Chapter 8. Tutorial: Introduction to Sensors

Sensor information can be used by your robot to navigate and interact with its environment. Sensors report on the world around them; measuring light, distance, sound, movement, direction, temperature, pressure, or location. This chapter describes how common sensors used with two wheeled and four wheeled platforms work.

The first half of this chapter covers the primary sensors used in the chapters that follow: IR reflective sensors and SONAR distance sensors. These are used to determine if an object is near the robot. Reflective sensors detect nearby objects and are used for line following and edge detection (determining if the robot is near the edge of the surface it is moving on, such as the edge of ...
