S.I.T.O

systematical individual thought operator

this is my lego 'MINDSTORM' robot i got for christmas yesterday
it has an ultra sonic sound sensor that can measure how far away it is from an object by emitting a high pitch sound and measures how long it takes for the echo to come back [the sound in not loud enough for our primitive ears to hear]
it also has colour vision so u can tell it to go to the darkest shade of green in a range of 100 inches for example and a touch sensor and sound sensor

this is my first invention but not my last
