Building A Robot: The Proximity Sensor

An Overview Of The Building A Robot: The Proximity Sensor
           Getting feedback through sensors is important when building a robot because without any type of feedback the robot does not know about the world that surrounds it. By adding a proximity sensor our robot can now 'see' things infront of it. In this article we made the robot react to something that moved too close to the robot, alternatively the robot could also react if it moved too close to something else.

What To Do Now
           Just as with Part 1: The Chassis and Part 2: Motor Control you're going to have to wait until Part 4: Multiple Sensors is released before you can move forward, but I'll give you a quick preview of a great next step: adding more sensors for feedback! Imagine if you have two, three or four proximity sensors on this robot, you could detect objects in all different directions, wouldn't that be awesome? Another thing that this robot sorely needs is to be able to drive straight. One of the tires is a little off and it makes the robot veer a little bit to one side, when supposedly driving straight.

           This article meant to achieve a few goals that we set out in the purpose and all of them were achieved. The most important goal was to create a robot that could sense the outside world by adding a proximity sensor to it, and making it smarter. When my hand closed in on the robot, it warned me and ultimately ran away from me when I got within distance of grabbing it. The squealing noise the robot makes through the speaker is a fun pleasantry and I hope it makes this robot have a bit more of a human touch or feeling when it operates. With that, I'll declare this Part 3, a success. Let's move on to Part 4!
