This project is about a line follower robot that I made for my collage fest. Actually these kinds of robots will be the beginning of enthusiasts like us. Line follower robots are very well used in industries where the robots have to follow a fixed path embedded in the floor. These bots are being widely used in packaging industries.
Things Used:
- Arduino UNO
- Brushed motors -2
- Proximity sensors-3
- L298 motor driver-1
- 9 volts battery
- Gripped Wheels-2
- Connecting wires
- Acrylic sheet (“for designing body”)
- Castor wheel
- Some Screws
How this works?
These bots work with infrared sensors commonly known as proximity sensors. IR LED emits invisible electromagnetic waves (Infra-Red waves) and photo-diode captures back the waves. We are using the system to detect the line (black line white surface). Arduino uno: Arduino UNO is an open-source micro-controller board based on the ATmega328P micro-controller. The board is equipped with sets of digital and analog input/output (I/O).The board has 14 Digital pins, 6 Analog pins, and programmable with the Arduino-IDE via USB cable. It can be powered by an external 9V battery, though it accepts voltages between 7 and 20 volts. Motor driver: In this project i used L298N H-Bridge driver module. But in simulation I used L293D IC. But I recommend you to use L298N module. Since the driver IC we used is a dual full bridge driver IC we can control two motors simultaneously using individual inputs. Input signal voltage should be 5v motor supply voltage is up to 45v, peak output current is 2A. |
