Black Line Following Robot without Microcontroller

Hi all,

Welcome to Jay Robotics Club, Research team. We feel immense pleasure in introducing ourselves, in this very article we shall see about how to build a simple line following robots using very simple IC’s. Before you could start, I will list out the components required.

Components Required

  • Breadboard
  • Breadboard wires
  • 9 volt battery
  • Battery snaps
  • IC 7805
  • 10uf capacitor
  • Led
  • 1k resistor
  • 10k resistor
  • 220 ohms resistor
  • IR sensor module – 2
  • Motor driver IC like (l293d, l298d, uln2003)
  • Robot chassis
  • 12volt DC motor
  • Wheels -2

How it works

  • At first, this article will not go much deeper into technical specification of its electronic components, but it can guide you (or) it can act as a catalyst as we always do in our jay robotics club
  • Fix motors, wheels on robot chassis at appropriate places
  • Place breadboard on top of the chassis
  • Google for “5 volt circuit using 7805” as many people have given their circuits, it would be appropriate to use them
  • Place sensors in front of chassis facing the floor adjacent to each other
  • You can use any of the motor driver IC (l298d, l293d, uln2003) and many more but every time our preference is L293d
  • And the circuit goes like.
