Introduction to FASTBot operations – Light based.
Light Following.
Light following involves following or tracking a source of light. Light following is a common robotic behaviour in robotics. The sensors used for light following are usually analog sensors, which can measure light intensity. The FASTBot has two light sensors specifically for this application.
The Light sensors are placed at the left and right sides of the robot. The action of the robot depends on the value of the left and right sensor readings. Generally, the robot turns towards the side having a higher intensity of light.
Light Following Algorithm.
Both light sensors are checked continuously. If the left light sensor reads a higher value than right light sensor, then the robot is turned slightly to the left. But, if the right light sensor reads a higher value, then the robot is turned slightly to the right. Thus the robot follows the light source.
Light Avoidance.
Light avoidance involves avoiding and moving away from sources of light. Light following is a common robotic behaviour in robotics. The sensors used for light following are analog sensors, which can measure light intensity. The FASTBot has two light sensors specifically for light based applications.
The Light sensors are placed at the left and right sides of the robot. The action of the robot depends on the value of the left and right sensor readings. Generally, the robot turns towards the side having a lesser intensity of light.
Light Avoiding
Both light sensors are checked continuously. If the left light sensor reads a higher value than right light sensor, then the robot is turned slightly to the right. But, if the right light sensor reads a higher value, then the robot is turned slightly to the left. Thus the robot avoids the light source.
