As I am getting older, and a Gobot would drive away too quickly, I decided = to reprogram a Knob-block to act as a limiter. No matter how much input it = gets, it's output will never exceed the knob-setting. The Distance block's input is used to sense the closeness of your hand. It = drives the Rotate block, which holds a BarGraph block as the tail. The Knob= block than provides limited signal to the three (for stability) Drive bloc= ks, the Speaker (it squawks) and the Flashlight (it winks at you).
