This time I re-built a LEGO NXT in the form of a Segway (or an inverted pendulum) and tried to balance it using a light sensor. It is clear that with a gyroscope it will be much easier and precise; but this sensor is not included in the regular LEGO NXT, you have to buy it separetely.
I found the building instructions here. I think there are much more stable designs in the web that are more stable than this one: but this one seems so funny and remembers me of the security men at my college (which are useless and have the brain the size of a penny. Actually I always have the urge to make them fall when I see them).
See??
My next blog will talk about programming the control law using the LEGO NXT ROBOTICS toolkit from Labview.
