EXPERIMENT 2: Navigating with Feeler Sensors Autonomously
The purpose of this experiment is to introduce you to sensors. Program switches (feelers) and also infrared sensors as input sensors to allow your robot to navigate autonomously. Imagine creating your first smart robot already! We start with something as simple as a bumper switch that when the robot hits a wall for example it triggers the robot to go backwards and move in another directions. We will also be introduced to using infrared sensors to detect objects ahead of time before running into them or to follow an object. You will learn about voltage sinking and sourcing voltages, using a mechanical switch to trigger a function and some neat Arduino tricks.
