This was built to start using the Microsoft Robotics studio. The Lego is a stock NXT with a "Crystal Reaper" track set. Some sensors are not part of the NXT kit and were made from CDS cells for light and two micro switches for the front bumpers. This robot is capable of running in full autonomous mode, auto over bluetooth with MSRS, and as well in RC mode over bluetooth working with a X-Box USB controller.
