Build a self-balancing Lego robot in 30 minutes

Laurens Valk shares how to make a Lego Segway using a standard NXT set plus a HiTechnic gyro sensor. One of the most notable features of the robot is that it packs NXT-G, the unadmired “default” programming language driving the NXT microcontroller brick. Up until now, all Lego Segways used one of the high-octane alternatives to NXT-G, including one of the first self-balancing Lego bots created, the LegWay. So for Valk to figure out how to do it using NXT-G is pretty cool.
