Hammer Head The Line-Follower Robot

Published on


🌟 About the Project

Introducing HammerHead, a simple line follower robot powered by the ATmega328 microcontroller and TCRT5000 IR sensors. This Robot is equipped with N20 motors, an L293D motor driver, and some features that make line-following an enjoyable journey.


🎯 Features

  • × Advanced Line Following: With the aid of TCRT5000 IR sensors, Hammer Head excels in tracking lines efficiently, offering a delightful experience.
  • × ATmega328 Brain: The brain behind this marvel, the ATmega328, orchestrates its every movement, ensuring flawless navigation.
  • × Buzzer and Neopixel: It has an integrated buzzer, producing a short sound when the robot detects a line. The neopixel displays red and green lights to indicate its operational status.
  • × User-Friendly Operation: A simple push button initiates or halts the robot’s movement, making it user-friendly.


🚀 Get Started

Step 1: Gathering Components

Collect the essential components including the ATmega328 microcontroller, TCRT5000 IR sensors, N20 motors, L293D motor driver, chassis, wheels, and battery.

Step 2: Schematic Design

Create a detailed schematic that illustrates the connection between components, ensuring accuracy and functionality.

Step 3: PCB Assembly

Prepare and assemble the PCB by connecting the components, ensuring proper layout and connections.

Step 4: Power Management

As the motor driver requires 5V, integrate the MT3608 voltage booster or XL6009 for power regulation and stability.

Step 5: Coding the ATmega328

Utilize the provided code to program the ATmega328. This code enables the robot to perform basic movements and utilize sensors for line following.

Step 6: Testing and Refinement

Test the robot on various line patterns. Refine the code and robot configuration to improve its performance.


⚠ Future Changes: Adding High RPM Motors

Prepare for future enhancements by considering the inclusion of high RPM motors for increased speed and responsiveness.
