This workshop is a specialization course in line following and precision robotics.

Line following is an upcoming activity in the Indian Robotics Scenario. Almost every other college technical festival offers a problem statement based on line following robots. But, its application is not just limited to robotics competitions. Line following is an important ability in industrial robots too.. we will see a day when autonomous automobiles run at your command..

This workshop covers advanced line following techniques. Grid Solving/ Line maze Solving are all derivatives of the line following robot. These derivatives will also be covered.

Stepper motors are an important part of robotics. Precise Open Loop systems can be achieved best by stepper motors. This workshop will give you a detailed exposure to stepper motors. We will focus specially on the use of stepper motors for the purpose on line following/ Grid Solving.


The concepts that will be covered in the 2 day span are:-

Introduction to Line Follower Based Robots

  • Autonomous Robots
  • Need for line follower based robots
  • Basic Funda
  • Industrial applications

Introduction to the AVR Microcontroller

  • About AVR
  • Features of AVR
  • Programming AVR

I/O ports

  • Configuring and using the I/O pins of the AVR Microcontroller
