Simple control logic

Turning a reading into an action

Here is where it all comes together. A robot constantly turns sensor readings into actions using simple logic, usually if and else. Imagine an obstacle-avoiding car with a distance sensor. The rule: if something is closer than 20 cm, stop; otherwise, go.

Run it. That tiny function is real robot logic. Change the 20 to make the car more or less cautious, and run it again.
