I'm currently developing a Lego Robot, the mindstorm series to be specific. I want to replace the lego NXT brick with an arduino, maybe an intel galileo in the future. How do I establish connections from the arduino with the lego sensors? Also, I would like some input on any cool features that I can add to this robot. This robot is to be seen as a human companion. Thanks in advance.
An example of a sensor i would like to use is here : http://www.hitechnic.com/cgi-bin/commerce.cgi?preadd=action&key=NIS1070
How do I interface this with an arduino?
