Building A Robot: The Proximity Sensor

Data & Observations
           Once you have the firmware loaded onto the PIC and all the hardware assembled, you've finished building a robot with a sensor. Remember the sensor is telling the robot about the outside world, and the firmware we built makes our robot pretty shy. We need to interact with it in order to see the robot come to life. Take a look at the video below to see what we've just finished building.

           As you can see the system works pretty well and the robot seems...dare I say a little cute? When my hand approaches the robot, it warns me with some LEDs turning on and if my hand gets within grasp of the robot it screams through the speaker, moves backward and drives away. All exactly as planned!
