LABORATORY EXPERIMENTS FOR DEMONSTRATION
The following experiments can either be demonstrated physically by the teacher using a Kit/ using audio- visual material.
Alternatively, these may be taken up as group projects under the guidance of the teacher.
Programmable Mobile Robots:
*Line follower, Obstacle avoidance and Edge Detection Mobile Robots.
Note: The purpose of these laboratory experiments is to familiarize students with robotics systems and are not a part of the
evaluation.
*A line follower robot will be able to follow a drawn line on the floor and move accordingly. An obstacle avoidance robot will
be able to detect any solid object that comes along its path and change its direction to avoid it. An edge detection mobile robot
will move on the table be able to detect the edges and prevent itself from falling off the table.
All these are excellent examples of sensors in action. These robots can help in understanding how the sensors interface with
the microcontrollers to automate a specific tasks.
A plethora of examples of these systems are found in manufacturing plants, autonomous driving vehicles, space programs,
automatic vacuum cleaners etc.
The fundamental design of these robots are strategically placed sensors which enable them to work in a more specialised
manner. Both the Line Following and Edge Detection Robots employ a couple of IR sensors but their placement makes them
perform different tasks.
In case of Line Follower, the IR sensors are placed close to each other to help in following a predefined path whereas, the edge
detector has widely placed IR sensors to maximise coverage area thus preventing itself from falling off from a surface. The
Obstacle Avoider Robot employs an Ultrasonic Sensor which automatically detects if any object comes in front of it at a pre-
defined distance and changes its course accordingly.
