scribble/index.html

Can anyone give me an idea of how to read the values from the the two motors and transform them into Cartesian coordinates (x, y) on the LCD display.
Should I use the getAngle API or something similar?

Thank you.

The value of Motor.B and Motor.C.getTachoCount() increases/decreses by 1 for every degree the motor axis moves.

The rest should be simple math.

Thank you Skoehler. I think that this should do it.
